WHEN NOT JUST ANY PAVER WILL DO!
Cape-based manufacturer shows the way for quality and price
Trailblazing cement product producer Blublok is redefining value in the construction sector in the Western Cape with its range of impressively high-quality bricks, blocks, kerbs and pavers that are being made available at value prices.
Ther company has concentrated on modernising existing equipment and procuring precision automated plants to streamline its operations and produce quality focussed products at highly competitive pricing.
Under the leadership of managing director Jess Brews (33), leading an energetic young team, the company has set out to be different and find new ways of competing in a highly competitive market. “The market is already saturated, it’s not easy to remain competitive with raw material, cement and diesel prices constantly increasing. Not to mention more and more manufacturers incorporating larger volumes of recycled material into their production at a fraction of
the cost. We pride ourselves in the quality of our products and have embarked on a strategy that focuses on technology and efficient production to maintain this quality while remaining competitive.” says Jess.
Blublok started with an old 1975 German-made Schlosser plant that was recommissioned after being stripped and vandalised over a period of time before the current shareholders bought the site in 2010.
“On further investigation we began to find some key individuals who were involved in the original commissioning of the plant many years earlier. We decided to tenant out the majority of the site, invest in the recommissioning of the plant and manufacture the bricks we needed to pave and complete the building work required on the 40 000m2 site. The bones were there and we needed bricks”, says Jess.
The original plant was, for the most part, completely rebuilt and is still today one of Blublok’s fully automated plants. Over the years, the machine has undergone extensive upgrades and modifications and now predominantly produces Blublok’s bricks and blocks.
The next plant brought online was a sophisticated wet-cast plant focusing on the production of high-quality concrete units, mainly kerbs for the civils market. By 2015 Blublok was supplying their wet cast products to the construction and civils markets alongside their bricks and blocks.
“Wet cast production is labour intensive and slow compared to other types of manufacture, so we have tried to incorporate as much available automation and technology to reduce the factors which traditionally make wet cast operations inefficient. The sophistication of our plant and batching components allows us to maintain a uniform and consistent mix ensuring our quality is maintained and that rejects are limited.”
In 2023, after substantial re-investment from the shareholders, Blublok decided to establish another plant, focussing on the manufacture of paving products to complement Blublok’s existing product offering. After researching the machinery available locally and overseas, Jess settled on another German-made plant which landed in December 2023 and was commissioned by March 2024.
“I am very lucky to have the team I have. We did all the civils works, installed and commissioned the plant ourselves. The new plant has all the bells and whistles and makes what I believe to be the best quality paver from a structural and aesthetic point of view, in the Western Cape.” Says Jess.
“For us quality is not negotiable, and the
Blublok’s factory is well situated to serve the Western Cape market
process begins with procurement of aggregates and cement with carefully created mix designs, machine settings constant production monitoring. We also constantly refine these processes to ensure the reliability and performance of our units, both in the field and according to specifications of our clients. We don’t cut corners,” says Jess. “People are building homes, schools, roads and walls with our products. That means we have a duty to make them right every time.”
This type of thinking is what underscores the company’s rapid rise which is powered by a diverse and motivated team. Jess is quick to credit his colleagues for the company’s success including team members who have business experience outside the manufacturing industry combined with individuals who have decades of experience in the industry. “We are still young and have no plans of slowing down. We have the infrastructure in place to continue to grow and expand our product range. That being said, we work for our share of the market.
This job is hard and requires massive capital, commitment and efficiency to produce enough volumes to survive. When I’m not in the factory, I’m on the phone fighting for prices!” says Jess.
On the distribution side, BluBlok distributes directly from its factory and predominantly uses its own fleet to deliver products and collect raw materials. This gives Blublok the ability to attend to customers as quickly as possible. Blublok products are available to see and feel at the sales office and they are in the process of establishing a “show garden” on a beautiful farm nearby the factory for architects and customers alike to come and see their products in an environment more similar to where they will ultimately end up. This direct-to-customer approach allows clients to see, touch and compare the products before making a purchase. It
also helps the team better understand market demand and customer preferences.
The company serves a diverse market mix from infrastructure developers and largescale contractors, to retailers, homeowners and developers where different products appeal to different projects like landscaping and luxury homes, as well as civil contractors and affordable housing developers.
BluBlok’s reputation is already well established in the Cape Town region and is steadily growing across the greater Western Cape. Customers return not just for the quality but for the reliability of service. “We make it easy to do business with us,” Jess says. “We quote fast, we deliver on time and if there’s a problem, we fix it.”

SEATON INTERCHANGE BREAKS GROUND
The recent groundbreaking ceremony for key stakeholders around the North Coast’s Seaton Interchange was held at the nearby historic Manor House. This milestone marks the commencement of construction on a transformative infrastructure project set to enhance accessibility, drive economic growth and unlock new opportunities for the North Coast.
The Seaton Interchange is a long-anticipated development that will introduce a new south-facing on- and off-ramp to the N2, alleviating congestion, improving traffic flow and providing seamless access to Seaton Estate, Lalela Estate and surrounding developments. Spearheaded by Collins Residential in collaboration with SANRAL this project represents a strategic investment in the future of the region. With a total project cost exceeding R110 million, the interchange is a crucial addition to the North Coast’s infrastructure network.
Geoff Perkins, managing director of Collins, highlighted the project’s significance stating, “This interchange has been a long-needed development for Sheffield area and the surrounding estates, such as Seaton, Lalela and Zululami. This project will unlock a brand-new commercial area creating jobs and driving economic growth. It’s a good-news story all around for the North Coast community.” Beyond easing daily commutes, the interchange is set to stimulate local development, with plans for a new commercial and retail zone and an independent school reinforcing the region’s position as a key economic hub.
Justice Chauke, traffic engineer from SANRAL Eastern Region, emphasized the
importance of this project in addressing growing traffic demands, “Prior to this interchange, traffic congestion was increasing, particularly around the existing interchanges. With thousands of additional trips expected in peak hours due to new developments this infrastructure will help disperse traffic, improve mobility and provide additional capacity for both current and future residents.” Justice also noted that the project supports local economic growth by enabling Small, Medium, and Micro Enterprises (SMMEs) to participate in its development.
