viewpoint COMEDY CENTRAL office !

Let’s be honest, Corporal Jones himself couldn’t have made a more botched job of calming the nation’s collective anxiety in the face of what seems to be one self-inflicted adversity after another. The hapless Dad’s Army character, and his famous “Don’t Panic! Don’t Panic!” catchphrase, may have been well intentioned, but inevitably always had the exact opposite effect on his spooked comrades who, it must be said, seem to bear an uncanny resemblance to certain members of this Government. In fact, if you haven’t tried it yet, a match-up of traits is a mildly amusing way to pass a couple of hours stuck in an angry forecourt queue attempting to fill up or idly parked on the M25 thanks to the irresponsible actions of a motley crew of ill-informed tarmac huggers.

It seems you can shuffle the ranks as much as you like, but ultimately you end up with yet another ill-disciplined rabble of foot soldiers whose principle objective is to don a flak jacket and resolutely deflect as much blame for a particular crisis on their predecessors’ obvious lack of foresight. Whatever happened to the old well-worn adage of prevention is always better than cure? Brexit has now been almost five years in the making, and Covid-19 around since March 2020, so it’s fair to ask why certain persons who are afforded – at great expense – positions of huge responsibility, with massive internal resources and real industry expertise at their disposal, are consistently left in a state of flux.

It doesn’t take an Eddie Stobart to work out that somewhere down the line the UK would face a chronic shortage of HGV drivers, which would in turn lead to desperately low levels of the key components essential for a fully functioning society. That’s day one for anyone taking up office in the Ministry of Transport, surely, and who knew that CO2 was vital in the wellbeing of our livestock industry? Well, maybe, just maybe, that’s something that might be of interest to the Minister responsible for food and agriculture. What none of them ever seem to comprehend is that we live in very different times to when a local problem could be kept as just that. Thanks to social media, and twenty-four hour news channels, with vast voids to fill, every situation of once mild concern “After so many false dawns, we have is now up for intense scrutiny and – apparently stopped believing what we through hearsay and fevered speculation – very quickly are told by those in high office, whatever transforms into a national crisis. their political colour or agenda.”

And don’t get us started on the underwhelming performance of the Home Secretary in “dealing” with the ridiculous posturing of the Insulate Britain bandwagoners who clearly don’t do irony. In the main, these are the same rag tag and bobtail virtue signallers who bought the capital to a standstill last summer with their Extinction Rebellion antics and were treated with kid gloves and comical dad dancing by HM Police Force. It’s not as if they aspire to come up with anything really creative or inventive to further (what handled more sensitively could garner strong public support) their cause and keep the police on their toes. Many have already appeared numerous times before a magistrate to have their sticky hands slapped, the authorities know where they live and operate from, yet they are given carte blanche to travel unchallenged each day and cause mayhem to businesses and essential services playing a vital role in getting the country back on its feet after so much adversity. Anyone else would be forcibly man-handled away before you could say Superglue but, for reasons that dare not speak their name in these woke times, they are consistently indulged by the powers that be. Damned if they do, damned if they don’t, so let’s hope it just goes away would appear to be the modern mantra but, as it’s been said many times before, hope is not a strategy for anyone, let alone an elected Government.

Despite the get tough rhetoric, and cast iron assurances, sadly, no one is holding their breath that we aren’t heading for another winter of 1970s-type discontent although this time…..without the comedy classics and great music to provide some much needed relief. In fact, anyone old enough to have been around in the those darkly depressing days will recall, with impending doom, the prospect of the endless weeks of power cuts and candles, empty fuel pumps, rubbish piling up in the streets, and three day weeks for businesses that were literally on their knees begging for financial help. Back then – quite rightly – we were referred to as “the sick man of Europe”. Now, as we lurch from one black comedy moment to another, we are increasingly being seen as the “funny man of Europe”. And, unfortunately, the joke, as with our unsuspecting and oblivious Corporal Jones, is actually on all of us right now.

GRANT AND GROAN

THE BIG BREW

Builders urged to join in charity ‘Big Brew’ to tackle mental health crisis

Government handling of Green Homes Grant Voucher Scheme blasted by National Audit Office (NAO) A report on the ill-fated Green Homes Grant Voucher Scheme, has found that a rushed delivery and implementation significantly reduced the benefits that might have been achieved. It also urges the Department for Business, Energy and Industrial Strategy (BEIS), along with HM Treasury, to heed lessons from the failure of the scheme. The initiative offered homeowners and residential landlords vouchers worth up to £5,000, or £10,000 for those on low incomes, to pay for fitting measures to cut carbon in homes, such as insulation, or new doors and windows, as well as the installation of low carbon heating.

While there was a high level of interest, installers complained about its complexity, delays issuing and paying vouchers, and the requirement and cost associated with participating traders having to meet both the registration requirements and also certification for associated quality standards.

CLEARING THE AIR

HSE’s inspectors will be targeting construction firms to check their health standards The campaign will focus on respiratory risks and occupational lung disease, looking at the measures in place to protect workers’ lungs from construction dust including silica, asbestos and wood dust. The initiative will be supported by HSE’s WorkRight campaign, which encourages builders to download free guidance and advice. More than 3,500 builders die each year from cancers related to their work, with thousands more cases of ill-health and working days lost.

WINNING STRATEGY

Extinction Rebellion should support the National Retrofit Strategy (NRS) An Extinction Rebellion (XR) splinter group called ‘Insulate Britain’ have been blocking motorways to bring attention to their strategy to insulate British homes. Rico Wojtulewicz, head of housing and planning policy for the National Federation of Builders (NFB), said: “XR are going about this the wrong way. There is already a document which industry supports called the National Retrofit Strategy (NRS) but rather than supporting and amplifying the policy, XR have taken it, ignored the vital elements which make it work and overlaid it with some of their concepts so they can claim a strategy of their own.”

In response to the announced pause of planning reforms in England, there’s concern that this will further delay moves to support SME developers to build, according to the Federation of Master Builders (FMB). “Almost half of small house builders say that the planning system is one of the biggest constraints on their ability to build more homes,” comments Brian Berry, Chief Executive of the FMB. “Forty years ago, small builders delivered 40 per cent of new homes; but today it’s just 12 per cent. We won’t fix our broken housing market if we don’t make it easier for SMEs to build the highquality homes they are known for, in their local communities.”

Builders urged to switch to electricity for powering site machinery

CAUGHT IN A NET

Concerns raised over suitability of UK domestic heating systems in journey to net zero The Heating and Hotwater Industry Council (HHIC) is urging government to consider the suitability of current UK domestic heating systems to facilitate the transition to Net Zero. Retrofitting homes with lowcarbon technologies, like heat pumps and hydrogen boilers, will be key to meeting the UK’s Net Zero targets. However, many of the different heating systems that circulate heat and hot water in properties are not currently appropriate for these emerging technologies. To outline where improvements need to be made the HHIC has launched a whitepaper entitled Heating up to Net Zero.

MERCHANT SALES WHAT LIES

Construction firms are being urged to ditch diesel and use electricity to power site machinery, enabling them to cut carbon emissions by 97 per cent, by the National Federation of Builders (NFB).

The trade body has partnered with energy consultants, Utility Team to help builders secure a green temporary building supply offering electricity from renewable sources for up to three years.

NFB chief executive Richard Beresford said: "Due to its intensive processes and reliance on diesel generation, the construction industry has always been a heavy energy user. In turn, there has been a significant amount of carbon emissions released into the atmosphere."

He added that most construction firms should be phasing out all their diesel generators and switching to having a green temporary building supply.

Incentives to do so will increase once tax rebates of 46.81 pence per litre on red diesel, which has a marker dye, finish in April 2022. Currently, the levy on red diesel is 11.41 pence per litre but in April it will be the same levy as white diesel of 57.95 pence per litre.

Historically, contractors have shied away from using temporary building supplies because of the infrastructure cost and the time taken to negotiate supply with distribution network officers.

The Builders Merchant Building Index (BMBI) reveals continued growth

A 14.5 per cent higher year-onyear increase was helped by buoyant timber & joinery products sales (+42.4 per cent) – the highest ever monthly figure since the BMBI report began. Elsewhere, the kitchens & bathrooms sector (+13.9 per cent) chalked up its highest sales for 12 months. Compared to July 2019, a more normal pre-pandemic year, total merchant sales were 13.1 per cent up.

Grant Engineering achieves biofuel breakthrough

Over the past few years the Grant Engineering R&D Team have been working on more sustainable and carbon saving fuels for its condensing boilers. Field trials have successfully demonstrated that using a 100 per cent biofuel Stephen Grant, Founder of Grant known as Hydrotreated Vegetable Engineering Oil (HVO) can result in reduction in carbon emissions of up to 88 per cent. It will allow rural properties to transition to a renewable alternative at an affordable cost and with minimum disruption, especially in older buildings where retrofitting a heat pump can be complicated.

COMING UP SHORT

High demand is fueling longer lead times, finds industry leaders

According to the latest statement from John Newcomb, CEO of the Builders Merchants Federation and Peter Caplehorn, CEO of the Construction Products Association, there has been a slight levelling off in construction demand, mostly in the domestic repair, maintenance and improvement sector, but it still remains high. Product supply has improved slightly with lead times stabilising in some areas. That said, certain items – timber battens, chipboard, steel lintels and PVC products – remain in short supply. The main concerns are around bricks and blocks, concrete roof tiles, and bagged cement.

A MATERIAL QUESTION Dear Professional Builder Just wanted to say I really appreciated reading the editorial on materials shortages. Thank you for raising the concerns we are all feeling currently. I’ve been in construction since leaving college, in all domestic sectors for the last 20 years – as a developer, sole trader and sub-contractor. I’m currently based in Penzance Cornwall, where I’ve been for 15 years.

I’ve never known things to be this uncertain. Basic materials are running out and I’m concerned that the SMEs – particularly sole traders – are going to get a massive shock if they haven’t made stock and supply contingencies for the autumn.

I expect the large developers and main contractors are buying stock on allocation or to hold in their yards so they can keep going.

That’s fine if you have a decent credit limit, and get good terms, but if you’re a small outfit and cash flow is tight, then we small firms could all get creamed by this situation as the big boys get first call it seems. Maybe Mr Sunak would consider a VAT break on materials......?

HEALTH OF A NATION Dear Professional Builder I’ve been reading your coverage of the issue of mental health in the building industry with interest, and the space that you’re giving this issue is commendable. I won’t give my name – or any other details – but I’ve seen first-hand the devastating effects this issue can have on individuals and their families. The taboo that surrounds the problem needs to be tackled head on.

Name withheld on request There are now a number of organisations doing good work in this area and Professional Builder has a section of our website dedicated to the issue. Use the link below to find out some of the latest developments in mental health in construction.

SPECIAL REPORT MASTER BUILDER OF THE YEAR

t was once the property of Henry V’s standard bearer at the Battle of Agincourt, and now this Grade II listed medieval hall in the Cotswolds has been transformed into a luxury modern home. In recognition of their expertise in the renovation work, Stonewood Builders were recently crowned the overall winner at this year’s Federation of Master Builders’ national Master Builder Awards.

now leads a firm which has been trading for more than 50 years, and is very proud of the traditions that they uphold.

“We specialise in luxury and bespoke residential projects, and around 60 per cent of what we do is refurbishment and conservation. Renovating period properties and listed buildings is something we’re particularly proficient at, and it was those skills that were in evidence in the south Gloucestershire project. There’s a beauty evident in what we do and a level of skills to match.”

