On 16 June this year, it will be 10 years since Twinstar Precast opened its doors and began manufacturing custom precast products for the civil engineering and building sectors.
With a casting area of 150m², an office area which had been converted from a horse stable, only one order, a concrete mixer, two wheelbarrows and six staff members, the company took a giant leap of faith in pursuing a passion for precast concrete, specifically custom designs.
Its determination more than paid off, as the next decade of success has shown. Today, the company is acknowledged as a respected and trusted industry leader, with a reputation for expertise and excellence in both its service and products. It now has 1 150m² of casting area, an office adjacent to its factory with interlinking doors between them, four Silla concrete mixers, 18 factory staff members, one office assistant, two managers and its founder and MD Annemerie Coetzee.
Twinstar Precast solves the difficult, onceoff jobs as well as those on complicated sites that can make civil engineering and construction challenging.
Not all building contractors have the necessary expertise, manpower or facilities to manufacture such products on site. For that reason, it is Twinstar’s express aim to assist both civil engineers and civil engineering contractors dealing with difficult worksites and situations in which using currently available precast concrete products will simply not work.
The company has specifically geared itself to undertake these types of once-off jobs, which are typically avoided by many precasters due to their complexity, size and resource-intensive nature. Customised precast products require additional effort and time to design with their once-off moulds. They can also disrupt normal production lines, due to their need for additional skills and supervision.
The company manufactures products ranging in weight from 2kg up to 6 tons. As a result of the complexity of this type of work it remains the only company in the country specialising exclusively in custommade and one-off, unconventional precast concrete products.
Any other sizes can be manufactured on request, as Twinstar specialises in custom sizes and once-off items. Its products are known and respected throughout the construction industry for their durability, versatility, cost-effectiveness and visual appeal. They are manufactured using advanced techniques and undergo stringent quality checks before being made available to clients. The products are supplied with meticulous manufacturer’s guidelines for installation which ensure correct positioning, proper alignment and stability.
The company’s success is the result of its strong relationships within the industry, ranging from civil engineering contractors – its direct customers – to architects and specifying engineers who conceptualise requirements. It enjoys a unique relationship with mainstream precast concrete companies who pass on referrals and use Twinstar to supply certain non-standard products to keep their clients happy.
…TO THE CONVENTIONAL
Twinstar also always keep a few fast-moving products in stock which are standard specifications in tenders and drawings. Companies which previously manufactured them have either stopped or have closed down. This is another reason for Twinstar’s singular positioning in the industry as a manufacturer of products for both conventional and customised requirements of all types.
“Solving a client’s problem is what we do, no matter how big or small,” says Coetzee.
“With theft of all types of equipment rising every day in SA and the current situation, in which law enforcement is failing to curb this, we’ve been approached by numerous clients to come up with a solution to protect equipment with concrete enclosures. In response, we’ve designed and manufactured different types of enclosures to safeguard
various types of equipment, such as electrical components, solar equipment and batteries.
“Some of these enclosures or bunkers have been designed by the clients and brought to us to cast and test their durability. Others have been designed by us, after a client has approached us with a problem and asked us for a solution. Still others have been designed, cast and eventually perfected by us after a client has explained a problem and requested our help. In every case, however, we’ve ensured that we’ve provided the correct product for the job and kept the client happy.”
With this type of service ethic and legacy behind it, Twinstar Precast can celebrate its 10th birthday secure in the knowledge that there will be many more decades of excellence ahead.

South Africa is faced with a severe youth unemployment crisis, disproportionately affecting underskilled workers. A key driver of employment in this space is the construction and infrastructure development sector, which regularly employs lower-skilled, disadvantaged workers from the local communities in which projects are based.
The challenge is clear: joblessness among South Africa’s youth is exceptionally high, having reached 43.8% among 15- to 34-yearolds in the first quarter of 2024, underscoring the urgency of the issue.
It’s concerning that many households, particularly in underdeveloped areas, rely on the income of only one person, especially as this responsibility often falls on a young person. This means that for every young person who’s unable to find a job, there may be a family who cannot afford to buy food that month. This struggle is a reality that many of us growing up in townships and villages have experienced.
Furthermore, these individuals often cannot pay for schooling for themselves, their younger siblings, or their own children. This means that younger generations are being deprived of the necessary education and skills to break the cycle of poverty. Likewise, economic growth and development are stunted, as a large portion of the population remains undereducated and unable to contribute meaningfully to the workforce.
This also has significant consequences for industries that find it increasingly difficult to source skilled workers to fill roles such as plumbers, electricians, carpenters, and surveyors, all of which require a considerable amount of training.
The solution to the sector’s employment challenges is for construction companies to continue hiring from the communities where their projects are based, particularly focussing on young, unemployed residents. But companies must go one step further to provide the necessary training to ensure
Ultimately, by emphasising youth employment and upskilling practices, the construction industry can invest in meaningfully changing the lives of those most in need.
that these individuals have both the skills needed to make the project a success and to access future employment opportunities.
By equipping individuals from disadvantaged backgrounds with the required skills, we can address unemployment and build a talent pipeline that will fuel South Africa’s infrastructure development for years to come.
For example, Gap Infrastructure Corporation’s (GIC) Kathu project in the Northern Cape involved the construction of roads and storm water drainage, and a water and sewer network for around 5,100 homes. From the beginning of the project,
youth workers were employed and upskilled from the local community and became responsible for 72% of work conducted. Our goal was to empower these young workers to go on to establish their own small construction businesses, or to empower them with the skills needed to access future career and employment opportunities.
However, creating jobs and upskilling young and inexperienced employees is just the first step. Lack of education is still a major concern, as last quarter’s employment statistics reveal that only 9.8% of employed youth were graduates.
To truly empower individuals from disadvantaged communities for success in construction, education and skills development are crucial. This is where platforms like Technical and Vocational Education and Training (TVET) colleges, apprenticeships, and science, technology, engineering, and mathematics (STEM) education are particularly important.
We need to see more companies working with the relevant tertiary institutions to help workers obtain relevant qualifications to market themselves for the future. Collaborative efforts with these institutions can also result in the development of specialised training modules that better ensure that graduates are job ready.
Moreover, construction companies can provide students with internship and mentorship opportunities which offer invaluable hands-on experience and exposure to real-world projects. This will allow students the chance to apply their theoretical knowledge in practical settings and provide companies with direct access to well-performing and qualified workers the moment they graduate.
Ultimately, by emphasising youth employment and upskilling practices, the construction industry can invest in meaningfully changing the lives of those most in need, while reducing youth unemployment and helping to build a technically skilled workforce for the industry to draw from in the future.

Through the ages building materials of different sorts have come into and out of fashion as shortcomings or cost prohibitions have shown the materials to be less suitable for modern societies’ needs.
However, concrete has been around for thousands of years and is still by far the most widely used building material due to its strength, endless possibilities of design and relative low cost. In addition, concrete structures have the ability to last several lifetimes and concrete structures built today, may we still be standing in hundreds of years from now.