Traditional leader Inkosi KaMagwaza expressed appreciation for the project’s inclusivity saying, “This development is not only about roads but about people. Through this project local community members will gain valuable skills and job opportunities ensuring that they can sustain themselves even after construction is completed. We are grateful to the developers for including
us as active participants in this process.” KwaDukuza municipality Mayor, Councillor Ngidi, reinforced the project’s role in regional development. “This interchange is a catalyst for growth, not just in terms of mobility but also in unlocking residential and commercial potential. With enhanced accessibility we anticipate increased demand for housing and business development further strengthening the economy of our municipality. Improved transport links will also boost tourism making the North Coast even more attractive to visitors,” Councillor Ngidi added.
With construction now officially underway the Seaton Interchange is a welcome investment in the future of the North Coast. By unlocking economic opportunities, easing congestion and being a catalyst for sustainable growth this project will reshape the region for generations to come.

AN ARCHITECTS DILEMMA: ENSURING PRINTS REFLECT DESIGN INTENT
In architecture, precision isn’t just a preference, it’s a necessity. A single miscalculated dimension, a misaligned scale or an inaccurate colour rendering in a printed plan can cause costly rework, project delays and, more seriously, even structural issues.
If a contractor misreads faint line weights on a site plan due to poor print quality, it can result in costly mistakes. For instance, a foundation might be poured slightly out of specification, leading to expensive corrections and delays in the project timeline. In an industry where profit margins are narrow and efficiency is key, ensuring the absolute accuracy of printed architectural drawings is essential.
“Architects and engineers operate in a world where even a millimetre can make a difference,” says Joel Chetty, sales manager for C&I at Epson. “Construction drawings, site plans and final construction plans must be accurate and clear produced with precision to ensure all stakeholders are aligned from concept to completion.”
Industry research suggests that errors and omissions in construction documents account for a significant percentage of project cost overruns. A misprinted plan can lead to on-site miscalculations that require extensive rework. Not only does this impact budgets, but it also compromises the integrity of the project and can introduce safety risks. For architects and construction firms this underscores the need for high-quality printing technology that delivers crisp, accurate and durable prints especially as projects become more complex and require greater visual fidelity. High-resolution, colour-accurate output ensures that plans are clear, legible and true to the designer’s intent.
Wide-format printing technology has recently made it easier for firms to maintain accuracy throughout the design and construction process. What’s more, the global wide-format printer market is growing at a 5% CAGR, highlighting increasing adoption in architecture.
The latest generation of precision-driven
wide-format printers, like Epson’s SureColor T-Series, now address key pain points with enhanced resolution, precise colour reproduction and energy-efficient operation.
“Epson’s PrecisionCore technology and UltraChrome XD2 inks enable architects to produce prints that faithfully capture every detail from the finest line weights to the subtlest shading,” adds Joel. “This level of accuracy ensures that all project stakeholders, from designers to contractors, are working from the same, flawless blueprint.”
For architectural firms, investing in reliable printing solutions offers more than just con-
venience, it is essential for maintaining project integrity and efficiency. This is because high-quality prints ensure that every detail from initial designs to final plans, aligns accurately with the architect’s vision. By prioritising precision firms can avoid costly mistakes, streamline collaboration and ensure the successful execution of every project without compromising on quality or timelines.
WOMEN EMPOWERED IN SOUTH AFRICA’S CONSTRUCTION INDUSTRY
A new training initiative by PMI and CIDB equips female entrepreneurs with global project management skills to lead, build, and inspire.
A powerful new training program is opening doors for women in South Africa’s construction industry. The Project Management Institute (PMI) and the Construction Industry Development Board (cidb) have joined forces to offer this special opportunity, helping women gain world-class project management skills and build strong, sustainable businesses in a field long dominated by men.
The program began with five highly accomplished women entrepreneurs. Their selection highlights the importance of choosing experienced professionals who are ready to lead change. Cidb’s CEO, Bongani Dladla explained, “We’re not just offering training for the sake of it. This is about creating a culture of excellence. These women have already proven they have the skills, strength, and commitment to succeed.”
One of the participants, Lulu Ngomane, has worked in infrastructure and construction for years. From managing city development grants to building garages for Shell, she has seen the ups and downs of the industry. “I tried to get certified before but didn’t pass,” she said. “So, when I heard about this chance, I raised my hand immediately. It’s fully sponsored, why wouldn’t I go for it?” Her story reflects the determination and spirit that the program aims to instil.
Phumza Dyani, PMI’s business development lead for the Southern African region, shared the broader vision: “PMI’s global mission is to maximize project success and elevate our world. To achieve this, we must ensure inclusivity and bridge gaps in industries like construction, where women are often underrepresented. This partnership with cidb aligns perfectly with our goal to create equal opportunities and amplify the impact of women in this sector.”
She emphasized the program’s practical benefits: “The training integrates global frameworks like PMP and OPM, tailored to
address South African women contractors’ unique challenges, such as cash flow management, resource allocation and scope creep. By adopting lean and agile methodologies, participants learn to cut inefficiencies, deploy projects faster, and compete internationally. This certification places them on par with their global peers, opening doors to larger projects and cross-border opportunities.”
Phumza also highlighted the role of private sector collaboration: “Private partners can magnify this initiative’s impact by offering real-world opportunities, from projects to mentorship. Our network connects these women with industry leaders, creating platforms for visibility and growth. Success isn’t just about completing the course; it’s about applying these skills to transform their businesses and inspire the next cohort.”
But skills alone aren’t enough. The launch also highlighted some of the unfair challenges women face in construction, like not getting big projects or struggling to access funding.
Award-winning entrepreneur Wendy Mbanjwa pointed out that giving women training is only the first step. “PMI and cidb should also give us real projects where we can prove ourselves. In this industry, your track
record is everything,” she said. Another participant, Leah Ramashala, added, “This program helps me become a better project leader. When you’re truly skilled, people trust you to deliver.”
Beyond personal growth, this initiative is part of a larger mission. cidb’s CEO believes it can help make South Africa a leader in construction across the continent. “If our professionals understand global project language, we can compete internationally,” he said. The program’s pilot phase will test and refine its approach before expanding. Success will be measured not just by certificates, but by how well the women use their new skills in real projects and how many go on to mentor others.