The heartland for Stonewood Builders is amongst the Cotswolds, where natural stone and traditional buildings abound. At

the same time, the contractor has equally embraced the contemporary when called upon, and has produced a number of ontrend open-plan zinc and glass constructions for its clients.

Prestigious history it may well have, but when the client took over what would ultimately become a Master Builder of the Year winning job it was cold, draughty and damp. “There are always surprises when you embark on the renovation of a period building and we found quite a few roof timbers and beams that weren’t holding very much up,” Jamie reveals, “but that’s always to be expected when

014_PB_NOV21_Layout 1 07/10/2021 10:44 Page 15

you’re delving into something of this age, with parts of the structure dating back as far as the 12th century. One of the biggest surprises, however, was in uncovering a reformation-era priest hole, which provided an escape route for practising Catholics during the time of their persecution, which is not something we had encountered before.”

In common with many old buildings, at various points in its long life, the medieval hall had suffered from unsympathetic attempts at repair. The current owners were, however, determined to renew its original period features wherever possible – whilst upgrading it to modern standards – and in Stonewood Builders they had the perfect partner to realise that vision. “The building work has transformed the space into a warm and welcoming family home and that’s a testament to the team we had on site,” continues Jamie.

Traditional skills

Stonewood Builders’ craftspeople are well-versed in the intricacies of traditional construction techniques, and that knowledge was brought to bear on this survivor from the middle-ages. Horsehair lime plaster was utilised on oak or chestnut laths, for example, as well as decorating with lime wash, whilst the firm set up a mobile workshop on site in order to undertake the repairs to the oak staircase and panelling in the great hall.

Indeed, on past jobs the company has

making sure that the lime mortar used is in harmony with the type of stone. For us detail is paramount, and we’ve devoted considerable time and resources to ensuring we’ve got a group of craftspeople on the books who can deliver the results that our projects demand.”

“Much of the success of any building project is based on collaboration and communication,” enthuses Jamie. “It’s something that was much in evidence on this build, with the homeowner, architect, interior designer, and builder all coming together to produce the best possible outcome. That’s really what we’re about – working with people to produce very highquality work. We’re always very open and honest about what can be achieved, and we strive to make the renovation experience an enjoyable one for the client.” even been known to undertake the manufacture of their own hot lime mortar mix on site and have regularly scoured the purveyors of reclaimed materials in order to find the perfect match.

“For the sake of structural integrity we had to replace some of the oak beams, but one of our carpenters devoted a lot of time to ageing and distressing them in order to complement the original woodwork and in the end you couldn’t actually tell the difference between old and new. Similarly, yoghurt was used to facilitate a suitable patina on any new stonework, and we’ll take great care in

Prestigious accolade

The Master Builder Awards recognise building excellence, quality craftsmanship, and exceptional customer service, and are run by the largest trade association in the UK construction sector, which is this year celebrating its 80th anniversary.

Stonewood Builders acknowledge the value of such recognition and have been regional winners of FMB accolades previously. “The prestige that Master Builder of the Year status confers on us as a contractor will undoubtedly result in more exposure for the work that we do – and its quality,” adds Jamie. “We don’t advertise, and our work is generated on the basis of reputation, so anything that can enhance that will be welcome.”

“We do appreciate what a valuable role the FMB performs in promoting best practise and we’re very proud to be members,” he concludes. “The promotion of the highest levels of professionalism in the industry, and the level of respect that it offers to the best builders, is something we’ve always aspired to – it’s a great organisation.”

SPECIAL REPORT INSULATION

© smuki/Adobe Stock

ALL ABOUT EAVES

In the third instalment of our feature on future building materials and solutions, Professional Builder’s Lee Jones listens to sustainable building expert Dr Matthew Brooke-Peat about the direction of travel for developments in insulation. f we are to have any hope of achieving our carbon reduction targets then one of the key battle grounds will be in our existing housing stock, particularly in upgrading their thermal performance. Whilst recent initiatives like the Green Homes Grant may have floundered the market for suitable insulation methods is set to expand exponentially, and new approaches will be required.

In a bid to find viable solutions for builders, the government is striving to address the issue, not least with new and more stringent regulations, but also by bringing the academic and the manufacturing world together. Through his work with Leeds Beckett University’s Leeds Sustainability Institute (LSI) Dr Matthew Brooke-Peat is involved in one of

I

I

those collaborations, and it is an initiative that is already promising rewards.

“We have a heritage in the LSI of researching the building performance of dwellings and have been successful in influencing changes to Building Regulations,” explains the academic institute’s Architectural Technology Course Director. “Whilst we’ve highlighted problems to industry it would be fair to say we’ve been less adept at finding solutions. There is no doubt that one of the areas that needs to be tackled in either residential retrofit or housebuilding is thermal bridging. It will be a common theme for the future, and one that we ourselves identified back in 2014.”

That insight was the inspiration for the development of the Retrofit Eaves

18 NOVEMBER 2021 PROFESSIONAL BUILDER

Thermal imaging will reveal the extent of the problem in many pitched roof buildings

Insulator (REI), a concept that Matthew has invented and patented with his colleague Professor Christopher Gorse, and that could represent the first in a series of innovations. With funding from a Government Knowledge Transfer Partnership (KTP) via Innovate UK – and as part of a two-year initiative with ambitions to develop similar products – his solution will now be taken towards the manufacturing stage with the help of ARC Building Solutions, a specialist in cavity fire barriers and cavity closers. Thanks to support from academic experts at LSI and

018_PB_NOV21_Layout 1 07/10/2021 10:45 Page 19

New Series NO.3 the Leeds Business School, the insulation supplier is setting up its own product development division with ambitions to bring these ideas to fruition.

Matthew outlines how the REI works: “Whilst the junction between wall and roof has regularly been identified as a problem, both in new build and refurb work, the market hasn’t come up with an answer for retrofit, not least because fitting it into the eaves, filling the void appropriately, and maintaining any ventilation that might be required is difficult to deliver. The patent for the Retrofit Eaves Insulator (REI) involves a hinged semi rigid backing material, which includes the option of a ventilator tray. Beneath that sits a mineral wool insulation quilt, which provides not only the necessary thermal performance but also fire resistance. That hinging means it can be folded for transport and then recover once installed to fill the void being insulated. Multiple units could be easily transferred into a loft space by an installer, who will then simply push it into the roof space, with the material then expanding to fill the void. Insulation that’s laid at ceiling level could then be subsequently installed up to the back of the REI.”

Thermal bridging

Through modelling and prototypes, his team are confident that the concept works, and is part of a wider theme in finding other solutions around thermal bridging. Indeed, the idea of mechanically compressing insulation, and then releasing it to fill a confined space with restricted access, could have applications around doors and windows, for example, and form a part of more comprehensive external or internal insulation upgrade to a property.

As the recent hike in energy bills has demonstrated the imperative for new insulation products is not just in reducing Restricted or difficult to access spaces can undermine the continuity of insulation in a property

The Retrofit Eaves Insulator (REI) is designed to insulate the difficult junction between wall and roof

carbon emissions but also in dragging significant numbers of people out of a damaging fuel poverty trap. When it comes to thermal bridging, where high rates of heat loss can often be experienced, the conundrum is how to do that in spaces which are often inherently difficult to access.

“The challenge is to maintain continuity of insulation in a dwelling and the concept of recoverable insulation is certainly something that has more scope for development,” continues the lead academic on the project, “particularly since it has clear advantages in relation to thermal bridging.”

Indeed, one of the distinct advantages of the idea of recoverable insulation is that it’s a distinctly low-tech solution. All of the materials that are required to make it are already freely available and, whilst mineral wool has been used as the example here, other forms of insulation could just as easily be utilised.

“To be honest, it’s such a simple concept that, whilst I’ve been on this journey, I’ve often wondered why nobody has thought of it previously,” enthuses Matthew. “If you point a thermal imaging camera at many pitched roof buildings insulated at flat ceiling level, the problem is immediately visible, which makes its potential vast. In retrofit installations, where you’re navigating around an existing structure and fabric, thermal bridging is a real challenge, and it can be a difficult issue to overcome.”

Similarly, Matthew and his team at the LSI have previously been involved in research on the performance of thin internal wall insulation (TIWI), looking at what the optimum range and amount of material should be. “Whether it’s an internal, external or cavity wall solution, too much insulation has the potential to cause problems to the existing building fabric,” he concludes. “That’s why, particularly when it comes to retrofit, any insulation installation will need to take into account what’s already there. Given the range of building types in existence that is itself a significant task for the industry.”

SPECIAL REPORT SUSTAINABILITY

A SUSTAINABLE

PATH W ith 97 per cent of the materials that make up the Marshalls product range sourced from these shores the manufacturer is able to conveniently side-step many of the problems the industry is currently experiencing with imported commodities.

That’s not the only benefit, of course, because that ‘Made in Britain’ moniker – and the reduction in energy miles it entails – is a considerable advantage in an era when sustainability is at the very top of the agenda, and that’s just one area where the company is keeping a very careful track of its carbon footprint.

As the external landscaping specialist’s Group Sustainability Director, it is the job of Chris Harrop OBE to challenge the business across a whole raft of environmental parameters, and his enthusiasm and

Combating climate change is the great challenge of our age and the way we build is crucial to our success. Professional Builder’s Lee Jones talks to Chris Harrop OBE about what Marshalls is doing to address the issue.

engagement with the task speaks volumes for how seriously the company takes its responsibilities. “We’ve been looking at issues of sustainability for more than 20 years now and have been reporting on our CO2 emissions since 2004,” explains Chris.

“It was clear then that the issue of climate change, and the future role of building materials and our built environment, would be the industry’s guiding principle and that’s certainly the case. That would then develop in 2008 into a partnership with the Carbon Trust to provide a carbon footprint for each of the products in the Marshalls’ range, and today customers have access to cradle to grave calculations of this kind for over 5,000 products.”

Recycled

As a result, it can be demonstrated that the carbon footprint of the company’s concrete products has effectively halved over that timescale, and

some of the biggest wins have been in the mix. Marshalls has pioneered the use of recycled material, for example, including pulverized fuel ash from the energy sector, a by-product of steel-making in ground granulated blast-furnace slag (GGBS), as well as limestone powder. Each of these can be utilised to reduce the embodied cement content – a CO2 intensive commodity – with no detriment to the functionality, performance, longevity or aesthetic of the finished product.

Moreover, with the adoption of 100 per cent renewable energy in its production processes, the reduction of waste through automation – and one of Europe’s most efficient concrete block plants soon to come online – even products that do not include these substitutes have a significantly reduced carbon footprint.

In addition, Marshalls recently launched a new Bricks & Masonry division. A key component of that part of the business is its concrete facing bricks, which can claim just under 50 per cent less embodied carbon content than a

SPECIAL REPORT SUSTAINABILITY

traditional clay alternative. Concrete bricks have a very low water and cement content, are made from recyclable material, and there’s no need for firing in a kiln, as there is with clay.

“If more housebuilders were to specify concrete bricks in their projects the carbon savings would actually be huge,” continues Chris. “One interesting fact about concrete is that, thanks to a process of continuous carbonation, it actually sequesters CO2 over the lifetime of the product. If you take the example of paving, for instance, 19 per cent of the CO2 in its manufacture is then reabsorbed. That’s why it’s very important to make any calculations on carbon footprint on a whole life basis. In that context, the durability of a material, as well as recyclability, is significant. Put simply, the longer it lasts, and whether it can be reused, the less CO2 it will ultimately consume. That’s why, in order to ensure that a material can last 50 years and more, our approach to sustainability will equally focus on the likes of compressive strength, UV stability and water absorbency.”