In practice concrete is the perfect building material. It is cheap and readily available, can be formed into nearly limitless shapes, sets as hard as stone and has the structural strength to support high rise buildings. In large-scale construction projects users even have the ability to order it precast and erected on site, ready-mixed and simply poured in place or mixed insitu.
Throughout the world concrete’s popularity is soaring. In fact, its thermal properties and resistance to damage from seismic or even terrorist attacks has led to somewhat of a resurgence of its popularity in recent years.
Modern concrete is so versatile that is can even compete with other materials with special characteristics. Even though a building’s function and user requirements will always determine which materials are to be used concrete has evolved and can fulfil a surprising number of requirements. For example, some materials allow lightweight construction, while others enable long spans to be incorporated into a structure or provide thin frames to support glass facades.
Concrete by comparison can achieve all of the above to an extent if required. In addition it is thermally dense and is fire and impact resistant. In the construction of any structure, from a house to a railway bridge, tunnel or
In practice concrete is the perfect building material. It is cheap and readily available.
skyscraper it is hard to beat concrete for versatility, strength, availability and price.
Modern concrete gives architect’s room to manoeuvre and approach each design job with a clean slate with very few limitations. Concrete is also stronger and safer in most instances considering that the new World Trade Centre in New York has concrete safety measures including a 60cm concrete wall enclosure for its building core that houses the elevators, stairs and power system for protection from fire or terrorist attack.
Better materials, additives and techniques are enabling us to develop new techniques in all areas of construction, from roads to buildings and infrastructure. We are witness to new developments every day such as our new freeways, rail infrastructure, bridges and
thousands of other successful projects which bear testimony to the availability of highquality cement and concrete right here is South Africa.
Contractors should still be aware of the limitations and always seek the advice of concrete professionals for mixes and laboratories for testing when undertaking new projects. They should also only make use of quality suppliers who are bound to uphold prescribed standards.
In this way users can get the full benefit of concrete safe in the knowledge that the type of concrete they ordered is delivered and will have the right properties that they require. Maybe the only limitation to concrete is that users should be aware of quality issues and only make use of reliable suppliers.
Concrete professionals can improve performance and mitigate risks through customised concrete mixes and rigorous testing processes. Tailored solutions ensure that concrete meets specific project demands while avoiding the expensive overuse of materials and minimising risks associated with structural failure or noncompliance with specifications.
Mix designs customised to a project’s unique specifications also enhance workability and optimise curing times, which can lead to shorter project schedules and reduced labour costs. The right concrete mix not only ensures the longevity of the structure but also helps projects stay on budget and within deadlines. With effective quality control measures in place, potential issues are detected early, minimising the risk of delays, costly repairs or regulatory penalties.
For South African construction professionals these benefits are invaluable. In an industry where efficiency, cost-effectiveness and quality are important, custom concrete solutions are critical to success. David Jones, managing director of concrete specialist company, Concrete Proficiency, explains how his company’s personalised mix designs and comprehensive testing services deliver these essential benefits to clients across the construction sector.
Concrete Proficiency specialises in creating custom concrete mixes that improve overall project performance while delivering substantial cost savings. According to David, one of the biggest advantages of working with professional mix designers is the ability to tailor each concrete formula to the specific requirements of the project. “Customising concrete mixes helps prevent the overuse of expensive materials like cement and admixtures, leading to direct cost savings,” he says.
David adds that Concrete Proficiency’s approach also focuses on ensuring the workability of the concrete—an essential factor in reducing labour and equipment
wear. “We aim to make the concrete easier to work with, which saves both time and labour. “By optimising curing times, we can shorten project timelines, which leads to even further savings.”
These optimised mixes also enhance longterm performance by ensuring that the concrete meets strength and durability requirements. One of the company’s recent projects involved a client working on complex precast elements that required both high strength and self-compacting concrete. The company’s experts developed a mix that met these demands while ensuring smooth application and adherence to the project’s tight strength specifications.
In addition, tailored mixes help eliminate waste by using the exact quantities of materials necessary for optimal results. This material efficiency not only prevents overuse but also ensures that all components contribute effectively to the final product, reducing the likelihood of costly rework or material shortages.
The importance of testing cannot be overstated when it comes to maintaining the quality and performance of concrete. Concrete Proficiency’s extensive testing services provide an additional layer of quality control that ensures its clients’
concrete meets the required specifications throughout the entire project lifecycle.
“We conduct ongoing testing to ensure the concrete performs consistently. This continuous verification helps us identify any deviations from the expected performance early, enabling us to take corrective action before a small issue turns into a costly problem,” he adds.
David explains that Concrete Proficiency offers a wide range of tests tailored to specific project needs, including compressive strength tests, abrasion resistance, water absorption and aggregate analysis. These tests help assess the concrete’s ability to bear loads, resist wear and prevent water penetration, all critical factors in the longevity of a structure.
For projects that require specialised testing beyond its in-house capabilities, the company partners with local laboratories to ensure that all necessary testing is conducted to meet the client’s specifications. This collaboration with local experts ensures that the testing process is as thorough as possible while leveraging regional knowledge for even better results.
In cases where concrete failure occurs, Concrete Proficiency’s test results can provide crucial insights. Individualised test data helps pinpoint the root cause of issues, whether they stem from material defects, mix inconsistencies or environmental factors specific to the project site. This detailed
analysis enables swift implementation of corrective actions, minimising downtime and additional costs while helping prevent future problems.
“Our data-driven approach aids in resolving issues quickly and ensures that the project can continue without unnecessary delays. The key is to identify potential problems as early as possible, allowing the client to make informed decisions and avoid any disruptions to the project schedule.” says David.
It is important to note that by using tailored concrete mixes and performing ongoing testing, construction professionals can significantly reduce the risks associated with poor-quality concrete. Customising concrete properties to meet a project’s exact needs helps mitigate risks related to structural failure, non-compliance with specifications and long-term durability issues.
Tailored mixes are essential to addressing the unique challenges and conditions of each project. This approach ensures that the concrete meets both the engineer’s requirements and the customer’s expectations, minimising the likelihood of failure or costly rework.
By working closely with engineers and contractors to understand their specific needs, Concrete Proficiency ensures that all concrete mixes are designed to perform under the unique pressures of each project. This proactive approach to risk mitigation
helps safeguard the integrity and success of the project, providing peace of mind for all parties involved.
Another key strength of Concrete Proficiency is its ability to leverage local expertise and partnerships. In addition to its own technical capabilities, the company collaborates with local laboratories to provide specialised testing services when needed. This partnership allows the company to offer a comprehensive range of services while ensuring that all tests are tailored to the local environment and conditions.
“It’s about bringing the best of both worlds—our technical expertise and the local knowledge—to deliver top-tier results.”
Concrete Proficiency’s focus on delivering personalised concrete solutions, rigorous testing and local expertise has made it a valuable partner for concrete professionals across South Africa. From precast manufacturers to large construction companies, Concrete Proficiency’s tailored services ensure projects are completed efficiently, on time and within budget.