As these women take their first steps on this journey, one message rings clear: this is a chance to build more than just buildings. As Phumza urged, “Take courage and resilience, the rewards are limitless. Construction isn’t just about breaking ground; it’s about the entire value chain. Whether in project management, software, or supply, your contribution matters.” With the support of PMI and CIDB, these women are not only changing their futures, but they are also shaping a stronger, more inclusive construction industry for everyone.

CHRYSO ENHANCES THE AESTHETIC IMPACT OF CONCRETE
With growing demand for buildings that are not only functional but also visually striking, Chryso is helping customers reshape the face of concrete. Driven by technological advancements and a strong appreciation for architectural innovation, the company offers a broad portfolio of solutions that ensure concrete is both durable and beautiful.
According to Michelle Fick, business unit development manager for Concrete Aesthetics at Chryso Southern Africa, customers now have access to a wide range of innovative products tailored to various applications. “To achieve the desired aesthetic impact, it is essential to consider how the concrete is applied,” says Michelle. “That is why we offer a comprehensive suite of solutions, including surface retarders, integral pigments, surface treatments, curing compounds and demoulding oils.”
These products can be used in combination to enhance even the most basic concrete features such as pillars or floors, ensuring
that aesthetics are never overlooked, regardless of the project’s scale or complexity.
One of the most common requirements in aesthetic concrete applications is colour consistency. Chryso’s integral iron oxide pigments provide vibrant durable colour throughout the concrete mass - so even chips or abrasions won’t reveal an underlying colour difference.
Surface quality is another priority. Chryso’s plasticisers and superplasticisers improve the workability and flow of the concrete mix, reducing surface defects and ensuring a smooth high-quality finish. To further strengthen and enhance surface performance, the company also offers densifiers and hardeners that provide improved abrasion resistance. Additionally, its release agents support a clean separation from formwork, enabling a high-class finish with consistent colour and texture.
Texture also plays a vital role in the visual appeal of concrete. Viscosity modifying admixtures like CHRYSO® Quad 20 improve cohesion, preventing issues such as segregation or honeycombing.
Efflorescence - the white powdery residue
that can appear on concrete surfaces - is a common challenge that Chryso tackles with products like CHRYSO Fuge B, an integral waterproofing admixture that blocks pores and reduces the risk of moisture ingress. The company also offers water-repellent surface treatments, such as dry-coat sealers, which prevent water from reacting with free lime - the cause of efflorescence.
Surface finishing is key to consistency, and CHRYSO FiniSafe can be applied just before the final finishing operation to enhance surface uniformity. Michelle stresses that the success of any aesthetic concrete application depends on best practice. “Consistent batch control, quality materials and correct curing techniques are essential,” she says. “We always recommend proper concrete trials before commencing a project, especially for large-scale applications, to confirm the best combination of admixtures and placement methods.”
Chryso takes a collaborative approach, working closely with customers from planning to execution to ensure outstanding aesthetic outcomes. “Our innovations are designed to make concrete beautiful,” concludes Michelle. “But it is our hands-on support that helps customers unlock their full creative and architectural potential.”

INFRASTRUCTURE PROMISES MUST BE BACKED BY PRACTICAL FRAMEWORKS
South Africa’s most important economic driver, infrastructure development, is quickly approaching its golden age. Government again made its commitment to prioritising infrastructure development clear during Minister of Finance Enoch Godongwana’s third National Budget Speech of the year. In it, he earmarked over R1 trillion over the medium-term to infrastructure, while reaffirming that other changes are planned that will help stimulate the sector.
The private sector is in support of government’s vision for the future of infrastructure and service delivery in the country, but clarification would be welcome regarding how, when, and to what extent certain policy changes will be implemented in practice.
For example, the standards governing bids assessments, contractor selection, and funding allocation will ultimately determine how well and how quickly roads are repaired, rail lines are modernised, and water networks are expanded to the benefit of communities across South Africa.
Critically, Godongwana reaffirmed a pledge that substantial changes will be made regarding how projects are selected, financed, and delivered – as already established earlier this year in previous budget speeches that mentioned reforms to public-private partnership (PPP) agreements and budget-allocation structures.
Promisingly, the new PPP regulations were gazetted on 07 February and will take effect on 01 June 2025. These aim to streamline bid processes, permit unsolicited bids, tighten fiscal-risk assessments, and allow departments to set up sector-specific PPP units that will draw in private operators and improve balance-sheet capacity.
A clear outline of how those units will appraise risk and sequence funding would enable contractors to mirror those standards from day one. The Gap Infrastructure Corporation (GIC) therefore recommends an early technical briefing, preferably before the first bids are advertised, to ensure private proposals are calibrated to the same
measures government intends to apply.
National Treasury will also roll out new reforms to standardise project planning and execution across provinces and local authorities, backed by data-driven internal audits meant to weed out under-performing or duplicative programmes.
By streamlining project pipelines and improving internal coordination, Treasury is creating room for faster rollouts and more efficient use of resources. These efforts will help ensure that funds are directed toward high-impact projects that are implementation-ready, enabling contractors to mobilise more quickly. At the same time, improving workforce management and wage allocation will support the development of skilled, reliable teams - empowering private partners to deliver on a broader scale.
Finally, while the R1 trillion medium-term allocation to infrastructure development is substantial, it’s only a portion of what the country will need to make this initiative truly successful. Government cannot carry the full burden, and the private sector must bridge the gap with external funding. Investors are willing to step in, but only when procurement rules are clear and predictable, and risk allocation is well-defined. Fortunately, this is being addressed as well.
Treasury’s Budget Facility for Infrastructure (BFI) reform initiative, which has been in effect since 2016, has been effective in
standardising and regulating the planning, appraisal, and execution processes of largescale infrastructure projects. Government has now reconfigured BFI to consider proposals on a quarterly rather than an annual basis, and with four bid windows per year, contractors can align their project timelines more flexibly while avoiding lengthy delays in securing approvals or financial backing.
Additionally, government plans to issue its first sovereign infrastructure bond in the 2025/2026 period. This aims to attract substantial private-sector capital and provide contractors with access to more predictable and diversified funding sources, potentially leading to more consistent project pipelines and reduced delays due to funding uncertainties.
Taken together, these measures substantially alter the playing field for infrastructure contractors. Government’s support in this regard will ensure that private companies have a far better understanding of expectations, obligations, funding allocations, contractor rights, and consequences of non-compliance. Projects will also benefit from streamlined processes, more coherent timelines, and less red tape hindering progress.