Whilst every manufacturer should, of course, be following the Marshalls example, and doing everything it can to reduce the environmental impact of its current portfolio, it also has to be recognised that we are just an estimated

11 years away from the point at which human activity raises global average temperatures by 1 ½ degrees. Whilst that might sound like a modest increase, it’s more than enough to precipitate disruptive weather patterns. Essentially, regardless of what we do here and now some of the changes are effectively locked in. With flooding and periods of drought more common, water management and sustainable urban drainage schemes will take on much greater importance. Similarly, episodes of extreme heat will bring the urban heat island effect into sharp focus, and the part that building materials can play in ameliorating the threat.

“We’ve been doing massive amounts of research on permeable paving, and that’s reflected in the Marshalls’ solutions now available. With a 100-year storms now likely to occur more frequently, linear drainage channels will need to increase in capacity, rain gardens will become more common as well as a greater overall appreciation of the interface between hard and soft landscaping areas. In a world where water is set to become an increasingly scarce resource, schemes that can capture and utilise it will also emerge as compulsory features.”

Marshalls Driveline Priora is a sustainable urban drainage system that comes in a range of colours, sizes and textures. It’s designed so that water will percolate through the joints, which means that no additional drainage is required – or planning permission. Similarly, urban heat issues are being addressed with a greater appreciation of thermal mass, whilst products are now being designed with their ability to reflect solar heat very much in mind.

“Essentially it comes down to creating better futures for everybody,” concludes Chris. “Whether it’s socially, economically or environmentally, the materials we choose to build with can have a huge impact on our well-being.”

TOWERING AMBITION C

There’s a tower for every job – and a PASMA training course to match

ompleting a PASMA Towers for Users course means you’re trained to work safely with mobile access towers – with a PASMA card to prove it – and can take on more responsibility on site. But did you know there’s also a range of upskilling opportunities now open to you?

Beyond Towers for Users

Towers for Users is a popular entry-level course which teaches operatives about mobile access towers – that’s a straight up and down, single bay structure. There is, however, a range of other towers available for use on more challenging sites, to overcome obstacles or to create larger platforms. Anyone who has completed Towers for Users is eligible to undertake further training on five of these additional tower configurations, which all fall under product standard BS 1139-6: 씰 Towers on Stairways 씰 Cantilever Towers 씰 Linked Towers 씰 Towers with Bridges 씰 Large Deck Towers Each type of tower has its own dedicated PASMA training course, so you can learn the specialist skills and knowledge needed to assemble, dismantle, move and inspect them. The courses also focus on components, potential dangers and required precautions.

The training courses

■ Towers on Stairways for Users Stepped towers are designed to be used on a stairway – a spot where access is often tricky. In fact, they can also be used in other places where each end of base of the tower

will be at different heights. Delegates are introduced to techniques for working on stepped surfaces and with components such as portal frames and props.

■ Cantilever Towers for Users Cantilever towers are useful for overcoming obstacles, like window apertures, riser shafts or porches, as they have a platform protruding out from the tower. This course introduces techniques such as using ballast to stabilise a tower and enabling components such as cantilever frames and frame links. Plus, delegates learn about the different safe working load capabilities of cantilever towers.

■ Linked Towers for Users Linked towers provide extra platform space and are often used to span the facade of buildings. This course introduces techniques for linking towers and enabling components such as walkthrough and step-through end frames.

■ Towers with Bridges for Users A tower with a bridge – that’s two or more towers connected by a bridge – provides a long, uninterrupted platform with a clear space at ground level. This means it can span an obstruction or leave an access route for vehicles or

pedestrians. This course introduces new techniques for connecting towers and spanning obstacles, as well as enabling components such as bridge beams.

■ Large Deck Towers for Users A large deck tower is an arrangement of towers and platforms that have been joined together at their sides and ends to create a spacious working area. They’re useful if you need to access a whole ceiling, for example for painting or electrical work. They can even be stepped, which is useful in places like cinemas or auditoriums.

SPECIAL REPORT TRAINING & UPSKILLING

RENEWABLE SKILLS Griff Thomas from GTEC, the Yorkshire based training centre specialising in renewables, urges installers to take up training in renewable technologies and make the most of the business opportunities that lie ahead.

I

n some respects, reluctance is understandable. A recent report by the Environmental Audit Committee (EAC) highlighted the impact of poorly administered schemes such as the Green Homes Grant on the take up of training; such negativity mustn’t be allowed to stall progress.

Installers need to embrace the fact that the UK is embarking on a green revolution and, with a little bit of training, they’re in a great position to deliver the goods, as well as benefit from a huge opportunity for business growth. The government could certainly do more to implement and fund installer training programmes to support its ambitious policies, but for forward-thinking tradespeople, there are some great opportunities out there, right now.

The government has promised 600,000 heat pump installations a year by 2028. At the moment we don’t have nearly enough installers to meet this target – there are only around 1,000 MCS certified heat pump installers.

Growing consumer interest Until recently, consumers have had very little choice when it comes to their heating. The vast majority are fixed up to the gas mains, others run their heating systems on oil. However, there are now viable alternatives to fossil fuels. End users are waking up to the fact that through a combination of new heating technologies and insulating materials their

“Installers need to embrace the fact that the UK is embarking on a green revolution and with a little bit of training, they’re in a great position to deliver the goods” homes can significantly reduce environmental impact.

Low-carbon heating isn’t just for newbuilds either – there are 27 million older homes and two million commercial and industrial buildings to retrofit. This is a staggering figure and without a significant increase in the number of skilled tradespeople we won’t be able to deliver the governments’ legally binding aims. In order to meet demand, installers need to be trained, qualified and accredited in a variety of low-carbon technologies to specify and fit heating solutions appropriate to the 21st century.

Looking back at the EAC’s report there’s a real fear that the current lack of trained and accredited tradespeople will jeopardise the heat pump installations the government has committed to.

HEATING BEGINS AT HOME

One of GTEC’s recent Air Source Heat Pump (ASHP) learners, Darren Jones, runs a plumbing and heating company based in Kirkby Lonsdale. Darren was impressed with heat pump technology, and on completion of the course, he installed an ASHP at home.

Darren said: “I’ve been interested in renewables for a while now. A lot of our customers live in the countryside and aren’t connected to the grid. At the moment they rely on oil, which is messy, smelly and unpredictable in terms of pricing. People are increasingly interested in greener options for heating; it’s really just a case of educating them – letting them know about the alternatives.

“I couldn’t very well extol the virtues of renewables whilst running my home on a gas boiler, so I decided to put my money where my mouth is and install an ASHP at home.

I honestly haven’t looked back. It’s brilliant – and so much more interesting than a gas boiler.

“The fact that I’m now running my home on renewables makes it a lot easier to persuade my customers to go green – and we’ve never been busier!”

drainage & water management

PLASTIC FANTASTIC Don’t let opportunity go down the drain, urges Richard Eddy, Category Manager for Polypipe Building Products

t has been 18 months since the introduction of the new Sewerage Sector Guidance, which was prepared to meet the requirements of Ofwat’s Code for Adoption Agreements was issued, and there are still some builders who are missing out on some real advantages that the new guidance brings.

The industry had been calling for a framework that allows for a more holistic approach to water management, and the new Sewerage Sector Guidance can pave the way for the design and installation of systems where above ground drainage and below ground drainage solutions can work closer in tandem.

The new mandatory code, including the Design and Construction Guidance, came into force in April 2020 and is subject to regular updates and amendments.

The framework has been put in place for the use of a greater range of below ground and above ground water

drainage systems, from the use of geocellular attenuation systems, to soft SuDS systems including natural culverts, water run-off systems and permeable paving, alongside the traditional use of large diameter pipe systems.

In addition, while the former regulations allowed water companies to vary requirements on products and systems deployed for drainage systems, the updated guidance ensures that all products and materials are evaluated by the same standards across England.

Importantly, there is an explicit instruction that the use of plastic-based pipes for below ground drainage can be considered on all sites. This means that there are now regions in England where house builders and developers can choose from a greater range of products and systems to suit their project objectives.

Plastic piping has always featured in sewer guidance, but new mandatory guidelines from Water UK, as approved by

Ofwat, state that all sewerage companies must adopt systems including plastic pipes and fittings, as long as they meet relevant product standards.

There are many advantages to using plastic pipes, but the key benefits are in terms of installation and reliability.

Plastic pipes offer ease of handling and robustness on site, the smooth internal bores facilitating superior flow properties, and the materials they are made from give great corrosion and chemical resistance.

Plastic pipes have consistently low leakage rates, and an excellent performance throughout the full life cycle.

Plastic pipes weigh a lot less than concrete and clay alternatives and can be up to 94 per cent lighter which has obvious advantages, such as reducing labour and machinery costs as often less

equipment is required for heavy lifting, and longer lengths mean fewer joints need to be made.

The flexible nature of the material means that it will be much less likely to fail due to earth movements, flooding and temperature changes and is less

susceptible to cracks and leaks than rigid materials.

There are long-term advantages to using plastic pipes beyond the initial installation – as is demonstrated by the fact that plastic pipes have been used in used in foul and surface water drainage systems for more than 60 years and are built to last for 100 years. They are also sustainable as they are 100 per cent recyclable at the end of life.

Builders now have more options in front of them to install a suitable drainage system and are able to draw on a greater

range of materials and products to develop solutions that meet the design specification of the developer and water company.

Focused on delivering solutions to the residential sector, Polypipe Building Products works with national and local developers, plumbing and heating engineers, general builders and groundworkers to deliver above and below ground drainage systems, rainwater solutions as well as hot and cold plastic plumbing products.

drainage & water management

If you are concerned about getting into deep water – use permeable paving. Jamie Gledhill, Brett Landscaping’s Engineering Technical Manager, examines the issue.

ON THE RIGHT PATH I n 2020, Water UK put pressure on developers to create more sustainable and resilient surface water drainage using SuDS rather than “end of pipe” solutions, such as balancing ponds or attenuation basins.One of the most effective methods for improving drainage without negatively impacting on land-use is the use of permeable paving solutions.

Permeable pavements work by replicating the drainage patterns of an undeveloped site where up to 95 per cent of rainfall is absorbed into the land, with only 5 per cent becoming surface water runoff. In this way the flow of water is attenuated, removing the early spike in surface water run-off, which creates the greatest risk and pressure on downstream water management.

Utilising the permeable blocks as both paving and the drainage solution, simplifies the process and reduces construction and environmental costs.

When compared to using balancing/retention ponds, it also increases the amount of land that can be used for building – as the drainage solution is simply part of the carriageway.

This, in turn, means that the housing density could increase.

Permeable pavements are also straightforward in terms of installation, the simplest of these being an infiltration system. Once the level of the sub-grade is chosen, a geotextile is laid before a permeable sub-base (4 – 20mm Coarse Graded Aggregate) is set across the area.

This is covered with a 50mm thick laying course (2 – 6.3mm Graded Aggregate) – before the permeable paving blocks are installed on top and jointed with the same 2 – 6.3mm aggregate. The normal flow of rainwater then evaporates within that system.

In the event of storms with high-

volume heavy rain, the permeable paving system will attenuate the surface water until the storm passes, and then slowly release the storm water back into the natural environment.

Research, in 2004, by the Construction Industry Research and Information Association has shown that permeable pavements can remove between 60 per cent and 95 per cent of suspended solids, and up to 90 per cent of hydrocarbons.

The research demonstrated that permeable paving systems are more effective in removing pollution from rainwater run-off than attenuation tanks.

The same research also showed that permeable pavements can remove a wider range of pollutants than oil separators.