“The key to our success is an unwavering commitment to quality and client satisfaction. We treat every project as unique and ensure that our clients receive the best possible results. By offering custom solutions and continuously monitoring performance through testing, we also help our clients achieve their project goals without unnecessary risks,” concludes David.
Sustainable construction needs to start at the very foundations of all business projects with the sand and aggregates that constitute the largest part of just about every construction project.
This is an often-overlooked element of sustainable construction and required that all materials used for ground stabilisation and concrete be manufactured with sand and stone that is procured through registered legal entities that adhere to all the relevant legislation relating to the environment.
All too often sand and stone is overlooked by green building practitioners, yet it constitutes the largest component of any construction work. By volume sand and stone makes up by far the biggest percentage of the dry mix of concrete and it is vitally important that a paper-trail be followed to ensure the materials are obtained from legal mining operations.
The Government have thrown their full weight behind programs to help protect the environment upfront and adopt sustainable mining practices in their everyday operations.
Sand and stone suppliers, as well as readymix or prefabricated concrete suppliers should be able to prove the supplying mine is operating with a valid mining licence from the Department of Mineral Resources and Energy (DMRE), has land-use rights from the local, provincial and national authorities, as well as complying with all relevant environmental protection requirements.
It is an unfortunate fact that illegal mining practices continue to scar our landscapes and diminish the lives of surrounding communities and others that are affected by the practice.
Building professionals should also remember that unscrupulously operated pits and quarries scar the environments and contaminate water courses. Damage in these cases is most often left for future generations to clean up. That is why mines and quarries have thrown their full weight behind programs to help protect the environment upfront and adopt sustainable mining practices in their everyday operations.
Increasing environmental awareness needs to ensure compliance with regional and national bylaws and legislation.
Menlyn Taxi Rank is a recently completed, fast-tracked project by Concor to reconfiguration an underground parking area into a taxi holding facility at Menlyn Park Shopping Centre.
Apart from the exceptional workmanship undertaken during the project it was also honoured by the Master Builders Association (MBA) North, for its adherence to tight safety protocols which saw it winning in the regional category for projects under R15 million. The MBA North regional safety competition saw 67 entries, including 60 principal contractors and 7 sub-contractors.
Menlyn Park Shopping Centre, one of South Africa’s largest mega shopping centres, boasts a diverse array of over 500 shops, restaurants and entertainment facilities. The centre attracts a vast number of shoppers and visitors each month, necessitating a significant workforce to support its operations. While some commuters use personal vehicles, the majority rely on minibus taxis for transportation. To streamline this process and enhance the commuter experience, a Public-Private
Partnership was established for the construction of the taxi holding facility.
Concor contract manager, Martin Muller explains that the company is known for managing high-pressure construction programmes effectively, and applied attention to planning underpinned by effective programme management to
ensure every phase of the project dovetailed seamlessly, meeting tight deadlines without compromising quality or safety.
“Our ability to deliver projects on time, within budget and to the highest safety standards was evident throughout this project,” he says. The project, initiated in February 2024 and completed by April 2024, was delivered on time and within budget, ready for the official opening by the Tshwane mayor.”
Despite the tight timeline, the project was executed without any incidents, a testament to the rigorous safety protocols implemented. The construction site, active within a live retail environment, required meticulous traffic management and pedestrian safety measures. A full-time safety officer ensured compliance with all safety procedures, leading to a Five Star safety rating from the Master Builders Association (MBA) North.
Another of Concor’s significant strengths lies in involving local SMMEs and individuals from the communities where it operates. On this project, Concor engaged with community representatives to source, vet and employ SMME subcontractors, offering opportunities in trades such as brickwork, plasterwork, painting, paving and plumbing.
Martin says that while the contract period was too short for a formal skills development programme, local labourers were given the chance to work on the project, gaining valuable experience and mentorship.
The drop-off and pick-up facility is strategically located on the northern side
of the centre, accessible from Atterbury Road. This facility enhances the movement of taxis, allowing for safe drop-off and pickup of passengers. Commuters benefit from a designated pedestrian walkway leading directly into the mall, which is both safer and sheltered from the elements.
The facility can accommodate around 40 taxis at any given time within its spacious footprint. The construction involved
extensive groundwork, soil stabilisation, and paving to ensure durability under high traffic volumes. Security measures include fencing around the area and structural steel canopies with reinforced concrete
foundations. The pedestrian walkways were also designed with aesthetic landscaping.
In addition to the primary logistical infrastructure, provisions were made for registered informal traders to set up kiosks, offering food and other goods in a secure and sanitary environment with shelter from inclimate weather. Nearby, 24/7 accessible ablution facilities ensure safe and hygienic conditions for commuters and taxi operators.
Martin explains that previously, taxis lined Lois Avenue on the eastern side of Menlyn Park Shopping Centre, creating hazardous conditions for both commuters and other vehicles. “The new facility alleviates these issues by providing a controlled environment for taxi operations and commuter safety.”
The project was executed without any incidents, a testament to the rigorous safety protocols implemented.
The taxi holding facility was integrated within the centre’s existing parking structure. It includes 165 parking bays, with 135 for standard minibus taxis and the remainder for larger long-distance minibuses. Access is controlled via license plate recognition, with separate entrances for short-distance and long-distance operators. The area is secured with fencing, and the parking layout was upgraded with energy-efficient LED lighting and clear demarcation of bays.
The holding facility also features utility areas, including a rest area with a kitchen, ablution facilities catering to disabled individuals and a wash bay. With a focus on the environment, sustainable design elements were incorporated such as sensorbased lighting and water-efficient fixtures to reduce resource consumption. The dedicated wash bay encourages water conservation among taxi operators while providing a suitable vehicle cleaning area.
As with all its contracts, Concor’s commitment to community upliftment extended beyond the project site with the company identifying needs within local communities. In this instance the company donated building materials to a nearby school for an upgrade project, collaborating with the professional team to support local education infrastructure.
“Concor’s successful execution of the Menlyn Taxi Integration Project underscores our capability in handling complex projects fast track projects with precision and excellence,” Martin says. “This project not only improved the commuter experience at Menlyn Park Shopping Centre but also, once again, showcased our dedication to quality, safety, and community engagement.”
Concrete Manufactures Association (CMA) member, Terraforce, has scored another notable offshore retaining wall success.
Its Terraforce® L12 rock-face Concrete Retaining Blocks (CRBs) have been used for the construction of segmental retaining walls at La Almudena Cemetery in Madrid, Spain.
Built in 1884, the 120 acre cemetery is Europe’s largest and a popular tourist attraction. With close on five million graves, its monuments display various architectural styles: Neoclassical, Neo-romantic or Neomudejar and typical Madrilenian.
Required to create horizontal platforms and terraced gardens from a plot previously filled with waste material, the retaining walls were designed by ORBE Técnicas Medioambiente and Prensagra Prefabricados manufactured theTerraforce® CRBs.