Overall, the latest Budget Speech, seen together with other communications and signs of concrete policy action, thus poses reason for optimism for the sector and, in turn, the entire country’s future.

DRESSING CONCRETE AND CONSTRUCTION PROFESSIONALS FOR SUCCESS
In today’s competitive workplace, image and cohesion go hand in hand and corporate clothing plays a key role in creating both. Concrete Connect sat down with Scott Parritt, the driving force behind South African workwear and uniform specialist Refined Cuts, to understand why dressing your team in high-quality corporate apparel is about more than just looking smart.
Q: What are the most important reasons to wear corporate clothing?
Scott: “Corporate clothing plays a pivotal role in establishing a professional and cohesive identity for businesses. It goes beyond aesthetics it signals consistency, reliability and brand pride to customers and stakeholders alike.”
Uniforms also remove the ambiguity around dress codes and boost team confidence by ensuring everyone looks the part and feels it too.
Q: What are the branding advantages of corporate wear?
Scott: “Branded corporate clothing turns your workforce into walking billboards.”
When your staff wear clothing bearing your logo and colours — whether on-site, during commutes, or at events — you extend your brand’s presence far beyond the office. “It enhances brand recognition and helps reinforce a sense of identity and belonging among employees,” says Scott. “At Refined Cuts, we offer both branded and unbranded options, so businesses can choose what suits their image best.”
Q: How does function play into corporate clothing?
For Scott, it’s not just about appearances — it’s about purpose.
“Corporate and workwear isn’t just about looking smart — it’s built for purpose,” he explains. From breathable fabrics for hospitality staff to reinforced stitching and PPE features for industrial teams, function is a top priority. “We provide tailored solutions that match the specific needs of each indus-
try — from the boardroom to the factory floor.”
Q: How is corporate clothing different from buying clothes in-store?
Scott: “Unlike store-bought clothing, corporate wear is engineered for consistency, durability and brand alignment.”
While fashion retailers focus on trends, corporate clothing is built to withstand daily use, require minimal upkeep and maintain a professional standard. “Our garments are manufactured to meet high-performance requirements, either locally or via trusted imports, which most retail options simply can’t offer.”
Q: Should office and yard/factory workers all wear uniforms?
“Absolutely,” says Scott. “Uniformity across departments strengthens brand identity and reinforces equality.”
Though the styles may differ — with smart office attire for admin teams and rugged workwear for technical staff — the sense of unity is universal. “It signals that everyone, no matter their role, is part of the same mission.”
Q: How can companies justify the cost of clothing their workforce?
Scott: “While the upfront investment may seem high, the long-term benefits are substantial.”
Uniforms reduce wear on personal clothes, enhance staff morale and increase productivity. But most importantly, they boost your brand’s visibility and build customer trust. “We support businesses with a range of options — from premium, locally-made clothing to cost-effective imports — to suit different budgets without compromising on quality.”
Q: What impact does corporate clothing have on team building?
Scott: “Wearing the same uniform can foster a strong sense of belonging and team unity.”
Uniforms help break down barriers, remove visible hierarchies and create a level playing field. “It strengthens collaboration and improves morale,” he says. “At Refined Cuts, we help businesses use uniforms as a tool for building culture and shared identity.”
Q: Tell us about your local operation.
Scott: “Refined Cuts is proudly South African and so is most of our manufacturing.”
By producing locally, the company maintains strict quality control, reduces lead times and supports job creation. “For clients with specific requests or tighter budgets, we also offer imported options from trusted suppliers,” says Scott. “From sourcing to branding and final delivery, we manage everything in-house to ensure a seamless, professional experience.”

HEALTH & SAFETY TRAINING WITH VIRTUAL REALITY
The concrete and construction industry has its fair share of dangers and within the industry the focus is beginning to fall on proactive safety and continuous learning of every aspect that may affect an individual’s health and safety.
Innovative technologies like virtual reality (VR) is proving invaluable in transforming operational practices and boosting preparedness for real-world situations. By offering immersive, realistic high-risk simulations, VR training significantly enhances workplace safety and efficiency, overcoming the limitations of traditional methods.
Recognising the limitations of traditional training methods in simulating real-world hazards, MSHEQ, a division of Stallion Integrated, was the first in South Africa to integrate VR into its safety training programmes. This forward-thinking approach has since been adopted by others in the industry, solidifying MSHEQ’s initial leadership.
“At MSHEQ, we launched our VR training
initiative during the COVID-19 pandemic, a time when innovative learning solutions were paramount,” explains Charné Vosloo, managing director at MSHEQ. We recognised the need to move beyond conventional e-learning and webinars to create engaging and impactful training experiences. Our mindset of Constant and Never-ending Improvement (CANI) drove us to explore VR as the natural next step in health and safety education.”
This strategic move was further validated when MSHEQ received the prestigious Standard Bank Top Women Award for Innovation. While the VR launch followed this recognition, the company’s commitment to ground-breaking solutions was a significant contributing factor. VR technology allows MSHEQ to create realistic, controlled environments that effectively simulate highrisk scenarios. This immersive experience significantly enhances understanding and retention for users compared to traditional methods. Studies indicate a remarkable 75-80% knowledge-retention rate with VR
training, compared to the 20-30% typically seen with conventional learning.
Charné provided compelling examples of how VR training has improved safety outcomes in key sectors:
• Mining: MSHEQ has developed VR modules replicating underground evacuations and machinery operations. This allows trainees to practice critical response skills in a safe environment, leading to more confident and correct actions during real emergencies. One powerful case study involved a crane operator with a previously unrecognised fear of heights who was identified through a VR workat-heights simulation, preventing a potentially dangerous situation. Fortunately, the employee was given an alternate position within the company that was more suited to him.
• Construction: VR modules focusing on fall prevention and site hazard identification have demonstrably improved hazard recognition during on-site audits. Clients have reported measurable increases in compliance scores and overwhelmingly positive feedback from their employees.
• Warehousing and logistics: While initially focusing on retail, MSHEQ has strategically shifted its focus to the warehousing and logistics sector, recognising its significant safety training needs. VR simulations in this area address common hazards and safe operating procedures for equipment and materials handling.
A key differentiator for MSHEQ is its ability to tailor VR solutions to the unique safety challenges of specific client sites.