This means that permeable paving effectively cleans the water as it goes through the system. Tyre residue on road surfaces causes a considerable amount of plastics pollution and ends up in the drainage system along with hydrocarbons, detritus, silts, microplastics. All of these pollutants can be captured by permeable paving.

Larger particles are stopped at the surface, while finer materials, hydrocarbons and heavy metals are trapped as they penetrate the supporting layers. Organic

materials, once trapped, break down over time, reducing the amount of contaminants that reach watercourses.

The result is that the water which infiltrates into the ground – or is drained to the next stage of a water management system, is of a much higher quality than if using an impermeable surface, relying on attenuation tanks. There are a number of other practical advantages to using permeable paving. Not least among these is that there is a greater range of products and finishes available across the market all designed with SuDS legislation and

system longevity in mind.

For example, Brett Landscaping’s residential permeable paving systems Omega Flow and Alpha Flow, with existing pavements still offer between 15 and 20 years of low maintenance service. There is also Brett’s new Invicta Flow which uses a blend of specially sourced aggregates to create new paving finishes, which are unique to Brett Landscaping.

The new Invicta range came about after a programme of significant investment and expansion of manufacturing capacity. This investment has allowed Brett to develop its

manufacturing processes to be able to blend the aggregates to create new paving finishes which are unique to Brett Landscaping.

Through this new AggTech process unique natural aggregates are used on the surface of each paving block to create a stunning durable finish. The Invicta Flow is available in four colours: Pearl, Moonstone, Onyx and Citrine.

REAP THE HARVEST Graf UK rainwater harvesting system has helped deliver on an eco-house dream t took until he was retired for Ian Loader to be able to fully embrace his green ambitions. When he did, it was with the help and support of Graf UK. The company’s Carat S rainwater harvesting system is a major element of the eco house Ian has created from a singleskin brick 1930s property that could not have been further from the green ethos.

The former sales director for a global commercial lighting manufacturer had been retired for six years when he and his wife Wendy downsized from a Grade II listed, five-bedroomed detached thatched house with outbuildings and extensive gardens in a village six miles outside Banbury to a four-bedroomed detached house 300 metres from Banbury Cross.

This much sought-after location was reflected in the purchase price, and it would have been uneconomic to demolish and build a new house, so the two-year process of turning it into an exemplar eco house began under the stewardship of main contractor CJ Charles & Sons, whose MD, Chris Charles, had built his own new eco house. The challenge was to apply the same criteria to an existing building.

Low energy design

As well as the Graf UK rainwater harvesting system, Ian’s low-energy design features include 120mm of internal wall and roof insulation, a bore hole ground source heat pump, 6.4kW photovoltaic panels on the roofs, triple glazing, a heat recovery ventilation system, LED lighting, a central vacuum

system and a 13kW Tesla battery in the garage to store the PV generated energy.

Electricity only is used for all services.

The Graf UK rainwater harvesting system was one of the first elements to be incorporated. It required a hole excavating in the front garden for the 4,800-litre Carat S ECO-Plus tank and then guttering on the house and garage to the tank, with ductwork from the tank to a small plant room, which delivers the harvested rainwater to the washing machine, toilets and garden.

“I did look at some other systems, but I wanted someone I could work with and the mix of German engineering with English standards of service impressed me. Graf’s prices were also very competitive,” he said. “We all have a responsibility to do something about the environment if we are able to, and luckily we were, because the Government can’t possibly provide all the incentives.”

The 2,280mm long Carat S ECO-Plus tank – which features patented filter technology and an in-house pump system with automatic switch-over to mains water supply – took two days to install into a prepared hole that was backfilled with

gravel on a concrete base. The associated ductwork took a further two days in the summer of 2019.

Ian and Wendy moved into their new eco house during a Covid lockdown in November 2020. Eight months later (July 2020) the tank is about half full. “We don’t have enough data to measure its full effectiveness yet, but we are very pleased that the system appears to be working perfectly. I think the Graf tank is a fine example of what can be done in a modest urban environment,” he said.

Preliminary consumption data from the water meter shows the household is using only 35 litres a day, which is substantially below the average for two people in a detached house. They estimate they will be paying £550 a year for all their electricity and £300 for their water (which includes water disposal), which bears “no comparison” to their previous very energy-inefficient home. In addition, the heat pump installation qualifies for a Renewable Heat Incentive (RHI) payment

over seven years that means the house will be more than cost neutral for the period of the payment.

Chris Charles said his company had installed many rainwater harvesting systems over the past 20 years and witnessed at first hand their evolution to being built off site and assembled on site.

“Graf’s system is in an easy kit form and is, in our opinion, now one of the best on the market. Graf staff are all pleasant and ready to help after a question is raised on site by the plumber or whoever needed guidance or could not follow the

instructions due to circumstances on site.

They were always ready to help.” He added: “At Ian’s house, it has been running for a year now, even before the clients moved in at the end of last year and has not given any problems.”

drainage & water management

THE ‘HOLE’ TRUTH John Rodgman, Managing Director at leading geotechnical drilling firm, Borehole Solutions, provides his professional insight into the benefits of rubble soakaways, and why the UK should be using them to manage excess water. ith notoriously wet weather and endless rainy forecasts, England is no stranger to the odd downpour. This rainfall is mostly manageable, but some facilities must take further action to enable suitable drainage in order to negate the threat of flooding. In fact, considering the shocking flash floods that devastated London over the summer, it’s clear that a quick and sustainable solution must be available to all those who may be affected by overwhelming weather. This is where a rubble soakaway can save the day, by transforming company efficiency, even when it’s raining.

W

What is a rubble soakaway?

Before diving into the benefits, it’s important to start with the basics. A rubble soakaway is quite simply a hole dug into the ground and - as the name suggests – filled with rubble and stone. This allows a gradual filtration of the surface water, back into the earth.

A pipe will run from the area where there is excess water into the soakaway.

This essentially acts as a roof gutter in order to help minimise the risk of flooding.

I

“Not only are they beautifully hidden, once installed, a rubble soakaway is also incredibly easy to maintain – so much so, in fact, that you can simply leave them alone to do their job.”

This is a highly efficient method of dealing with excess surface water – also known as run-off water – as well as being considerably more eco-friendly than alternative methods.

Low environmental impact

One hugely important benefit of the rubble soakaway, especially in the current climate, is its function as a drainage solution with a significantly low environmental impact. This is thanks to the very few materials and resources it takes to build one. A rubble soakaway

44 NOVEMBER 2021 PROFESSIONAL BUILDER

allows you to avoid the need for extra processing, or to add to the busy sewerage systems, as it will automatically filter the water into the necessary areas.

Further to this, the runoff water is far less likely to become polluted before permeating the ground, as chemical treatments are completely avoided prior to its return to the ecosystem.

Sustainable flood management

Rural areas typically benefit the most from a rubble soakaway. This is exclusively due to the fact that these areas tend not to

044_PB_NOV21_Layout 1 07/10/2021 10:59 Page 45

have storm drains, making flooding an increased threat. As we have seen very recently, however, flooding certainly isn’t exclusive to rural areas, and as such, neither are rubble soakaways.

These drainage solutions are frequently found in the gardens of suburban homes, particularly those suffering from waterlogged or boggy lawns. They also prevent standing water from building up against walls and causing structural damage to the home. Further to this, rubble soakaways hold huge appeal as they are virtually invisible once installed, meaning the aesthetics of your garden – or even a community area – will not be compromised. A highly adaptable and dependable solution for excess water; rubble soakaways are an absolute essential in any area prone to heavy rain.

Easy to maintain

Not only are they beautifully hidden, once installed, a rubble soakaway is also incredibly easy to maintain. So much so,

in fact, that you can simply leave them alone to do their job. It is, of course, advisable to check on the structure every few months or so, in order to ensure there is no silting or contamination. If installed correctly, however, this kind of soakaway should last for a minimum of 25 years, but in most cases, they will remain functional for a lot longer. Whilst easy to maintain, the leading issue that may affect the efficiency of a rubble soakaway is invasive plant roots, so aim to steer clear of any nearby vegetation.

When looking for the ideal anti-

flooding solution, look no further than a rubble soakaway. Making for a much more well-managed space when it comes to drainage, as well as being incredibly sustainable and low maintenance, this solution is ideal in any area, from the most rural setting to your own back garden.

QUESTION TIME Whether you are looking for a bargain used van or have a question about clean air zones, our resident expert has the answers you need.

Honest John Vans is the website that champions fairness for van owners by publishing expert, unbiased information to help builders make informed choices about their vehicles. Below is a selection of the most popular questions from www.HonestJohn.co.uk/vans

Q

Why isn’t my van showing on the insurance database?

Earlier this year I purchased a used Vauxhall Vivaro. It was advertised as having the 125PS engine which is backed up by a code on the door frame and the V5. When I try to get van insurance, it is coming up as a different model with a higher power output.

I do not want to be paying more for my insurance than needed or indeed, in the event of a claim, having it turned down due to inaccurate information. I have extensively trawled through my handbook but cannot find an answer. Can you help?

Gary (no surname supplied)

Q

What’s the best van for £1,500?

A friend is setting up a small business. He has about £1,500 to spend on a small van and will appreciate your advice on the best options taking into account road tax and insurance costs.

Andrew Bradshaw

I

The insurance companies get their data from the DVLA. It may simply be a database error or something more sinister in regards to the history of the van.

I would suggest taking it to your local Vauxhall dealer (ideally the one that sold the van when it was new) and get the VIN/registration and engine details confirmed.

You can then approach the DVLA and ask them to amend the database if an error is found or take it back to the seller and demand a refund if the history of the vehicle fails to add up.

A

He won’t get a lot for £1,500. Most vans in this price bracket are worn out and have the sky-high mileages to match. However, if I had to recommend a bargain-basement van, it would probably be the Mk1 Ford Transit Connect. It’s plentiful on the used market and has a good reputation for reliability.

A budget of £1,500 will get a 2007 or 2008 van that should give your friend a year or two of motoring, which should be enough time to get his building firm up and running.

Q

Should I buy a van with 164,000 miles on the clock?

I’m looking at a Renault Trafic van. It’s a 2011 model with 164,000 miles on the clock. It was previously owned by an engineering company and has a fullservice history. The dealer is located 300 miles away. Is this worth it or is the mileage too high?

Denver Margetson At 10-years-old and 164,000 miles the van will be heavily worn and require regular attention (and money) to keep it on the road.

What’s more, you’ll need to take it back to the dealer (300 miles away) to fix or address any faults that may develop.

However, if the van is in a good condition, there is no reason why it shouldn’t continue for three or four more years, with regular maintenance.

Q

My van isn’t exempt from the ULEZ charge. Is there anything I can do?

We have a company van (Vauxhall Vivaro 1.6 Bi-turbo, registered in March 2016). When we purchased the van from the main dealer in April 2016, he gave us the impression that the van would comply with the London Ultra Low Emissions Zone (ULEZ) – but it does not. Is there a cost-effective way to make this van comply with the regulations?

Richard Hart The ULEZ scheme allows for some vehicles to retrofit emissions reduction tech to meet the ULEZ standards, so it may be possible to adapt your van. However, be warned, the tech will not be cheap, and it may be cheaper to replace the van than adapt it to the Ultra-Low Emissions Zone standards.

Take note, the retrofit will need to be certified by the Government’s Clean Vehicle Retrofit Accreditation Scheme (CVRAS). The CVRAS currently has emissions reduction technologies certified for certain models of vans.

SMALL WONDERS

Good things really do come in small packages with the latest Yanmar Compact Equipment sub 2-tonne SV solutions. Professional Builder’s Lee Jones explores the new arrivals.