“Initially the plan had involved the construction of in-situ concrete walls,” said ORBE civil engineer, Miguel Seller. “However, the presence of extremely soft soils up to great depths led the project team to seek alternatives, because in-situ wall foundations would have been prohibitively expensive.
“Geotechnical testing helped us arrive at optimal wall designs and we recommended

the installation of green reinforced soil walls (Green Walls) in certain areas and segmental walls in others.
“At a maximum of three metres, the segmental walls were not particularly high. In the past we have built 10m walls using Terraforce blocks. We analysed internal wall stability using Terraforce’s Maxiwall Pro software, and we compared the results with our own software analysis and a global stability assessment. Based on this research, we proposed reinforcing the foundation beneath the segmented wall with geogrids and improved soil.”
All told 10 500 Terraforce L12 blocks were installed, resulting in visually striking rockface walls. Reinforced with geogrids at every second row and stepped outwards at intervals with precise ninety-degree corners, the walls also accommodate gently sloping access ramps, stairs and rectangular garden features. To finish off the overall linear look, straight-lined steel rails were inserted into top row of CRBs which had been filled with concrete for that purpose.

South Africa’s national standard for the manufacture of Concrete Block Pavers (CBP), SANS 1058:2021, is based on several performance measurements. Tensile-splitting strength, abrasion resistance and water absorption are the three major evaluation criteria but the standard also covers shape, appearance, colour, texture and dimensions. It has been this way since 2012 when tensilesplitting replaced compressive strength in SANS 1058:2010, a new standard which provided a more appropriate means of testing the performance of CBP. The standard has subsequently been updated in 2021.
Notwithstanding that the standard is now in its 12th year, many CBP specifiers, be they engineers, architects or other related professionals, are still specifying compressive strength rather than tensile-splitting strength as the defining performance measurement in tender and design documents. This disturbing revelation was recently brought to light by the Concrete Manufacturers Association (CMA) which says that all its CBP producer members are confronted with misspecified CBP tender and design documents on a regular basis.
CMA general manager, Henry Cockcroft, says that by preparing specifications based
on the old compressive strength standard, mis-specified products are being released onto the market.
“This leads to product failure which in turn results in liability claims and expensive remedial work.
“The old standard was revised because compressive strength only prevents pavers from crumbling under pressure, which is something seldom seen in CBP installations. Rather, cracking under pressure, or point load fractures, is the common cause of paving failure, and it is countered by appropriate levels of tensile-splitting strength,” says Cockcroft.
Despite the disparity between the two performance measurements there is a tenuous relationship between them and this was explained with the release of SANS 1058:2012 which introduced two new tensile-splitting classes, Class 30/2.0 and Class 40/2.6.
Class 30/2.0 calls for a tensile-splitting strength of 2MPa and a note in the specification says this is indicative of a compressive strength design of 30MPa. The second new class is Class 40/2.6 which specifies a tensile-splitting strength of 2.6MPa and is indicative of a compressive strength of 40MPa.
Based on the feedback from CMA CBP producers it would appear that some professionals remain unaware that the compressive strength standard is no longer valid even though it was revised 12 years ago. Others might think that because there is a correlation between tensile-splitting and compressive strength, one can simply specify a compressive strength of say, 30MPa, to achieve the Class 30/2.0 tensile-splitting strength. This is patently not the case.
The operative phrase in the updated standard is ‘indicative of’’ and not ‘equal to’. And even if one could accurately determine the compressive strength of a paving block based on its tensile-splitting strength, which one can’t, the reverse, namely, determining tensile-splitting strength based on a compressive strength, especially if the specifier is unaware of the ingredients in the CBP concrete mix, would be nothing more than a stab in the dark.
This has been clearly outlined in a technical note published recently by the CMA. It
Based on the feedback from CMA CBP producers it would appear that some professionals remain unaware that the compressive strength standard is no longer valid even though it was revised 12 years ago.
cites how tensile splitting strength won’t necessarily increase when compressive strength is improved.
For instance, it states that if the sand content in a concrete mix is increased it results in higher compressive strengths, due to higher density. But increasing sand content reduces sheer or tensilesplitting strength. This can mainly be attributed to the homogeneous shape of sand particles and the way they bind with cement. Conversely, if the sand content is reduced and stone content increased, tensile splitting-strength will improve. This is because the random particle shape of stone contributes to a less favourable sheer path, thereby realising a higher tensile-splitting strength.
“Therefore to avoid any confusion is vital that specifiers use SANS 1058:2021 in their design and tender documents. It is written in such way that if specifiers adhere to its two performance classes which cover tensile-splitting strength, abrasion resistance and water absorption, there is not much that can go wrong with a CBP installation providing it is laid according to the correct installation specifications. And even if specifiers do not refer to the standard,
they should at least use tensile-splitting rather than compressive strength as their performance measurement.
“It’s hardly surprising that CBP remains the world’s most versatile method of pavement construction: it is labour intensive and creates job opportunities; its weathering is totally different to any other type of paving material; and its durability properties are much higher than most other types of paving materials,” concludes Cockcroft.
CMACS, the Concrete Manufacturing Association’s certification arm, has gained a second Namibian client, Vula Namibia. The company’s first audit took place in May which it passed with consummate ease.
Founded in 2016, Vula started by importing infrastructure products from South Africa. However, when the price of diesel spiked in 2019 this business avenue was no longer competitive and a decision was taken to begin local manufacturing. To this end a new plant was established 15km outside Windhoek in 2020 and it now supplies infrastructure products throughout Namibia, parts of Botswana and the Northern Cape.
Vula’s product range comprises stormwater pipes, culverts with base slabs, precast concrete toilets manhole chambers and cover slabs, kerbs, and other precast concrete products.
Vula sales manager, Brendan Britten, says that from the outset the company has been producing stormwater pipes, culverts, manholes and covers to SANS standards and certification.
“We would not be able to sell these products unless they were SANS certified and this meant that well before our first CMACS audit, we already had a good quality management system in place to obtain SABS certification. What we liked about our CMACS audit was that it was done on time and only took two days. This is crucial because any delays in the

certification process is costly, holding up sales and distribution.
“All our certified products are manufactured to a minimum of 40MPa and our batching is done via a combination of electronic and manual controls. And like all well-run precast concrete plants our quality management process begins with raw material testing.
“We do a sieve analysis of our aggregate and sand deliveries, checking for stone size and sand impurities, and our cement suppliers provide us with test certificates. The testing of our finished product
range involves submersing sample cubes in temperature-controlled water and thereafter we subject them to seven-day and 28-day compression tests. We also do density testing for products destined for coastal areas.
“We were very fortunate in that when we opened our factory we received a substantial order to supply civil products for the construction of a highway to Windhoek’s new international airport. The market is somewhat quiet this year with everyone waiting for some large budgets to be released,” concluded Britten.