“Our process often involves sending a video crew to a client’s location to capture the exact environment,” says Charné. “This allows us to build VR worlds that are precise replicas of their workplaces, making the training incredibly relevant and impactful.”
A monitored VR Training session provides valuable insights which could be a risk in a proper worksite.
INSURANCE ADVICE FOR TRAUMATIC INJURIES
Your critical illness cover is there to help you with the additional expenses that come with a serious illness or injury. But does your cover consider traumatic injuries when assessing your claims? Here are some important questions to ask when getting critical illness cover.
1. Should my critical illness cover include cover for injuries?
Yes – injuries are just as likely to result in additional expenses that you haven’t budgeted for as illnesses. Everyone’s at risk of having an accident, even if you’re super healthy. It’s important to consider the impact that a fairly serious injury could have on your finances. For example, falling off your bicycle, hurting your knee and having to go for surgery to repair the joint. If you have medical aid, it will cover most if not all of the expenses around the medical interventions, but what about having to use an Uber to get to and from work because you can’t drive? A medical aid won’t pay for that. That’s exactly what your critical ill-
ness cover is for – to cover the additional expenses that come with suffering a serious illness or injury.
2. If my medical aid covers traumatic injuries, why would I need my life insurance policy to cover them as well? Is this the same as gap cover?
No, critical illness cover is not gap cover – gap cover only covers medical costs not covered by your medical aid plan. You need critical illness, or additional expenses cover to pay for things that your medical aid doesn’t pay for. Say for example you’re diagnosed with cancer and you need to go for chemotherapy. Your medical aid will most likely cover the actual medical treatment. But what about things like taking your children to school and cooking dinner when you’re feeling unwell after your treatment? A pay-out from a critical illness benefit would help with things like hiring some help around the home and transport for your children.
4. What kind of injuries qualify for payouts? Can I get a pay-out if I sprain my ankle?
A sprained ankle probably wouldn’t result in a claim payment as the treatment wouldn’t be invasive or long-lasting. If you broke your ankle badly and needed surgery with some physiotherapy afterwards to make sure that it healed well so that you can walk and run again properly, this would be more likely to trigger a Trauma IQ claim at BrightRock as this would be likely to come with additional expenses.
3. What do I need to do to qualify for pay-outs for traumatic injuries? Can I treat my injuries myself at home?
For a small injury, you can definitely treat it at home and put on a plaster, but these types of injuries would not be severe enough to qualify for a payment from your life insurance policy. An insurer would consider a payment for an injury where the injury is quite serious and needs to be treated at least in an emergency room, or by a qualified doctor. These are the types of injuries that would result in additional expenses that you didn’t anticipate and that could result in a Trauma IQ claim payment at BrightRock.
5. Do all insurance companies cover traumatic injuries?
Even though current naming conventions don’t seem to suggest this (critical illness cover, dread disease cover, etc) most life insurers would cover injuries, but generally only those that are really severe such as burns to a significant portion of your body and permanently losing the use of limbs because of an accident. Only BrightRock covers accidental events that are lower in severity but still have an impact on your pocket, like an Achilles tendon repair after playing padel or hurting your arm badly after falling off some rocks at the beach.
6. How serious does the injury need to be to qualify for a payment?
At BrightRock, the injury needs to be bad enough that you seek medical help within four weeks of the date that you hurt yourself. It also needs interventions such as surgery, or hospitalisation, or rehabilitation. We look at nine different factors to assess how serious the injury was in terms of the interventions needed to fix you up again.

KNOW HOW TO RESOLVE CONCRETE DISPUTES
Did you know that disputes over incorrect readymix concrete deliveries can be complex and costly?
When large sums of money are involved in removing or remediating already set concrete, resolving claims efficiently becomes crucial.
Many believe that testing before, during and after delivery is the ultimate safeguard for quality assurance. However, other critical factors also play a role in determining liability and ensuring the success or failure of a claim against a readymix manufacturer.
Concrete-related disputes can quickly turn into a blame game due to differing interpretations of standards, legislation and testing methods. To prevent misunderstandings it is vital to work with written specifications that outline the exact mix ingredients, required strengths and other key factors.
Reputable concrete suppliers should adhere to industry codes of good practice while ensuring a clear paper trail and nec-
essary test results to verify compliance. It is also essential for readymix companies to strictly follow these specifications and perform all legally required tests to avoid potential disputes.
A smooth working relationship between the supplier and customer is just as important. Deliveries must be timely and a prepared workforce should be on-site to handle the concrete correctly upon arrival. While anyone can mix concrete, quality assurance is far more reliable when working with properly accredited suppliers who undergo regular audits.
Did you know that no claim will hold up without proper documentation?
Treating any dispute as if it were a legal case from the outset can help prevent matters from escalating to court.
A valid claim requires a specification and proof of breach. If specific requirements are needed they must be clearly stated upfront otherwise proving non-compliance be-
comes difficult. In any dispute all involved parties including the customer, contractor and readymix supplier must be included in the resolution process. Costs cannot be escalated unfairly nor can delays be used to shift financial burdens.
Most readymix suppliers include disclaimers that protect them from consequential losses. As a result claims are generally limited to direct losses resulting from faulty concrete and only when all other remedial options have been explored.
Did you know that concrete testing requires highly specialised procedures?
These must be meticulously controlled to ensure a claim’s success. The burden of proof rests with the claimant who must demonstrate beyond reasonable doubt that the delivered concrete does not meet specifications.
All tests must be conducted according to South African Bureau of Standards (SABS) procedures. Factors such as curing conditions, temperature control and correctly calibrated testing apparatus play a significant role. Failure to adhere to these procedures will likely result in the dismissal of a claim.
However, disputes can often be avoided altogether by agreeing on clear specifications, following proper testing methods and implementing best practices. If issues arise all parties should work towards resolution before considering legal action.
Did you know that with the right approach concrete disputes can be managed efficiently, saving time, money and resources?
AFRISAM UPGRADES RHEEBOK QUARRY WITH SANDVIK CH430 CRUSHER
AfriSam has enhanced its Rheebok Quarry operation with the installation of a high-capacity Sandvik CH430 cone crusher from Sandvik Rock Processing. The upgrade ensures reliable safe production with reduced maintenance and a lower carbon footprint.
Located near Malmesbury in the Western Cape, the granite quarry produces a range of materials, including aggregate stone, crusher sand, roadstone and ballast. According to Desmond Jacobs, AfriSam’s senior engineer for the Western Cape, this investment aligns with the company’s longterm capital strategy.