A

small machine it may well be but the mini excavator is doing big things in sales on these shores, and the 1-2 tonne segment is crucial to manufacturers. As a specialist in the field, Yanmar Compact Equipment believes it is best placed to understand its customers’ priorities and deliver the performance they demand. Indeed, Yanmar has devoted much time in listening to a diverse cross-section of its customer base, from contractors to landscapers and hirers, to understand what the expert end user actually wants – and the result is the new SV range.

Ask a mini excavator operator what they’re looking for in a machine and reliability, and ease of use is liable to be a predictable response, not to mention power and versatility. With its recent additions to the SV range Yanmar believes it has achieved all those requirements and more.

Diggers are now multi-purpose tools and a machine that can be configured to an individual operator’s needs is the ideal, and that’s one of the guiding principle of the brand new SV mini excavators – the SV15VT, SV17VT and SV19 VT. As an

I

explanation of the model designations the SV denotes Semi Vio – and a conventional short tail swing machine – whilst VT signifies a variable track, where the undercarriage retracts for access into confined spaces and expands to deliver greater stability. Finally, the numbers refer to the weight – 1.5, 1.7 and 1.9 tonne.

Range of options “We wanted to develop a solution that was not only productive but could adapt to the needs of a specific jobsite,” declares Cedric Durand, Marketing Director, Yanmar Compact Equipment.

“That’s why different versions of the same machine will be available – whether short or long digging arms and levelling blades,

50 NOVEMBER 2021 PROFESSIONAL BUILDER

for example, and a range of hydraulic options for attachments.”

The cab has been redesigned to offer 360º visibility, and more space, with ROPS, TOPS and FOPS certification for both the canopy and cabin variants. Once safely ensconced in the driver’s seat – thanks to the manufacturer’s ViPPS (Variable Displacement Piston Pumps) hydraulic set-up on the 1.7 and 1.9 tonne machine – operators are guaranteed to feel more power and control at their fingertips. The system cumulates the flow of separate pumps in order to obtain the optimal combination in terms of speed, power and balance, guaranteeing smooth and simultaneous operation of working movements. As a result, the machines can

050_PB_NOV21_Layout 1 07/10/2021 11:01 Page 51

achieve 53litres/min at 210 and 220 bar for the SV17 and SV19 respectively. In addition, on the 17 and 19 optional auxillary hydraulic circuits and quick hitch supply lines can be specified.

Yanmar is equally committed to delivering the simplest possible maintenance regimes for its customers. A wide rear hood opening – with all powertrain service points within comfortable reach – is complemented by easily removable side panels and a cabin floor that will allow access to all hydraulic systems and components. In addition, all three excavators benefit from the Japanese manufacturer’s fleet management system, SmartAssist Remote. As a result, a machine can be tracked via a PC or smartphone, and its health monitored in real time. As a brand Yanmar is rightly renowned for its diesel technology and this is exemplified in its Stage V-compliant TNV series mechanically-controlled 3-cylinder indirect injection engine.

Whilst the SV15VT is a rental ready machine, its larger sibling, the SV17VT has upgraded hydraulic performance and versatility, and the SV19VT is tailored to more demanding tasks. The latter’s short turning radius at front and rear, wide boom swing amplitude, and long blade increases the working range. Indeed, for easier cleaning and finishing, the combination of long arm and a levelling blade of extended length means the operator can easily push and collect soil with a ditch cleaning bucket against a blade. The SV19VT, also benefits from a digging force of 11.4/16.7kN (short arm/bucket) and

traction force of 12.9kN, with two travelling speeds – either 2.4 or 4.4km/h.

Manoeuvrable

Whether it’s trenching, light demolition, landscaping or repair, maintenance and improvement in residential properties, the extendable undercarriage provides a balance between compactness and stability. The SV15VT also has a light transport weight of just 1,465kg and 1,555kg for the canopy and cabin versions respectively. It can be easily towed between jobs with work tools on board, utilising a standard 2.5 tonne Gross Vehicle Weight (GVW) trailer. Four tie-down points on the track frames (standard) and four on the turning frame

(optional) make transport preparation simple. Moreover, a top mounted boom cylinder and hydraulic hoses routed inside the boom, as well as additional bucket and digging arm cylinder protection, will reduce downtime.

The SV15 is equipped with a double gear pump hydraulic system suppling 28.6 l/min at a maximum 205 bar pressure. This achieves a digging force of 7.4kN (short arm) and 12.9kN (bucket), while also coming with a standard auxiliary hydraulic line to power breakers or augers.

So, what have Yanmar’s customers been saying about the newly introduced mini excavators? More power and lifting performance has been the consensus, and, thanks to those extendable tracks, that’s complemented by enhanced stability, not to mention greater visibility and a working environment that puts the operator quite literally front and centre.

At the launch event the reveal for Yanmar’s SV Excavators began with former world breaking dancing champion, Ismail doing battle with a digger in the medium of dance, a fitting display for a highly compact and robust package that can perform on the most confined of urban jobsites.

vehicles & plant 씱 Daniel Took, Head of Product at Kärcher UK discusses the best practices for cleaning construction machinery to a high standard.

Clean machine onstruction machines are exposed to huge quantities of dirt during operation.

Whether on site or off-site, cleaning measures play an important role in preserving functionality and retaining value as well as acting as a precondition for maintenance and repair. Clean operating equipment is also essential for protecting employees and ensuring workplace safety. There are a range of cleaning methods that can be utilised to protect machines from cold- and hotwater high pressure to dry ice blasting.

Cold-water high pressure on-site: Whether dump trucks or diggers – construction machines take a lot of punishment but need to remain fully operational. To ensure this, intermediate cleaning on site is essential. For fast and efficient cleaning, cold-water highpressure washers are ideal; removing dirt from chains, shovels or wheels without the need for cleaning agents. A robust design enhances the pressure washer’s portability allowing them to be easily

C

transported around the site on pallets or by crane hook depending on where the machines are located.

When selecting the machine, it must be ensured that, in addition to sufficient pressure, it offers a flow rate of at least 1000 l/min. The larger the flow rate, the higher the amount of water coming from the pressure washer aiding the removal of

large quantities of dirt. The water supply can be provided via a mains connection or a tank on location, or by means of a high-pressure trailer, depending on the machine and local conditions. In addition, it must be decided whether an electrically powered model is appropriate, or versions with a diesel or petrol engine.

To achieve the desired delivery rate, various nozzles are available as accessories. Flat jet nozzles are designed for removing coarse dirt from surfaces – for example on shovels or trailers. If hardened dirt must be removed from a small surface, a point jet nozzle is more

vehicles & plant

suitable. Rotation nozzles combine both functions as they can be rotated to alter the nozzle depending on what is required.

Hot-water high pressure off-site: When machines are off-site or returned to the firm, deep cleaning is essential before any maintenance can be done.

Stationary installations set up as wash bays equipped with hot-water highpressure systems are ideal for achieving a faster cleaning result.

If oily or greasy dirt is involved, a cleaning agent can be used to reinforce the quality of clean at the wash bays.

Here it is important to use a separatorfriendly cleaning agent to separate oil and grease from the excess water. This process allows the water to be treated appropriately and in accordance with local restrictions and guidelines.

Using dry ice blasting: High-performance machines with small components, electronic circuitry or sensitive hydraulic systems are best suited to cleaning with dry ice. Dry ice cleaning can only be done off-site, but it allows for an effective and gentle clean without residue waste.

Dry ice blasters apply compressed air to accelerate the up to 3-millimetre-large dry ice pellets to over 150 m/s. The dirt is frozen at a temperature of -79 °C and becomes cracked so that it can be removed effortlessly. Furthermore, the dry ice penetrates even the tiniest nooks without the need to remove components, and no residues remain after the cleaning is completed.

Removing wastewater: During the cleaning of construction machines, large quantities of dirty water are often produced. It is important that this water is disposed of correctly, particularly if oil escapes from the

hydraulic system during the cleaning and gets into the wastewater. During all work it must therefore be ensured that local sewage law and the regulations on water treatment are respected. At wash bays in firms, oil separators must be installed.

Selecting the right type of cleaning based on the machine and its location is a key step to protecting the longevity of construction machines and retaining their value. Ensuring a safe working environment and clean equipment will go a long way to maximising performance in the long run.

GIMME FIVE! JCB has taken the opportunity to introduce a number of new features to its Stage V mini excavator portfolio. Professional Builder’s Lee Jones finds out more. hen it comes to JCB’s latest mini excavator entrants in the 4 – 6 tonne bracket, operators will welcome the emphasis on lower overall cost of ownership, return on investment, intuitive operation, maximum uptime and strong residual values. The revamped Series 2 Stage V models – the zero-tailswing 50Z-2, 56Z-2 and the conventional tailswing 60C-2 – share the same engineering DNA as their already popular predecessors, but with some significant upgrades.

All three are powered by a 1.7 litre, turbo-charged three-cylinder Stage V Perkins engine, delivering 34kW or 45.6hp. Thanks to Diesel Oxidation Catalyst (DOC) and a Diesel Particulate Filter (DPF), there’s no need for a diesel exhaust fluid, such as AdBlue. The engine has been matched to the hydraulic systems, with the further adoption of programmable auto stop, programmable auto idle, and a one-touch idle function.

Moreover, the patented hydraulic system operates with reduced back pressure, reducing fuel consumption, and eliminating parasitic losses. In addition, thanks to a system where the engine RPM automatically drops below the idle working speed when the arm console is raised, fuel is conserved further still.

W

The Series 2 units benefit from a larger ROPS cab and the increased visibility that a revised front screen affords. There’s Bluetooth with hands-free capability and a 7in. colour screen provides programmable auxillary hydraulic flows in both low and high flow settings at the command of a driver’s fingertips. These can be set for up to 10 attachments, reducing downtime when swapping between work tools.

At the controls

Rather than introducing another screen into the cab, an integrated rear-view camera can be routed through to the main display, whilst plenty of leg room is complemented by tracking pedals that have been redesigned so that the machine can be tracked forward when the operator’s heels are on the floor.

In transportation, there’s four tie down points on the undercarriage and a further

four on the upper structure, and a fully bushed kingpost delivers increased durability, whilst there’s 500 hour greasing on all the pivot pins, and a 5year LiveLink subscription.

Two meet growing customer demand in the 3.5tonne class, the Staffordshirebased manufacturer has also added the 36C-1 conventional tail swing and 35Z-1 zero tail swing to its mini line-up. The former is an entirely new addition to the compact portfolio and JCB is promising improvements in reach, stability and lift performance, whilst the 35Z-1 is ideal for operating in restricted spaces. Both are powered by a Stage V three-cylinder Stage V/T4 Final Perkins engine, delivering 18.4kW (24.6hp), again with no need for a DPF, and the 35Z-1 and 36C-1 also share the same new ROPS/TOPS operator space – available as a canopy, a cab with heater, or a cab with air conditioning.

The cab includes Bluetooth radio, a 12V socket and two USB ports for mobile phone charging. There’s also an immobiliser to prevent theft and JCB LiveLink telematics system is included.

GetMyEquipment is streamlining the sourcing of tools and machinery on the most cost-effective terms with a new web-based platform for equipment hire that benefits both suppliers and builders.

GET TOGETHER

uring the course of the pandemic digital tools would emerge as our saviour, allowing business to maintain vital channels of communication in an age of social distancing. As society returns to some level of normality construction is now well placed to embed these technologies into its processes and enjoy the efficiency gains they promise.