The site on which the Brodie Room stands is exceptional in that it is the only portion of the school grounds which is not owned by the government, but rather by the Old Boys Union. This was the result of a swap that occurred when the school relocated from the city to Newlands in 1960. The Old Boys Union owned the land on which the Memorial Fields now stand and they agreed exchange them for the site where The Brodie Room was subsequently built.
Old boys and parents donated generously to the building fund. However, the building was named after Bernard Brodie who attended the school from 1927 to 1936, and who was the major contributor to its construction.
Founded in 1829, SACS is arguably South Africa’s oldest school. And many old boys are illustrious public figures such as, to name a few: Dr Abdullah Abduraham; Jan Hofmeyer; Peter Kirsten; Percy Montgomery; Dr Cecil Moss; and Albie Sachs.
In 2022, The Brodie Room, a building which overlooks the two Memorial rugby fields at Cape Town’s SACS high school, underwent a major face lift. What had been an ordinary red face-brick structure built in the mid1980s with a red-tiled roof, was transformed into a building which mirrors the streetfacing facades of two of the school’s administration buildings.
These are graceful structures situated at right angles to The Brodie Room. Embellished with classical Greco-Romanstyled columns and porticos, their walls are clad in sandstone at ground level and plastered above.
The Brodie Room is home to the SACS Old Boys Union and when the makeover was under consideration it was felt that that the building should mirror the sandstone and plastered facades of the administration buildings.
The material chosen to match the sandstone was Ridgestone cast-stone cladding manufactured exclusively by Concrete Manufacturers Association (CMA) member, Revelstone. Applied in three colours,
Embellished with classical GrecoRoman- styled columns and porticos, their walls are clad in sandstone at ground level and plastered above.
Ridgestone is not only indistinguishable from natural stone but is also more affordable. As with the two administration buildings, the lower half of The Brodie Room wall was clad in Ridgestone and the upper section plastered. And a Romanstyled arch, which frames a double-door at ground-level of the building, was also clad with Ridgestone.
The back of the building, which fronts onto a swimming pool, was plastered, and, in keeping with the administration buildings, the roof was painted grey.
Now in its 52nd year the Concrete Manufacturers Association (CMA) is in a good place. Despite being entirely selffunded, the association continues to grow, belying the constrained environment in which it operates; so much so that membership, which now includes 40 precast concrete producers, is at an all-time high.
“The withdrawal of cement industry support, a stuttering economy, and of course the Covid pandemic, has meant we have had to adapt our modus operandi to survive. Not only have we survived, but the steps we have taken means that membership continues to grow,” says CMA general manager, Henry Cockcroft,
“It’s very encouraging to see the CMA brand on an upward trajectory. It is reminiscent of the days when cement producer sponsorship meant that funds were freely available, but today’s membership growth is not inflated because of abundant funding, but is purely organic and sustainably based.
“A major contributing factor has been our Certification Services (CMA CS) arm. Besides providing a SANS certification and auditing service to precast concrete producers it has enabled us to kick start other revenue streams such as consulting on and assisting with the implementation of quality management systems.
“Another significant contributor has been our adoption of social media platforms; they have massively enhanced our ability to ‘talk’ to precast concrete specifiers and to enlighten a large pool of potential precast concrete users as to its advantages.
“It has also given our Awards for Excellence competition a far greater reach and relevance than it had during the from printmedia era. Moreover, we no longer spend a small fortune on black-tie gala events to announce the winners; rather, by using social media platforms, our focus is the creation of ongoing awareness of all award entries from the day we receive them until well after the results are announced.
“And another big plus is that social media publicity is measurable. It enables us to define demographic environment with accuracy, pinpoint our focus market and measure our hit rate in delivering content that draws attention to precast concrete and its numerous benefits. We see this clearly through the calls we receive daily, from consulting engineers, architects and

other professionals. Besides advising them on the technical properties and application of precast concrete products, it gives us the opportunity of promoting our members products, and bringing some of the precast concrete advantages they may not have known to their attention.
“The promotion of precast concrete always has been and continues to be the primary focus of the CMA. The industry has made enormous strides since the end of 2nd World War, extending far beyond the manufacture of bricks and blocks. The CMA logo stands for quality, honesty, professionalism and proper coding conduct, and member companies are obliged to subscribe to these values. However, membership is not open to all comers. Besides the criteria listed above prospective members companies must operate to recognised quality management systems.
“Our strongest membership base is in Gauteng, followed by the Western Cape and then the Eastern Cape and we have members as far afield as Namibia. This year’s AGM was held in Pretoria where the attendance was of over 50% of our membership base, our highest attendance ever,” concluded Cockcroft.
Civil engineering companies need to more consultative style of collaboration approach to address persistent time and quality issues within the construction industry with particular attention to the supply of materials.
Industry experts emphasize the need for a shift from a master-servant dynamic to a model where engineers, contractors and suppliers function as an integrated team. Early and continuous collaboration among all stakeholders is crucial. Each party plays a vital role in the project lifecycle and utilising their expertise from the outset ensures better planning and execution. Engineers, contractors and suppliers should be involved from the design phase through to the final construction phase.
Adopting a consultative approach facilitates the implementation of lean
const-ruction techniques, where the design team and contractor collaborate from the beginning. This approach allows for the early procurement of materials and better preparation by suppliers. Readymix concrete manufacturers, often engaged only after a project is underway, can be better integrated into the planning stages, preventing supply, access and quality issues from arising unexpectedly.
There are challenges in adopting new construction methods, including the need for improved professional services, quality management, strategic planning and thorough documentation. For new techniques to be embraced, it is critical to
compile detailed production information at every stage. This documentation supports quality management systems and aligns the completion strategies of all parties involved.
It is also important to note that selfregulation is crucial and industry standards provide a framework for best practices. Organisations can adopt their own quality management system (QMS) that will play a vital role in helping members adopt higher standards. These standards ensure more reliable and quality-focused contributions to construction projects.
Better-regulated services from suppliers, contractors and engineering teams lead to more efficient planning and higher-quality, timely construction. Adopting a collaborative and consultative approach is essential for the future success of construction projects, ensuring that all parties work together harmoniously from the project’s inception to its completion.
Industry experts emphasize the need for a shift from a master-servant dynamic to a model where engineers, contractors and suppliers function as an integrated team.
Users of readymix concrete don’t always realize that unless otherwise specified, readymix suppliers only test process control tests for their own purposes and users should always specify further tests if that is required for their own purposes.
Professionals know that there is a vast difference between process control testing and testing to meet specifications on site. As a norm readymixers take samples at the plant and not necessary at the point of discharge and only one out of every one hundred cubes are tested.
However, SANS specifications says that for testing concrete to SANS specifications, sampling fresh concrete should be carried out in the middle of a pour per mixer. This must be specified by the user though and if specified must be sampled from the middle 70% of the truck.
If the user does not specify SANS quality readymix then there is no real measure of the concrete being delivered. If nothing is specified then it also does not have to be done, that is why it is important to specify the concrete properties, as well as testing and sampling methods to be used.