The decision to install the Sandvik CH430 was driven by key features such as its hydraulic Hydroset system and Automatic Setting Regulation (ASRi) system, both of which enhance performance and streamline maintenance. The Hydroset system enables precise automated closed-side setting adjustments, while the ASRi system continuously monitors and optimises crusher performance.
“We appreciate how the Sandvik CH430 minimises operator intervention allowing
real-time adjustments to the closed-side setting,” says Desmond. “This improves product size consistency and quality. The system also tracks key parameters like temperature and pressure, enabling proactive maintenance and reducing unexpected breakdowns.”
He notes that the new unit has already demonstrated its impact on product quality by reducing oversized material in the feed stream.
“Our initial assessments showed a dramatic reduction in oversize material being sent for secondary crushing, This allows us to optimise throughput and potentially eliminate redundant processing steps in the future.”
A crucial factor in selecting the Sandvik CH430 was its compact footprint which closely matched the previous crusher. “As a brownfields project, we had to work within existing site constraints,” Desmond explains. “Matching the footprint was essential as we had limited time for installation and could not accommodate extensive structural modifications.”
PC Kruger, Business Line Manager for Crushing Solutions at Sandvik Rock Processing, highlights the Sandvik Plant Designer platform which helped optimise the model selection process. Additionally, the energy-efficient crusher, powered by a 132kW motor, aligns well with AfriSam’s specification, contributing to lower energy costs and reduced carbon emissions.
With a local office and warehouse in Cape Town, Sandvik Rock Processing ensures AfriSam receives prompt technical support, spare parts and plant audits whenever required.
A Sandvik CH430 cone crusher has been installed at AfriSam’s Rheebok Quarry to improve efficiency, product consistency and energy consumption.
The Sandvik CH430 offers flexibility with interchangeable mantles and concaves, allowing AfriSam to meet varied product specifications.
A SOUTH AFRICAN LOOK AT CONCRETE TESTING
Concrete. Some think it’s just a concoction of cement, sand, stone and water, something you slap into a hole to keep a gate post upright or pour for a patio where you can kuier with a Klippies and Coke. But in truth, it’s one of the most quietly brilliant materials on Earth. It doesn’t shout for attention, it’s not glamorous and most people don’t realise just how technical it is. But look around, chances are, something within arm’s reach is either made from concrete or sitting on top of it.
It’s everywhere. Sidewalks, bridges, buildings, stadiums, even the mall floor that your kids use to skid across in school shoes, it’s all concrete. In fact, it’s the second most consumed material in the world, right after water. And still, it gets less recognition than the car guard who expects a tip after watching your car for exactly one minute.
So then, what is concrete really?
Think of it like a Christmas cake. Not the boxed kind, but the proper one your gran used to make. Concrete is the final product of carefully combined ingredients, cement (your flour), water (your milk), sand and
stone (your sugar, nuts and dried fruits).
Get the mix right and you’ve got something solid, dependable and built to last through any weather, just like gran’s Christmas cake, which somehow survives for years. But get the ratios wrong and you’re left with a weak, cracked or sad concrete slab… or, in cake terms, a sad, sunken mess so bad even your dog skeefs you out.
Concrete Mix Designs
To avoid that kind of disaster, you need a proper recipe or what we call a mix design. It’s your blueprint for making the exact type of concrete you need, whether you’re building a driveway, a dam wall or just trying not to repeat the Great Cracked Patio of 2021.
A mix design is a guide to getting the right balance of materials: cement, water, fine aggregate (like sand), coarse aggregate (like stone) and admixture. The mix isn’t just about making something hard; it’s about getting the right kind of hard. Whether you need concrete that can handle heavy loads, flow easily into complex formwork,
survive freezing winters or just look smooth enough for a polished floor, the mix design sets the stage. Understanding the type of concrete you need helps with the design of the mix. Key factors in a good mix design include:
• Strength requirements – How much load it needs to carry without cracking like a dry rusk.
• Exposure conditions – Will it face rain, chemicals, salty air or just the occasional spilt beer?
• Workability – Can you actually pour and shape it without a wrestling match?
• Durability – Will it still hold strong 1030 years from now like grans Christmas cake?
• Economy – Getting the performance you need without breaking the bank or over-engineering it like a government tender.
Once we know what kind of concrete we need, the next step is to look at the mate-
rials we’re working with. You can’t expect top-quality concrete if you’re using second rate ingredients. It’s like trying to bake a cake with expired milk and self-raising flour that’s lost the will to live. We need to understand the qualities of each material, cement, sand, stone and water before we can create a reliable mix design. The better we know what’s going in, the better the concrete comes out.
Defining the right type of concrete and using quality materials in the correct ratios, that’s what a mix design is all about. It’s the recipe that tells you exactly how much of each ingredient to use, by weight (or occasionally by volume), to get the performance you need. No guesswork, no shortcuts, just a proper plan to make sure your concrete actually does its job.
Consistency, consistency, consistency
Let’s say you’re helping your mate build a concrete braai area over two weekends. The first batch? Spot on. Smooth, strong, easy to work with and everyone’s impressed so far. But the next weekend, you get a bit creative: add extra water “just to make it easier” and toss in some mystery stone you found behind the shed because you ran out of the proper stuff. That second batch sets weird, starts cracking and now your mate’s giving you the side eye every time he flips a chop.
Even small changes, like a slightly wetter mix or switching to a different stone can mess up the mix. Concrete doesn’t forgive, it remembers.
So, how do you keep it consistent? Good news: there’s a process for that.
Use the same consistent materials
If you change the cement, sand, stone, admixture or even water, you need a new mix design. Full stop. You can’t just swap things out halfway through a job and hope for the best. That’s like suddenly using almond milk in your rusk recipe and expecting no one to
notice. They will. And they’ll be upset.
Stick to the same suppliers, same sources and same specs unless you plan to redesign everything.
Control the moisture in your sand
Sand holds water. If it rained last night, your “perfect mix” could suddenly turn into concrete soup. That’s why moisture control is critical.
Here’s the rule of thumb I give clients:
Check the moisture in your sand every morning, after rain, after any new delivery and every afternoon. The more accurately you monitor moisture, the more consistent your concrete will be.