“We started from a position that construction has often been a laggard in digital transformation,” explains company founder, Stephen Lewin. “It has as a result fallen behind in terms of productivity and output, and we believe we can do our bit to help. The equipment hire industry, for example, is one of the most fragmented sectors of the economy, with hundreds of thousands of building firms and thousands of rental companies operating in a pretty traditional way.”

Time saving

In that environment, time poor tradespeople, find it difficult to source the best deals from the most reliable companies, whilst tool and plant hire firms struggle to develop new customers.

GetMyEquipment is designed to bring both parties together on a more equitable basis, and match supply to demand. So just how does it work?

“GetMyEquipment is an online marketplace that’s focused on the local jobbing builder – as well as medium sized contractors and subcontractors – and we’re purely business to business with no DIY customers. Similarly, when it comes to equipment stockists, we’re targeting independent local and regional players. The online interface itself is designed to be very user friendly. A builder will register with our site, input what equipment they will need for a particular job and an enquiry goes out to the suppliers in that area. Quotes from suppliers are ready

56 NOVEMBER 2021 PROFESSIONAL BUILDER

in a few minutes and the customer can then compare what equipment each company can supply, the pricing, and how they have been rated by other users in terms of service and the quality of the kit.”

Rather than managing multiple accounts, or resorting to the supplier they know, and risk missing out on a more cost effective and reliable alternative, GetMyEquipment enables the contractor to do business through just one online platform. Once they know who has availability, it’s a simple question of ordering through the click of a button, and the machinery is delivered.

“Builders can either complete the transaction as a cash customer, making use of an online payment portal to pay by card up front, or as a trade customer, with a 30-day trade credit arrangement, and would then be invoiced by the supplier accordingly. We’re an online marketplace, so the contract is between the construction company and hire firm, which means that the stockist does not have to change their own practices or terms and conditions in any way – the existing contractual obligations remain the same.

056_PB_NOV21_Layout 1 07/10/2021 11:03 Page 57

For a small hire firm with perhaps only one or two depots, one of the big advantages is that it makes their fleet and equipment catalogue immediately more visible to a wider range of customers, enabling them to compete for business on a local basis with some of the big names in the sector. It increases their presence without any additional costs.”

Full range

Through GetMyEquipment builders can source anything that’s required for an individual project from excavators, access equipment and welfare provision to handheld power tools. Moreover, if a construction company is working away from home, and outside the catchment area of their regular suppliers, the website becomes a very useful tool in finding stockists in any given location.

Stephen and his team have also thought very carefully about security issues. Before registration to GetMyEquipment is approved, for

instance, a contractor is thoroughly vetted, to ensure that they are a viable business, and when the hirer receives an enquiry they will be provided with all of the customer’s details so they can conduct their own standard checks.

Registration for building companies and hirers is completely free, with GetMyEquipment charging hire companies a small commission on the overall value of the transaction.

With the help of a £100,000 grant from Innovate UK, GetMyEquipment was launched to the market in Spring of 2021, initially in London and the south east, and has been steadily growing its customer base since then. “We believe that the industry is desperate for this kind of digital transformation,” concludes Stephen, “and GetMyEquipment is designed to help companies on both sides of the plant and tool hire business.”

LOCKED & LOADED Professional Builder’s Tibby Singh visits Locks 4 Vans (L4V) and gets an insight in the company’s huge range of vehicle security solutions

U

nfortunately, van crime is something that will always be with us. I wish I could say it would end tomorrow but, in reality, it won’t. Criminals are opportunistic, so if they see a vulnerable looking vehicle, it becomes a target. The only way to eliminate or reduce the risk of this, is the installation of additional security to the van. This is where Locks 4 Vans (L4V) provide aftermarket security solutions to the problem. At the end of the day the tools of a tradesperson are their livelihood. Taking that away from someone is devastating and has massive implications from financial to even affecting their mental health and wellbeing – because if you don’t have the tools you simply can’t work.

We were privileged to be invited to the Locks 4 Vans HQ where the team gave us a tour of the facilities and talked us through the manufacturing process of

I

the company’s various security systems. I was surprised to learn that L4V currently offers over 7,000 locking and shielding products/components to cater for all. This makes sense as there are so many different vehicles, makes, and models – hence such a large product range. Even if it’s not available they are able to quickly and efficiently produce bespoke products if required. We were particularly impressed with how quickly they can respond to demand, with prototypes being made within days of a need being highlighted. This could simply be due to the introduction of a new van, with a new security system then needed. A vulnerable area of a van could also have been identified, which means a

rapid response is required, because the longer the product is delayed the greater the damage could be inflicted.

Best seller The UK’s best seller is the L4V Hook Lock, which can be fitted to a cab, side or rear door. It works completely independently of the manufacturer’s locking system, so if they get past that there’s another obstacle.

058_PB_NOV21_Layout 1 07/10/2021 11:04 Page 59

Tibby Singh - www.TibbySingh.com

This is available for all manufacturers and models and has the option to be fitted at high, medium and low positions. One of my concerns was if a lock’s being fitted inevitably a considerable amount of metal would need to be removed, so does that weaken the door? However, 60 per cent less metal is removed from the structural part of the door during installation compared to other hook lock cases, making Locks 4 Vans the right choice. The L4V Deadlock is similar to the Hook Lock but here the lock engages a ‘straight bolt’, making it suitable for cab doors, whereas the Hook Lock may be better suited for sliding doors.

Slamlock Another product that will slam the door shut on thieves is the Slamlock. This is perfect for anyone who is regularly in and out of the van, because as soon as you close the door it locks and can only be opened using the L4V Slamlock Key. So, if you’ve got your hands full, you don’t have to worry about messing around with the keys, which is handy. A Slamhandle is also available, which works in the same way, but incorporated into the handle is a powder-coated stainless steel replacement handle, providing an upgrade to security.

The solution that stood out for me was the Statement Lock. Not only is it a visual deterrent, but also a practical one too. This mounts externally, bracing the two doors together, and is usually fitted higher on the doors to protect against the ‘peel and steal’ method of forced entry, although vehicle specific Anti-Peel Kits are also available.

Another convenient provision is the key

matching service, so you don’t have the hassle of different keys for different locks, the added weight and hassle of working out which key is for which lock.

Brace yourself as it doesn’t end there; L4V provide so much more with just some of what on offer listed here: 씰 Ford Replacement Lock 씰 Ultimate Lock 씰 Heavy Duty Shutter Lock 씰 Narrow Slat Shutter Lock 씰 Cargo Lock 씰 Eternal Shielding 씰 Handle Shields 씰 Internal Latch Shields 씰 Loom Guards 씰 Cat Guards 씰 Spare Wheel Protectors 씰 Interior release Guards L4V’s passion to reduce van crime is evident by its actions. For example, the security specialist has recently invested £2.5 million to extend its capabilities with a further research and development facility. Thieves like to think if one door closes another one opens, whereas L4V are always ready to react and take the appropriate actions. Although much of their work is understandably reactive – after incidents occur – they try to be as

proactive as possible, anticipating what may be the next target to stay ahead of thieves. An example is the increase in electric and hybrid vehicles, which will play an important role in a greener future, but they are still on the criminals’ radar. L4V also offers an extensive and growing range of products to secure these next generation vehicles.

Nothing is bullet-proof, of course, but having additional security will delay someone trying to break into the van by a considerable margin. They will need some serious equipment to gain entry and with that comes noise. In that time, they will hopefully be caught, defeated or deterred and flee the scene. To have this additional layer of security in place gives me a piece of mind. It’s also perfect for someone who travels for work like myself. More recently I’ve been travelling around filming for Changing Rooms which meant stopping at various hotels in unfamiliar locations or even in the middle of nowhere. Their continued innovation puts you at ease and would always suggest getting extra security; ‘Act, Don’t React’!

The new Nissan Townstar features petrol and fully electric powertrain options

VAN ABOUT TOWN s a manufacturer, Nissan has been charging ahead with electric models for some years now. Indeed, its eNV200 was one of the early pioneers in the sector and its new compact light commercial vehicle, the Townstar, continues in that tradition – but with the addition of a fuel-powered option. Not only that, but the manufacturer is claiming no less than a suite of 20+ new technologies across the Townstar portfolio, as well as a versatile range of configurations.

The fully electric version features a 44kWh battery and, as such, is a solution in sync with tougher emissions standards and the onward march of urban low emission zones. The new van will offer 245Nm of torque and 177 miles of range – a 43 per cent improvement over the outgoing e-NV200. Alternatively, a 1.3-litre petrol engine model will be available, which is fully compliant with the latest Euro 6d-Full emissions regulations and produces 130HP and 240Nm of torque.

A

Versatile solution

For a tradesman the business end of any van is the load bay and the Townstar offers up to 4.3m3 of space, with 800kg of cargo capacity. That area is accessed by large sliding doors on the side with the

I

option of 60/40 French doors with 180degree opening at the rear. There’s also a suite of smart storage solutions and a dedicated space for on-board office tools.

For anyone transporting plant or equipment by trailer there’s 1,500kg of towing capacity on offer.

Safety first

Amongst those aforementioned technologies, safety and driver assistance features very prominently. Side Wind Assist and Trailer Sway Assist, is joined by Intelligent Emergency Braking featuring Pedestrian and Cyclist Detection and Junction Assist, whilst there’s also HandsFree Parking and Intelligent Cruise Control.

Moreover, in a first in the compact van

60 NOVEMBER 2021 PROFESSIONAL BUILDER

segment, Nissan is integrating its Around View Monitor (AVM) solution into the Townstar. Using a system of cameras, a 360-degree overview of the area around the vehicle is displayed to the driver.

When behind the wheel builders can also enjoy the ProPILOT advanced driver assistance system. Supporting motorists with highway driving, the feature allows the vehicle to automatically slow to a full stop and accelerate by following the vehicle ahead, as well as keeping it centred in the lane – even around a gentle curve.

Elsewhere, connectivity is covered with E-Call, Apple CarPlay/Android Auto, and wireless phone charging all of which are accessible via an 8in. touchscreen, which

060_PB_NOV21_Layout 1 07/10/2021 11:09 Page 61

in the fully electric all-new Townstar is linked to a 10in. digital combimeter in front of the driver.

The Townstar is the latest vehicle to be introduced under the Nissan NEXT transformation plan, which prioritises sustainability. It’s also solution that has been specifically targeted at SMEs, and those operating in urban environments where a compact unit will come into its own. In that context, builders will welcome the combination of space and cargo capacity with features that include a hands-free parking system for complex city parking.

Much of the Townstar’s styling, including the seat and door trims, centre console and instrument panel, are derived from the same manufacturer’s Ariya electric crossover, and reflect inherent passenger-car-like comfort as a consequence. That’s a theme that continues through the signature standard LED headlamps and an aerodynamic front shield integrating an Kumiko pattern and a V-motion design with daytime running lamps.

Likewise, the petrol version stands out with an interlock grille and “air-curtains”, which optimise airflow around the front bumper and front wheels, reducing drag and improving fuel consumption.

5-Year warranty

Nissan owner operators can benefit from a 5-Year or 100,000-mile warranty, in addition to the eight-year or 100,000-mile battery warranty for the EV version. This includes bumper-to-bumper protection, paintwork guarantee, genuine parts and accessories and roadside assistance.

REPAIR TAPE

TO THE RESCUE! You’ll find any number of uses for Bond It Rescue Tape and if you send in a picture of your own example you could win £500!

Not only is this self-fusing silicone repair tape a solution to stopping leaks but it also has many uses in and outside the home that you may never have thought about. Silicone Rescue Tape can be used for 1,000’s of applications. From emergency repairs to electrical wiring and waterproofing.