In the event of a failure, it has got to be established where the failure occurred, either material, test or specification failure.
everything needs to be done according to the agreed specification. This highlights the importance of all parties agreeing upfront to a testing regimen that is acceptable to all the parties involved in a construction project and that is in accordance with SANS specifications.
Remember, the specification must be measurable for any finding to be made if a claim were to arise.
For example, investigators will ask what was specified and how was this specification contravened? It has got to be fit for purpose so even if it is 30Mpa in terms of strength specification but is not workable or pourable (as required on site) and this was not specified, then the specification failed, not the concrete.
The following five critical points need to be considered for the correct testing to be undertaken:
1. What is specified?
2. What are the acceptance criteria?
3. Who is going to do the testing?
4. Find agreement of testing methods etc before the project starts.
5. Plan to test, you must plan how, where and when testing takes place.
What is important to know is that a test has many facets and for the test to be accepted every one of these must be done according to SANS criteria. If any one of these is not done then one cannot determine the influence of any small inconsistency, so the outcome of the whole test cannot be used.
Nor can it be proved what the result of a small inconsistence will have on the end result of the test. Therefore, everything needs to be done according to the agreed specification. This highlights the importance of all parties agreeing upfront to a testing regimen that is acceptable to all the parties involved in a construction project and that is in accordance with SANS specifications.”
Telehandlers have become indispensable in the concrete industry, offering versatility, efficiency, and increased safety on construction sites. Their unique design, featuring an extendable boom and the ability to lift and move heavy materials to various heights and across challenging gaps, makes them ideal for tasks that require precise handling of concrete products and materials. Construction companies across the world, including South Africa, have integrated telehandlers into their fleets, recognizing their importance in handling materials such as gunite, precast concrete, pipes, hollowcore slabs, lintels, and in-situ concrete.
Telehandlers, also known as telescopic handlers, combine the features of a forklift, crane, and boom lift, providing construction companies with a flexible solution for material handling. Equipped with a telescoping boom, they can lift and place heavy materials at different heights and distances. South African construction firms such as WBHO and Concor, as well as international manufacturers like CAT, Gehl, and Manitou, highlight telehandlers as essential equipment for modern construction projects.
One of the significant uses of telehandlers in the concrete industry is for placing gunite (or shotcrete), a method of applying concrete pneumatically. The extendable boom of a telehandler allows operators to position the gunite nozzle at precise angles and heights, facilitating the even application of concrete on surfaces such as walls, foundations, and tunnels. This is particularly important in
projects requiring intricate detailing, such as swimming pools, retaining walls, and underground structures.
Telehandlers also simplify the handling of precast concrete elements. Precast concrete is manufactured off-site and delivered to construction locations for installation. Telehandlers can be fitted with specialized attachments to lift and transport these heavy panels, slabs, and beams, placing them accurately into position. With their superior reach and manoeuvrability, telehandlers allow construction teams to place precast elements even in confined or hard-to-access areas, increasing project efficiency.
In construction projects requiring the installation of large concrete pipes, hollowcore slabs, and lintels, telehandlers play a crucial role. These materials are often too heavy or awkward to be moved manually or by smaller equipment. With lifting capacities exceeding 5,000 kg in some models, such as those offered by CAT and Manitou, telehandlers easily handle these loads.
For example, when installing hollow-core slabs, which are commonly used in the construction of multi-story buildings and parking decks, a telehandler with an extendable boom can lift the slab from a flatbed truck and position it at the necessary height with precision. Similarly, telehandlers can assist in placing lintels and beams that support structural loads above doorways and windows, improving construction speed and safety.
Telehandlers are equally valuable in in-situ (cast-in-place) concrete projects. In-situ concrete requires careful placement into formwork, and the extendable boom on a telehandler can help deliver concrete to hard-to-reach areas. This reduces the need for additional equipment like cranes or mobile pumps, saving time and lowering costs. Telehandlers also offer the advantage of being able to place concrete directly from the mixer into the form, minimizing the need for manual labour.
The extendable boom on a telehandler offers significant advantages for the concrete industry. Unlike traditional forklifts or other material-handling machines, telehandlers can reach heights of up to 18 meters (in models like those from Gehl), making them ideal for projects involving tall structures. Their ability to extend horizontally also allows for work to be done across gaps, such as placing materials on the opposite side of an excavation or through narrow openings. This flexibility is particularly important when working in tight or complex job sites, where traditional cranes or forklifts may not be able to manoeuvre. The compact nature of telehandlers means they can operate in restricted areas, allowing construction teams to overcome obstacles without sacrificing productivity.
For building contractors, telehandlers represent a significant return on investment. Their versatility means they can perform a wide range of tasks, reducing the need for multiple machines on-site. With the ability to change attachments, such as buckets, pallet forks, and lifting hooks, telehandlers can adapt to the varying demands of concrete handling and installation. This adaptability not only improves operational efficiency but also reduces the cost associated with hiring or maintaining separate pieces of equipment.
Manufacturers such as CAT, Manitou and Gehl offer telehandlers with robust designs, high lifting capacities, and enhanced safety features. For contractors working in challenging environments, these machines provide the durability and performance needed to meet the demands of modern construction projects. Additionally, many telehandler models come equipped with advanced safety technologies, including load management systems and operator-friendly controls, further enhancing their appeal.
Concrete is one of the most versatile and durable building materials available, making it ideal for a variety of DIY projects. From laying garden paths and paving to crafting ornamental garden pieces, mixing concrete at home offers endless possibilities for creative and functional outdoor enhancements.
Whether you’re constructing a small slab or molding decorative features, understanding how to properly mix and use concrete is essential for achieving professional-looking results.
To mix concrete at home, you’ll need the following basic materials and tools:
• Cement: The binding agent in concrete.
• Sand: Provides bulk and texture.
• Gravel or Stone: Adds strength and durability.
• Water: Activates the cement to create a paste that binds the materials together.
• Optional Additives: Such as plasticizers or colorants to improve workability or aesthetic appeal.
• Mixing Tools: A wheelbarrow and shovel for small batches, or a concrete mixer for larger jobs.
A general-purpose concrete mix for DIY projects typically follows a 1:2:4 ratio (cement: sand: gravel). It’s essential to measure accurately and mix thoroughly for a uniform consistency.
Prepare the Work Area: Before you start mixing, ensure that your work area is ready. If you’re pouring concrete for paths, paving, or slabs, make sure your forms (molds) are in place. These forms will shape the concrete as it cures. Clean and level the area where the concrete will be placed.
Combine Dry Materials: Add the dry materials (cement, sand, and gravel) to the mixing tool of your choice. If you’re using a wheelbarrow, shovel the materials into a pile and stir them together. In a mixer, add the dry ingredients and turn the drum on.
Gradually Add Water: Slowly add water to the dry mixture while stirring. Be cautious not to add too much water at once, as this can weaken the mix. The concrete should have a thick, paste-like consistency that holds its shape when formed, without being too runny.