Do simple moisture tests and adjust your water/sand content accordingly. A little effort here saves a lot of stress and failures later.
Measure, don’t guess
Yes, actually measure. Not “a bit of this and a touch of that.” You’re not making a salad. Concrete needs precision.
Follow the mix design and weigh your materials accurately, cement, sand, stone, water, the works. Too much sand? Your mix will need more water. More water? Less strength.
Accurate weighing and measurement is key to consistent concrete. And don’t forget your scales, make sure they’re calibrated regularly by someone who actually knows what they’re doing. Not your cousin with a screwdriver and YouTube.
Mix properly
None of this “give it a swirl and hope” nonsense. Get a proper mixer or a very committed friend with strong arms and no plans for the weekend. If you’re using a truck, make sure the blades aren’t worn down to nothing. Ensure the mix is properly blended and uniform from top to bottom. You don’t
want one wheelbarrow of stoney sludge and the next full of sloppy soup from the same batch.
Testing, testing, 1-2-3
Slump tests and cube tests aren’t just box ticking exercises, they’re your early warning system. Do them and do them often. The more test data the merrier.
If your concrete looks suspiciously like pancake batter, take it as a red flag, something’s not right. And if your cube strengths are all over the place? Something’s gone wrong, go back and check your mix, your materials, your moisture, your weighing, your mixing or even your testing. Somewhere along the line, you’ve slipped.
Testing gives you peace of mind. It proves your concrete is performing like it should and gives you the confidence that you’re not just pouring expensive porridge. Think of testing as a small investment that could save you from big disasters and even bigger repair bills.
In the end, concrete isn’t complicated
Concrete might seem like just another building material, but as you’ve now seen, there’s a whole science (and a bit of common sense) behind doing it right. Get the mix design right, use good quality materials, keep everything consistent and test like your project depends on it (because it does). Whether you’re building a hospital, a mall, a home or just a humble braai spot, good concrete is no accident. It’s measured, managed and mixed with purpose. Skip the shortcuts and you won’t just save yourself from cracks, you’ll save your wallet and your reputation.
Still unsure? Call the pros.
As simple as it all sounds, if you’re still unsure, call in the experts. We’ll help you get it right the first time, save costs and avoid becoming the next concrete horror story your colleagues joke about at braai’s.

SMARTROCK REVOLUTIONISES CONCRETE MONITORING IN SOUTHERN AFRICA
Concrete monitoring is undergoing a quiet revolution with the use of data generated by specialised sensors that are embedded within concrete structures where they can continue to generate curing information for up to four months.
Supply Five in Cape Town is the sole authorised distributor of Giatec’s SmartRock concrete sensors which are increasingly being used by local contractors, engineers and precast manufacturers, providing them with a smarter way to build. The sensors form part of the company’s specialised product range that includes other construction essentials such as shutter ply, plywood, fibre cement products, concrete repair, waterproofing materials and formwork components. Supply Five’s experience in supplying critical components to the formwork and concrete sectors is what led the company to this smart technology and is the reason for its rapid uptake, especially for critical and complex concrete pours.
According to Supply Five general manager, Marlene Bradnick, SmartRock is a compact, wireless concrete sensor developed by Canadian firm, Giatec, a global leader in digital concrete technology platforms. These sensors are embedded directly into concrete and use the ASTM C1074 maturity method to measure internal temperature and calculate concrete strength development in real time.
Unlike traditional methods, which rely on time-consuming cube testing and lab results, SmartRock gives contractors instant access to strength and temperature data on their smartphones or tablets without the
need for external wires or expensive data loggers. The device is small enough to fit in the palm of a hand, yet powerful enough to track both core and surface temperatures for accurate differential measurements.
In the real world, this allows site managers and engineers to strip formwork earlier and more confidently while eliminating the cost and delays of lab testing. This allows the optimisation of construction schedules and the use of manpower and in the long-term, it reduces the risk in structural elements such as piers, bridge decks and mass foundations among others.
From high-rise commercial developments in Johannesburg to mining shotcrete applications in the Northern Cape and wind turbine foundation on the coast the SmartRock sensors are already being widely used in Southern Africa. Other applications include mass concrete pours such as dam walls and bridge piers, precast manufacturing of high-strength elements like vaults and battery enclosures, high-performance infrastructure like data centres where early strength verification is essential.
“SmartRock’s biggest value proposition lies in its ability to replace traditional early-age cube testing. By providing real-time strength data from within the concrete pour contractors can avoid unnecessary delays,
Supply Five general manager, Marlene Bradnick
optimise curing processes and make decisions faster all while cutting costs on cube moulds, break tests, lab fees and transport. The return on investment is typically realised within the first few uses. It pays for itself by enabling smarter, faster construction,” says Marlene.
She continues that Giatec’s SmartRock sensors, combined with advanced software solutions, allows users in South Africa to benefit from free mobile apps (iOS and Android) for setup, monitoring and analysis, as well as online product training and documentation with regular software updates and cloud integration for project teams.
This enables contractors and engineers to have access to the tools they need to implement SmartRock effectively without requiring specialised skills or additional hardware. Its usefulness has also encouraged Supply Five to expand the reach of SmartRock across Southern Africa and work with engineers and regulators to advocate for the inclusion of maturity-based concrete monitoring in standard specifications. This would bring South Africa in line with global best practices and improve the quality and efficiency of concrete construction across the region.
long-term cost savings can outweigh this
costly mistakes or rework, owners can save complicated to implement?
“These sensors have been successfully used in over 13,500 projects in 85+ countries and is within easy and affordable reach of Southern Africa’s construction professionals,” Marlene concludes.

POLYMER BEARINGS PROTECT CONCRETE EQUIPMENT
A new generation of polymer bearings are extending equipment life, eliminating lubrication and slashing maintenance of agricultural machines and doing so without the use of potentially contaminating lubricants.
It is no secret that concrete equipment must withstand harsh conditions like abrasives, corrosion, moisture, vibrations and heavy loads where heavy-duty traditional metal bearings require regular maintenance and continuous lubrication. This is not the case with the latest heavy-duty polymer bearings from igus which exceed metal bearings in terms of durability, efficiency and smoother operation.