A quick description: Rescue Tape is silicone and sticks to itself – well, actually, it fuses to itself – when wrapped around an object. The tighter you pull it, the better the seal. It’s great on hoses and plumbing and unlike electrical tape, it won’t get gummy, and it won’t dry out like duct tape can – even in the sun.

This waterproof repair tape seals live leaks on pipes made from copper, PVC plastic, steel, malleable iron, and many other materials. Ideal for fixing leaks in applications ranging from small domestic plumbing problems through to large scale industrial pipe repairs, it avoids costly and disruptive shutdowns of systems. The versatility of the product makes it suitable

for wrapping hoses, and other types of pipes, and can also be used as an electrical tape with insulation protection up to 8,000 volts.

It is easy to use and, depending on the size and pressure of the pipe, repairs can be carried out in under 15 minutes. The tape stretches by three times its length and, once applied, it fuses to form a solid rubber band which exerts maximum pressure over the hole or crack in the pipe. Using multiple tapes creates a repair which is pressure resistant up to 8 bar and is temperature resistant up to 260°C. You wrap it around an item, and overlap it by 50 per cent, pulling tight – stretching it to at least double the length – and going 3 to 5in. on both sides of the leak (not necessary for things like rigging, chain marking, line whipping and so on where there’s no leak). That means for a 1” split in a hose, the total repair is going to be 7 to 11in. long! The tighter it’s wrapped, the faster and stronger it will fuse. For high pressure leaks, you may

need to put a second layer on, but the result will be water-, fuel- and air-tight.

Consider it permanent, too – if you need to remove it, you’ll have to cut it off.

The tape has no adhesive so there is no sticky residue like regular electrical insulation tape, so you can’t accidentally stick it to things you don’t want it to stick to, which also means items can be repositioned easily to get the perfect bond, and the uses are only limited by your imagination.

’ L I OIN A ‘DAY’S WORK

A specialist cutting oil has been heralded as a game changer for carpenters…by a carpenter “That’s going to extend the life of my saw blade…” was the excited verdict of a carpenter specialising in building wooden decking when handed a can of Multi-Purpose Cutting Oil from WD-40’s Specialist range.

Like so many tradesmen and women, our ‘chippy’ friend is a seasoned user of WD-40 Multi Use Product, and one of the many roles he uses it for is constantly spraying liberal amounts on to his circular saw blade to help it slice through the endless 3x2s, 4x4s and not forgetting the countless 6x1-in. thick decking planks that challenge him.

His idea being that the lubricant ensures the neatest of splinter-free cuts to ensure a true professional finish and, because of the ease of cuts, WD-40 MUP extends the life of his blade.

The only ‘issue’ with MUP – if you want to call it a problem – is that it runs straight off the vertical blade or evaporates, a process that is speeded up the moment it’s fired into action and said blade spins at thousands of revolutions a minute...

But that’s where Multi-Purpose Cutting Oil comes in to its own. Its properties ensure the solution ‘sticks’ to the blade for far longer, ensuring a precise and easy hot-knife-through-butter cut time and time again.

To test our carpenters’ theory, we replaced his blade with a new, mid-range one costing £24.99 at the start of a week-

long build that included a raised frame made from treated 5x2in. joists mated to sturdy 4x4in. posts, intricate steps and two deep planters. As our carpenter was true to his trade, he opted for cutting joints rather than using metal braces and brackets. To further test the theory, we opted for the harder Siberian Larch decking planks and capped it all off with a half pagoda.

By rights, our carpenter would have been reaching for a new blade at the end of the frame-build to ensure the neatest of cuts to his decking planks, particularly as the Larch is as expensive as you can arguably get for decking.

But, true to his theory, a regular dose – and with that we mean every fourth or fifth cut rather than every single time the

saw is used – of Cutting Oil ensured a single blade was used for the entire job, and then two further projects before there was a hint of ware. Significantly, too, is the fact less than a third of a can of WD40 Multi-Purpose Cutting Oil was used in the process.

“I’m completely stunned.” That was the summary of our carpenter: “while I knew WD-40 produced Cutting Oil, I’ve never given it a second thought but it really is a game changer for me.

“The fact it stays on the blade longer really does help the saw to cut through wood with complete ease. The finish is far sharper lines and a blade that has lasted me three times as long as I’ve previously experienced.”

Professional Builder’s Tibby Singh is ‘Quik’ on the uptake with Simpson Strong-Tie

Simpson Strong-Tie has been going strong for over 60 years and if you’re a carpenter you’ve inevitably used the manufacturer’s connectors from either joist brackets or wall ties. The company provides more than 1,000 products and offers the widest connector range in Europe.

What I didn’t know was that Simpson Strong-Tie also supplies a range of Quik Drive Tools, for various applications, a range of screw sizes and different materials. It certainly makes sense to provide an adaptor to complement the fixings, which then makes for a complete system.

The QD76KE Multi-Purpose

I

Attachment is suitable to drive screws ranging from 25mm to 76mm in length. The future of screwing into plasterboard, flooring, decking and other applications is the collated screwdriver system. This innovation is a significantly faster way to install screws, and that’s exactly what this Quik Drive adaptor does – it converts your drill into a collated screwing system.

This is an adaptor that goes onto the end of a drywall driver, and it’s a simple system with only a few set-up steps. Firstly, there is an option to purchase the Quik Drive with a drill, which will include all the correct adaptors. However, if you opt to get the system separately all you need to do is remove the nose cone and bit holder and replace it with a Quik Drive adaptor made for the screw gun.

Then it has a mandrel, which is a long bit holder, and you’ll need to ensure you have the correct bit in. Normal bits cannot be used, as these lock into position ensuring they won’t fall out.

Don’t worry, you won’t need any additional tools to take the bit out, because there’s a release key located on the side of the auto feed attachment. So, you won’t be losing that either.

Once the mandrel is inserted, you simply slide the auto feed attachment and snap it into place. It allows you to turn the attachment 360 degrees for a personalised comfortable setting. So, it really is plug and play. Depth adjustment is covered with a wheel located at the top of the attachment.

It’s cleverly designed to lock into place, which provides the assurance that it’s not accidentally going to change position.

Inserting the strip of screws into the

68 NOVEMBER 2021 PROFESSIONAL BUILDER

auto feed attachment is very much akin to any other system, but you may need to change the nose piece at the end depending on the size of the screw. This is just a twist and pull system so, again, nothing complicated. I must mention that this attachment is incredibly low maintenance and in fact it doesn’t require any maintenance because it’s manufactured containing PTFE which reduces friction and has non-stick properties, meaning no lubrication is required either.

Screwing into floors can be a ponderous task and I don’t know anyone who loves to be on their hands and knees all day long and that’s certainly not good for your back or knees. Quik Drive has your back covered, because it also has an extension pole that can be attached to the drill in the same way. This improves ergonomics with massive health and safety benefits. I expected this to be big and bulky, but it’s very small in diameter which also helps with accuracy when screwing. It also has a handle which can be locked into various positions for your own comfort.

WORKWEAR

Peter Dumigan, managing director of the Hultafors Group UK, explains how sustainability and climate control working clothes are coming together to create a better on site experience

‘WEAR’ CREDIT With firms and individuals increasingly focused on environmentally responsible business activities, Snickers Workwear’s eco-friendly garment solutions could prove to be the right ‘sustainable choice’ for you and your business. For example, with government legislation on the horizon, employing the Snickers Workwear garments made from recycled polyester, organic cotton and muelsingfree fabrics as well as the ‘100% Circularity’ in EMMA safety footwear, will deliver peace of mind and compliance in an increasingly demanding world.

This socially responsible approach to kitting out professional tradesmen and women is complimented by the brands’ hallmarks of comfort and functionality.

They’re delivered through the use of climate control and stretch fabrics which ensures that, whatever the size of your workforce, there’s a product to fit each individual perfectly – for improved wellbeing and performance at work.

I

IS DUE

Our climate-control clothing is tested for real from the Arctic Circle to the southern Mediterranean in extreme environmental conditions – cold, heat, wind and rain. But not only are these working clothes tested for performance, they’re now tested with regards to ‘Environmental Sustainability’. As a result ergonomic body mapping designs are combined with fabrics that include the latest in recycled, organic and sports fabric technology, delivering winter warmth and cooling comfort when you need it.

The upgraded lightweight and breathable 37.5 fabric technology in the LITEWork and FLEXIWork mid- and baselayer clothes feature cooling technology.

TACKLE IT

No.5

WITH When holes and small gaps appear in a roof, time is of the essence to repair the damage and prevent water from seeping – or in a worst-case scenario pouring – into the structure and causing internal damage. Our Emergency Roof Seal is designed to immediately fill and bridge small gaps and holes for a tough, long lasting and watertight repair.

Next up in our series with Thompson’s, Technical Services Chemist at the company Chris Fletcher is running through the applications and benefits of Emergency Roof Seal.

HOW TO APPLY IT It’s incredibly versatile and can be applied on all types of roofing including felt, asphalt, slate and tiles. Before applying this product, it is important to make sure the surface is clean. If it is raining, brush away any ponded water around the area of the repair – and if it is dry, remove any dust, dirt or debris with a stiff bristle brush. If needed, always repair any structural faults before application.

Emergency Roof Seal should then be applied in a thick layer over the problem area. It gets to work immediately and can dry within 24 hours for an incredibly quick fix. Once the job is done, always make sure that you clean equipment immediately by removing as much product as possible before cleaning with white spirit. As a solvent-based solution, it is important to contact your local authority to find out how to dispose of product safely.

YOUR CHANCE TO WIN!

Thompson’s is giving five lucky winners the chance to get their hands on a prize bundle including a Makita MR052 Cordless Radio and some Thompson’s goodies. To win, use the rdr.link below to visit the Professional Builder website and answer the following question correctly: Q: CAN THOMPSON’S EMERGENCY ROOF SEAL BE APPLIED WHEN IT IS RAINING? A: YES B: NO To enter visit the Professional Builder website by using the link: WWW.RDR.LINK/BAA085

KEY BENEFITS? The fast-acting formula means it offers an instant repair – so professionals can quickly and easily fix a leaking roof and immediately stop water from getting into the structure and causing lasting damage. One of the key benefits is the ability to be applied even when it is raining. Its formula makes it highly water repellent, which means that no water can get into the product and disrupt the curing process. What’s more, it is a thick substance, so it won’t wash away.

There is also no need to use a mesh as the formula includes microfibres that give it extra strength, speeding the application process up even more.

The Seal also has a level of flexibility so it can flex with natural structural movements without cracking or breaking, ensuring a long-lasting result. However, it is important to note that it is not suitable for walking on and should, therefore, only be used as a temporary fix for leaks on balconies or accessible flat roofs.

PITCHED ROOFING

TECHNICAL TEAM TIPS – NO 31

PITCH IN AND HELP Marley’s technical team answers some of the common pitched roofing queries from contractors.

Advice from underlays and ventilation, to installing the increasingly popular solar PV solutions, here’s five of the most common technical queries from the past few months: What does a full roof system include?

A full roof system should include your roof covering, e.g. tiles or slates, in addition to battens, underlay, fixings, dry fix and ventilation. Our full roof system also comes with integrated solar PV and fire barrier as an option. Sourcing a full roof system from one manufacturer offers several benefits, including guaranteed quality and compatibility, compliance with British Standards, technical support and ours also offers a 15-year roof system warranty.