Check Consistency: Aim for a workable consistency that isn’t too dry or soupy. A good way to test is by using a shovel to scoop a bit of the mixture; it should hold together without crumbling but shouldn’t be overly fluid.
Use the Concrete Immediately: Concrete begins to set within a short time, so you should work quickly. Pour it into the prepared form, level it with a trowel or screed, and smooth the surface. For larger areas, you may want to create control joints using a groover to prevent cracking as the concrete cures.
Concrete paths and paving provide durable and aesthetically pleasing walkways for

gardens or outdoor spaces. After mixing the concrete, pour it into pre-prepared forms and spread it evenly. You can add texture by using stamps or brooms, creating anti-slip surfaces and decorative patterns. Adding expansion joints in larger paths will reduce cracking over time.
Concrete slabs are essential for building patios, shed bases, or driveways. For structural stability, a thicker mix with a higher gravel content works best. The concrete should be at least 10 cm (4 inches) thick to withstand heavy loads. Leveling and smoothing the slab while the concrete is wet ensures a flat surface. Consider reinforcing with steel mesh for added durability.
3. Decorative Concrete Projects
For creative DIY enthusiasts, concrete can be used to enhance outdoor aesthetics. By adding pigments or colorants, you can produce colored concrete to match the décor of your garden or patio. Stamping or stenciling patterns into wet concrete can mimic the appearance of natural stone, brick, or tiles at a fraction of the cost. Textured finishes not only add visual appeal but also provide practical non-slip surfaces.
4. Molding Garden Ornaments
Concrete is perfect for crafting garden ornaments, such as birdbaths, statues, stepping stones, and planters. To mold these items, use silicone, wood, or plastic molds designed for concrete. Once mixed, the concrete can be poured into the mold, smoothed, and left to cure. For unique finishes, experiment with adding aggregates like pebbles or glass to the mix, or using textured molds.
5. Repair and Maintenance
Concrete is also great for small repair jobs around the home, such as patching cracks in driveways, fixing broken patio slabs, or
securing fence posts. The same basic mix can be used, and with proper curing, repairs can last for years.
Additives for Improved Performance: You can use additives like plasticizers to make the concrete easier to work with or fibers to enhance its tensile strength.
Curing Time: Concrete should be left to cure for at least 24 hours before walking on it, and a full week before subjecting it to heavy loads. Keep the surface damp during the curing process to prevent it from drying out too quickly, which can cause cracking.
Safety Gear: Always wear protective gear such as gloves, goggles, and a mask when mixing and handling concrete. Cement can be harsh on the skin and the dust is hazardous when inhaled.
Mixing concrete at home opens up a world of possibilities for DIY enthusiasts. It allows for customization of outdoor spaces, whether through practical features like paths and slabs, or decorative projects like garden ornaments. The material is strong, durable, and cost-effective, making it ideal for a variety of tasks. By following proper mixing techniques and applying creativity, homeowners can achieve professional results at a fraction of the cost of hiring contractors.

• Hilti South Africa: Hilti’s South African division provides high-end, professionalgrade concrete saws, along with a variety of diamond blades and accessories, making it a go-to for contractors seeking top-tier equipment.
For building contractors, owning a concrete saw is an investment in precision, productivity, and safety. The ability to make
clean, accurate cuts in concrete and masonry not only ensures the structural integrity of the work but also speeds up project timelines by reducing the need for manual labour.
In addition to saving time, using the right concrete saw minimizes waste by allowing for more accurate cutting, reducing the need for corrections or rework. The safety benefits are also significant, as modern saws are equipped with dust control systems and vibration-reduction features, which protect workers from health hazards associated with prolonged exposure to dust and excessive vibrations.
Furthermore, owning a concrete saw gives contractors greater control over their project schedules, as they are not reliant on renting equipment. This can lead to significant cost savings in the long run, particularly for companies that regularly undertake largescale construction projects.
Ford South Africa has introduced the new transit custom commercial vehicle range with the launch of the base long wheelbase van initially, with additional derivatives to follow later this year.
The next generation of five-time winner of the International Van of the Year is designed to help businesses such as building contractors and construction material suppliers to reduce cost of ownership, work more effectively and achieve new levels of productivity. Ford engineers developed a new platform designed to optimise load carrying and access, improve driver comfort and convenience and deliver outstanding performance and handling, while delivering uncompromised cargo space.
“The Transit Custom is designed and developed in Europe, where it is the topselling van and was the best-selling vehicle overall in the UK in 2021 and 2022, so it has a proven pedigree of being trusted by business owners to enhance their productivity,” says Doreen Mashinini, general manager for marketing at Ford South Africa.
“Ford pulled out all the stops to deliver another huge leap forward for our customers,” Mashinini says. “The new generation Transit Custom’s ground-up customer-led design will set a new benchmark for what small and medium businesses can expect from a commercial vehicle.”
Before Ford designers began sketching the new Transit Custom, the company’s D-Ford in-house human-centred design lab spent
Ford pulled out all the stops to deliver another huge leap forward for our customers,
years engaging with business customers to research their needs and pain points and identify innovative solutions to help improve productivity.
Underpinning the Transit Custom is a new platform designed around optimum load carrying, access, performance and powertrain flexibility. The clean-sheet design is stiffer and 100 kg lighter than that of the previousgeneration vehicle and features a lengthened wheelbase for optimum cargo capacity.
To maximise fuel efficiency, the new model’s body design was developed using extensive aerodynamic simulation. Together with a reduced frontal area, this has resulted in a 13 percent lower coefficient of aerodynamic drag (CdA) compared to the previous-generation model. The vehicle architecture was optimised to help achieve an overall height of under two metres, to improve access in height-restricted areas such as multi-storey car parks, garages and underground loading bays.
A larger side load door aperture enhances loading and the side door features a new integrated access step to make entering the load compartment even easier. Optimised packaging of the chassis and body structure enable the vehicle’s load floor to be lower than that of the outgoing model to facilitate
loading cargo and cab access.
As a large-capacity panel van, Transit Custom offers a total load volume of 5.8m3 with the standard roof height, along with a payload up to 1269kg and a maximum load length of 3050mm using the load-through feature.
Practical features are found throughout the load compartment, including eight load area tie-down loops, partial rubber floor covering, twin 180-degree opening rear barn doors and ultra-bright LED interior lighting. Buyers can select a range of optional features to suit their requirements, including dual sliding side doors, a close assist function for the side doors, a full-width metal bulkhead with a window, as well as a load area protection kit with full height walls and a moulded floor.

Many contractors and suppliers will fondly remember the fabulous ISUZU KB bakkies of old. For years they dominated the sales charts and were regarded as the toughest choice for anybody needing to carry heavy loads like cement, sand and stone. Now, they will be happy to know that Isuzu South Africa has restored one of these gems to better than new condition.