Q

The innovative technology gives the benefit of an increase in total power output from the roof area or achieving the same output using fewer panels. A higher power rating makes roof-integrated solar a more cost-effective option, with fewer panels and roofing kits needed to reach the required energy target.

Can you provide an estimate for solar PV? Our solar configurator, which can be found on our website, helps you to build a solar array, making pricing jobs and calculating panel performance simple. It also includes an energy calculator tool, which will help demonstrate to customers how much they can expect to save on their energy bills by installing solar.

For more information on the Marley Solar Configurator visit

Q

WWW.RDR.LINK/BAA087

How much power do your solar panels provide?

With the growth in demand for renewables, many roofing contractors are looking to expand their offer to include PV installation.

That is why we have just launched a new integrated solar panel. The enhanced Marley SolarTile is quick to install, and the increased efficiency allows for an install time of just 45 minutes per kWp.

Q

I

What type of underlay should I use?

There are several design-related considerations including whether it is a warm or cold roof, type of roofing product, how well sealed the ceiling is, size of roof and what wind zone it is in.

There are two main types of roofing underlays: high resistance (non-breathable underlays) and low resistance (breathable or vapour permeable membranes).

For many years, traditional roof constructions have used non-breathable underlays in conjunction with low level (eaves) and high level (ridge) ventilation systems. This traditional approach is both effective and proven.

Newer, breathable membranes come in two different types: vapour permeable and vapour and air permeable. Breathable

Q

76 NOVEMBER 2021 PROFESSIONAL BUILDER

underlays are generally more expensive than their non-breathable counterparts.

However, they offer several other benefits in that they’re lightweight, durable and easy to install, and provide some supplementary advantages when it comes to roof ventilation.

However, don’t rely on a breathable (LR) underlay as the sole means of ventilation. BS 5250 continues to recommend ventilation of the loft space and sometimes the batten space, and so our recommendation is that roofs will always require some form of supplementary low, high or both, levels of ventilation, regardless of what underlay is used.

What is the best way to provide roof ventilation?

Despite misconceptions, breathable underlays should not be solely relied upon when installing clay and concrete roof tiles and additional roof ventilation is also recommended. This can be achieved using eaves ventilation, ventilated dry ridge systems, ridge vents or multiple tile vents to provide the recommended minimum ventilation in accordance with BS 5250. Ensure you are following the new version of this Standard, which was launched at the end of July. See our latest blog for more details

A ROCK AND A GLASS PLACE

NEW

SERIES

Knauf Insulation continues to look at what products are required for the right application When deciding whether to use Glass or Rock Mineral Wool, Bradley Hirst, Technical Services Manager from Knauf Insulation, explains that you need to take performance and application into account.

Thermal performance If thermal performance is the primary consideration, such as when insulating masonry cavity walls, choose Glass Mineral Wool. Some products can achieve a lambda value of 0.032 W/mK, compared to a best of 0.034 W/mK for Rock Mineral Wool.

Fire safety Mineral Wool is non-combustible under the Euroclass reaction to fire classification system, so will not contribute to the development or spread of fire, making it the safest option at any height.

Where fire resistance is required, such as in the separating floor of a loft conversion, Rock Mineral Wool is more suitable. With a melting temperature of over 1,000ºC, it minimises heat transfer giving occupants time to escape.

Always choose products developed and tested for fire resistance.

Noise reduction Mineral Wool is the best insulant when it comes to absorbing sound. Many people believe Rock Mineral Wool performs better than Glass Mineral Wool because of its higher density.

Our tests show that both perform equally well in real world buildings.

Robustness Rock Mineral Wool has superior compressive strength than Glass Mineral Wool. This makes it suitable for use in applications such as warm flat roofs where robustness is required.

Comfort Another consideration is installer comfort.

Mineral Wool products manufactured with ECOSE Technology, Knauf Insulation’s unique bio-based binder, contain no added formaldehyde or phenol. They are soft to touch, easy to handle, generate low levels of dust and VOCs, and have been awarded the Eurofins Gold Certificate for Indoor Air Comfort. Knauf Insulation’s Glass Mineral Wool product range has also been accredited as DECLARE ‘Red List Free’ label. This provides a straightforward ingredients list, together with information about embodied carbon and product life expectancy.

ADE’S TOP DOORS & WINDOWS TIPS

No. 31

A HA’PAH OF TAR...

Quickslide’s Ade There can be no compromise on a quality installation, insists

Now and again we are asked by trade customers to change the basic specs of windows and doors, perhaps because they are trying to shave a bit off the cost, or because one of their punters has decided that they don’t like the look of something, such as trickle vents for example.

When this happens, we push back with advice that recommends why such things are in place and that actually, the difference between doing it right and doing it wrong usually doesn’t represent a great deal of money. However, often something is included because it’s a requirement of the Building Regulations, and if it is not done right, the full force of the Building Inspectors may be felt.

When it comes to the Building Regs, we will never compromise and neither will our customers when they understand what’s at stake.

Energy Performance (Doc L) is one of the most well-known of the building regs. It’s expected that windows will comply with the latest requirements, but

I

80 NOVEMBER 2021 PROFESSIONAL BUILDER

it’s important to understand what the requirements for your specific project are, as they do vary and sometimes the specification of the window, in particular the glazing, may need to be altered to ensure compliance. Don’t be fooled by the belief that triple glazing is the solution, sometimes it’s actually less efficient than double.

Vents

Vents are the most contentious of any detail on a window. They are hugely important because they remove stale air and reduce condensation and help to prevent mould. They also allow

ventilation whilst the windows are locked, and security is a key requirement of most homeowners.

But many homeowners object because they spoil the clean lines of their windows and, actually, even the best of them let heat out and noise in.

But here’s the rub: in the next round of Building Regs, inspectors are expected to be even keener when it comes to checking vents are used where they should be. Our advice? Get over it: windows without vents will fail the building inspection.

Security and PAS 24

Alongside aesthetics, security is ranked the most important factor by homeowners choosing new windows and doors. This reference confirms that the hardware performs to the minimum requirements of the Building Regs for that most essential requirement of windows and doors: keeping out the bad people. Use it to your advantage and regale your customers about the

features of and how it enhances the security performance, the rigorous testing it’s passed and so forth. It’s worth having, not just because you have to have it.

Toughened Glass

There is no way we can ‘knock a couple of quid off by putting ordinary glass in everywhere’ (we have been asked!). It is a requirement in the UK to have toughened or tempered safety glass fitted in windows and doors in areas of a home that are clearly defined by the Building Regulations, as a minimum requirement. We believe that safety should never be compromised and no decent fabricator will supply products that do not comply.

Emergency Egress

The provision of ‘Emergency Egress’ through windows in a home is clearly determined in the Building Regulations and has been since 1997. Despite this, it is the area that is often overlooked, not least because non-compliance will not prevent the sale of a house. The Regs say that every habitable room should have a fire escape window, the dimensions for which are clearly defined.

We are happy to advise on this requirement and, whilst we can guess sometimes that the rule is not being applied, such provision is entirely reliant upon the contractor. However, if the fabricator is falsely selling a product e.g.

A rated when in fact it’s B rated, or if the trickle vent doesn’t meet a certain air flow etc., then the fabricator may also face fines.

Such things seldom occur in our experience. But rumour is that as the Regs become stricter, inspectors will be better equipped with tools to ensure compliance. Our advice is to start getting into good habits now and avoid some expensive remakes in the future.

ADE’S TEA-BREAK TEASER A professional builder was walking around on site when it started to rain.

The builder didn’t have an umbrella and wasn’t wearing a hat. His clothes got soaked, yet not a single hair on his head got wet. How could this happen?

resurrected yet again. This time because the Prime Minister has proposed to bring back pounds and ounces, as part of a “bonfire of EU regulations”.

As I might have mentioned in this column before, however, the metric system is not actually a fiendish plot by the European Union, but rather a universal system of measurements used by most of the World, including Commonwealth countries, former Eastern Bloc countries, and most developing nations.

Our use of the metric system dates back over a century and a half, to 1856 when Britain agreed with other countries to adopt the SI single system of measurement, and signed up to the OIML (International Organisation of Legal Metrology). Metric measures first become officially lawful in the UK in 1875.

In any case, as with most things, we British are a versatile lot, and we use whichever system of measurement we find most convenient. We are happy to buy a pint of beer in a pub, or a 500ml bottle of beer from a shop. Cow’s milk is sold in pints, other milks are sold in litres.

We weigh ourselves in stones and pounds at home, or in kilograms at the doctors.

We describe our heights in feet-and-inches, but we also know how tall we are in metres, because that’s how it appears in our passports.

We are happy to buy petrol and diesel by the litre, but discuss our vehicles’ fuel efficiency in miles per gallon.

The British building industry has been metric since 1970, but we still talk about “four-by-two” timbers, and “eight-by-four” sheets of plywood. We all know what we mean.

We use tape measures marked with both types of measurement, and it’s sometimes handier to measure things roughly in inches – such as when cutting lengths of lining paper for cutting-in on the wall.

Well, the numbers on the tape are bigger, aren’t they?

I did once employ a carpenter who insisted on using imperial measurements only. He had a strange hatred of anything that he perceived to be “foreign”. Unfortunately he wasn’t the brightest, and frequently had trouble, mixing up his seven-eighths and his fifteen-sixteenths. After he had sliced too much off the bottom of yet another fire door, I had to let him go.

Millimetres would have made life so much easier for him, and kept him in a job, too.

Fortunately, most of us builders are used to working in both metric and imperial measurements, and we have no particular ideological preference for either.

But I do find it a bit odd that the new “Global Britain” wants to revert to a measuring system used only by the USA and Myanmar.

GOOD HEALTH NO.26 OBSTRUCTIVE SLEEP APNOEA (OSA)

Let’s talk about OBSTRUCTIVE SLEEP APNOEA (OSA)...

Specifically, this article will cover a condition called obstructive sleep apnoea (OSA), which can have a significant impact on overall health. So, firstly, what causes snoring? When we are asleep, the muscles and tissues of the upper airway relax. This relaxation can lead to mild narrowing of the airways and breathing can become noisier as the tissues vibrate with the passing air. Being overweight, consuming alcohol, smoking or sleeping on your back can all make snoring worse.

Most of the time, snoring is not a sign of anything serious although it can cause a lot of problems in a household! Changing sleeping positions, reducing alcohol, weight loss and stopping smoking can help reduce the severity of snoring. Using devices such as mandibular realignment splints can also help by ensuring your jaw is in a forward position and the tissues do not narrow the airway during sleep. Having a clear, uncongested nose can also help reduce snoring, so trials of nasal strips or nasal sprays may also be used.

THIS MONTH GP, ALICE FITZGIBBON DISCUSSES SOMETHING COMMONLY COMPLAINED ABOUT BY PARTNERS AND FAMILIES ALL OVER THE WORLD – SNORING!

the DVLA may need to be informed and you may need to stop driving until the symptoms are controlled.

So how is OSA diagnosed? A lot of the time a patient and their family can give a good history which explains the symptoms. A questionnaire called the Epworth Sleepiness Scale can be completed and the answers give a score which rates the severity of daytime sleepiness. Patients can be referred to specialist sleep clinics for further tests if required. These tests involve wearing monitors overnight that check heart rate and breathing during sleep. The results can identify how severe the OSA is.

Managing obstructive sleep apnoea will depend on the cause. Losing weight if overweight can help. Having surgery to reduce Warning signs enlarged tonsils or adenoids can also help if So, when is snoring a sign of something more these are contributing. Having a healthy serious? Snoring, along with waking up during the lifestyle – reducing alcohol and stopping night gasping for breath and/or having excessive smoking – is recommended.