The restoration of a beloved vintage vehicle is always an act of devotion. This is especially
true for the recent revival of ISUZU’s iconic 45-year-old KB bakkie, a rugged, dependable workhorse that has stood the test of time. With its unmistakable charm and storied history, the KB bakkie holds a special place in automotive culture, and its restoration is nothing short of a labour of love.
In early April 2024, ISUZU embarked on an ambitious journey to bring this legendary bakkie back to life, completing the project just in time for its big debut
in June 2024. The KB bakkie restoration was a collaborative effort from start to finish. ISUZU’s Vehicle Engineering team played a central role, with each member contributing their expertise to ensure the project stayed on course. From tackling the day-to-day tasks to allowing key resources to focus on the refurbishment, the entire team rallied behind this passion project.
The bakkie, although drivable when the restoration process began, wasn’t
without its issues. Its chassis and underbody were heavily rusted, and the interior showed signs of decades of use. One of the key challenges during the restoration was sourcing original parts. After all, a 45-yearold vehicle presents a unique problem— many of its original components are no longer in production. Despite these hurdles, the team managed to track down parts from collectors and automotive restorers. At times, modern equivalents had to be sourced from local automotive retailers. One of the most difficult components to replace was the cracked front windshield, which required extensive negotiation but ultimately fit perfectly.
This balancing act—using a mix of original parts and modern solutions—gave the KB bakkie a new lease on life while still respecting its legacy. The team took pride in retaining as much authenticity as possible,
from chrome mirrors sourced locally to vintage wheel caps from a collector. These thoughtful details ensured the bakkie retained its period-correct look, all while overcoming the challenges of sourcing.
The restoration process wasn’t without its share of challenges. “Parts, parts, parts, and time,” was the recurring theme. As a solution, the team employed innovative restoration techniques, combining modern-day technology with respect for the bakkie’s original build. One standout process was the sandblasting and e-coating of the chassis at Kempston Road—an advanced treatment the KB would never have received 45 years ago. While the painting wasn’t intended to be showroom quality, it was deliberately chosen to maintain the rugged, seasoned character of the bakkie—a practical finish that celebrates its long history of service.
In terms of interior restoration, the team aimed to preserve as much of the original look and feel as possible. Time constraints and the project’s overarching philosophy of “doing more with less” meant minimal enhancements for modern comfort. The badly cracked instrument panel was repaired, the door trim panels and seats were cleaned and polished, and an unmoulded vinyl floor mat was temporarily fitted. Despite the minimal upgrades, there’s something incredibly nostalgic about the interior—the kind that takes you back in time to when the KB was a new, shiny vehicle on the market. Plans to source a proper, moulded vinyl mat are in the works, a testament to the team’s desire to perfect every detail.
When it came to painting and finishing the bakkie, the goal was to respect the classic blue shade from the vehicle’s original era to pay homage to the bakkie’s legacy while keeping its spirit alive. The body builders handled the painting process with precision, ensuring that the bakkie would stand out on the road without losing its rugged appeal.
This restoration journey wasn’t about creating a perfect, pristine vehicle—it was about preserving its history and the stories that have been woven into its fabric over the last four decades. Each dent, each worn-out seat, and each faded panel tells a tale of resilience, hard work, and the countless roads travelled. By honouring these imperfections, the team ensured that the bakkie remains a living, breathing artefact of the past, carrying with it the essence of its era while ready to make new memories.
Today the bakkie, once showing its age with rust and wear, now stands proudly as a testament to ISUZU’s legacy of durability, craftsmanship and the ability to thrive under pressure.
As much as ISUZU bakkies are a tribute to the past, they are also designed with the future in mind. Built on a foundation of durability, reliability, and innovation, ISUZU has consistently evolved to meet the demands of modern drivers. Today’s bakkies are equipped with cutting-edge technology, enhanced safety features, and improved fuel efficiency, making them not only tough workhorses but also forward-thinking vehicles suited for both rugged terrains and urban landscapes. With sustainability and performance at the core of their engineering, ISUZU bakkies continue to push the boundaries of what’s possible, proving that they aren’t just built to last— they’re built for the future.
Fleet owners of trucks used in the transport of cement bags or concrete products have an option to rent fully electric trucks from Volvo Trucks South Africa.
The company has announced the introduction of a new Equipment-as-aService (EaaS) model for electric truck rentals in the country. “We recognise that the high initial capital cost of electric vehicles makes them harder for customers to bring into their business, especially those that have shorterterm contracts with their customers,” said
Eric Parry, senior manager of Sustainable Solutions at Volvo Trucks South Africa. “The intention is to bring down the “barrier to entry” for those with the environmental ambition to move to cleaner transport solutions. That is why we will also be offering these as rental units to our customers.”
The local Volvo electric truck range currently consists of FH, FM and FMX models, configured as 4X2, 6X2 and 6X4 Tractors. The company will also soon have FM 4X2 and 6X2 rigids available.
According to Paul Uys, managing director of Volvo Financial Services Southern Africa, “There is a clear demand for rental trucks in South Africa, as proven by the success of companies with their diesel vehicle offer. We will be the first in South Africa to offer EaaS rental solution.”
“The biggest advantage of vehicle rental is there is reduced capital outlay compared to when you purchase a truck. The rental option also allows you more flexibility in using the vehicle for a shorter period,

offer rental customers the necessary charger infrastructure across South Africa, addressing the need for an easily accessible charging network.
“We run detailed simulations for each route that a fleet would like to operate an electric truck in, and this allows us to determine the optimal location and size of the charger. Our trucks can take up to a 250kW DC Fast charger,” explained Eric. “Then, depending on the client’s needs, we will be able to do a site survey and recommend the optimal charger installation for their location. Our supplier will be able to rent the charger to the client for the period of the vehicle rental.”
The Volvo Financial Services EaaS rental solution is based on a period of six months or longer, and the amount will include the maintenance and insurance cost of the unit.
Each truck will be covered by a full Volvo Trucks Gold Maintenance contract for the life of the vehicle.
Special driver training is also available and is aimed at getting the best out of an electrically powered truck. However, the control, couplings and driving style are identical to a diesel model, so there is not much functional training needed.
“A customised and detailed agreement is entered into with each client and is dependent on the vehicle and the type of operations in which the truck will be used,” explained Uys. “The rental units will also incorporate Volvo Connect, allowing customers access to a range of fleet management solutions like vehicle tracking.”
Paul said that at this stage, a ‘rent-to-own’ option is not available but that customers can finance electric trucks with ultimate ownership then subsequently passing to them.

without the commitment attached to a long lease obligation,” explained Paul.
Volvo Trucks’ EaaS rentals will be available countrywide. The company also partnered with an established service provider to
Volvo Trucks currently has three dealers in the major metros, with trained technicians and the specialised tools to be able to support the full electric range. In general, the trucks will only need to come in once a year for service, irrespective of the mileage they travel.
“These fleets are usually running regional operations. From big blue chip corporates to smaller fleets, we have received interest from a range of companies,” said Eric. “The rental option enables them to test out the product in their operation for a meaningful amount of time, without the initial capital investment.”