According to Juan-Eric Davidtz of igus South Africa, the company’s iglide polymer bearings have turned the market on its head in recent times with dry (built-in) self-lubricating bearings that were once thought im-
possible. They significantly improve performance, last longer and eliminate the need for external lubricants that can attract dirt and cause wear. This feature is especially beneficial in dusty environments, where traditional lubricated bearings can fail prematurely due to contamination.
“The longevity of igus bearings is well-documented and some of the longest lasting ones are going on 20 years using iglide bearings. These bearings have endured extreme stresses from high impact loads to varying temperatures without the need for maintenance. Apart from their durability polymer bearings offer significant advantages in terms of shaft protection. Unlike metal bearings which can cause shaft damage over time igus bearings are softer than steel shafts and therefore do not wear these potentially expensive components.
“Even noise is reduced and the polymers’ inherent vibration-damping properties result in quieter machinery operation which is a feature appreciated in fieldwork and processing environments. In concrete applications pollutant control is paramount and the greaseless operation ensures unblemished finishes. They are also resistant to chemicals, acids and temperature fluctuations which ensures they meet requirements of equipment manufacturers,” explains Juan-Eric.
He adds that by cutting the need for lubrication and reducing maintenance downtime our equipment suppliers and concrete manufacturers can achieve significant cost savings. Additionally, the lightweight nature of polymer bearings contributes to overall machinery efficiency and can even reduce energy consumption.
PRECAST CONCRETE PANELLING CONVERTS WAREHOUSE INTO VIBRANT RECREATIONAL SPACE
Load-bearing precast concrete panels supplied by Concrete Manufacturers Association (CMA) member, Cape Concrete Works, have given The Foundry, 60-year-old two-storey light-industrial building, a new lease on life. Twelve arched precast panels have replaced plastered masonry walls on the building’s two main facades, radically transforming a stark structure into a modern, light-filled consumer and commercial space.
The Foundry is situated in Nooitgedacht Village, a secure lifestyle village some 10km from the centre of Stellenbosch. Developed by Remey Property Group, the revamped structure houses all the amenities needed in a secure lifestyle village including a restaurant, fully equipped gym, offices, a pre-school, laundromat, doctors’ rooms and five airbnb units.
The building is located in a pocket of undeveloped land which Remey bought in 2022. Besides The Foundry, The Vineyards, a new apartment block built by Remey some 40m away, the Village includes 385 homes, development land and some old warehouses which are also earmarked for redevelopment by Remey.
The Foundry’s makeover design and the use of precast arched panels was initiated by Remey Construction’s experienced project team in collaboration with Gass Architecture Studios, which designed the building, and KLS Consulting Engineers, which handled the structural engineering. Remey Construction, which forms part of Remey Property Group, was the main contractor, and in addition to casting the precast concrete panels, Cape Concrete was responsible for the panel installation.
“When taking all the new walling elements into account, precast concrete worked out to be slightly more cost-effective than castin-situ walling,” said Remey contracts manager, Dawid Adendorff.
“Time was of the essence because we wanted the completion of The Foundry and The Vineyards apartments to coincide, and by opting for precast rather than cast-in-situ panelling we were able to cut construction time by four weeks.
“Besides the advantage of precast’s superior finishes, another was that all the panels would be delivered with identical dimensions. This meant that the aluminium window and door-frames could be ‘mass-produced’ to a single set of measurements rather than 12 different sets had the panels been cast in-situ. Moreover, Cape Concrete handled the full panel installation which allowed our foreman to devote more time to other aspects of the project.”
“A project of this nature demands the stringent and robust application of all OHS elements, and this is a facet of our work to which we always pay particularly close attention. And it’s worth noting that during the 2024 Boland Master Builders Association AGM, Remey Construction won an award for exceptional Occupational Health & Safety standards for projects in excess of R40 million.”
Architect Zach Botha said that regeneration projects in which a building’s core elements are left intact form an important part of Gass Architecture Studios’ product offering.
“Our initial approach to The Foundry project was to erect the arched façade walling
with in-situ concrete, but we found that precast gave us great quality control and the precise finishes we wanted.
“It was important for us to open up the building and our design centred on the user and pedestrian. To this end we created a double-volume central spine which provides access to all ground-floor activities. It has two entrances, each framed by two of the panels in opposing elevations. And by introducing arched panels with a high percentage of glass frontage we were able to fill the building with natural light.
“We retained the roof and most of the first floor in the revamped structure, the former because its exposed wooden rafters form an attractive architectural feature,” said Botha.
Cape Concrete cast the panels in three sections, an upper arch section in a single unit with two load-bearing beams, one above the arch and the other below it, and two columns which are bolted to and support the arch sections. The lower beams were indented on the outer panel facades by 30mm so that an infill of klompie cladding could be attached to them for aesthetic purposes.
The assembled panels weigh nine tonnes apiece, are 6.5m high and have a column-to-column width of 5m. This made them too large for normal transport, a challenge which was solved by assembling them on site.
The building incorporates a first-floor slab reinforced with down-stand beams and columns at five metre centres, as well as internal and perimeter load-bearing masonry.

“We had to design for the lateral and vertical loading on the panels. We opted for a propped cantilever design in which the panels were laterally supported in mid-section by the first-floor slab. Additional support was gained by a specially designed connection system which tied the panel columns to the foundations and which provided moment transfer to the foundations,” said structural engineer, Christie Schreuder of KLS Consulting Engineers.
“Site work began with propping the first floor down-stand beams along the perimeters of three facades as well as the roof framework so that the perimeter walls, which were load-bearing, could be demolished. In addition, during construction the roof was propped and the first-floor internal walling left intact for additional support until the loading could be transferred to the precast panels and to longitudinal steel I-beams which were mounted on hollow steel sections.
“One of the challenges facing the project
team was the fact that the roof eaves overhang the two elevation walls. This meant that the mobile crane could not lower the panels directly onto rebar or anchor bolts as is customary. Rather, they were lowered onto the foundations at an angle and then tilted into a vertical position. And instead of being bolted or dowelled to the foundations, they were wedged between two 500mm high concrete upstands.
“The first or inner upstand was cast before the panels were installed and the outer unit was cast once the panels had been propped into position. Non-shrink grout was poured into the gap between the panel support columns and the two upstands. By providing moment transfer to the foundations this connection system further strengthened the structure’s lateral stability,” said Christie.
In order to hang the panels in a vertical position, Cape Concrete fabricated two steel brackets which were attached to the top of the panels on either side of the arches.
They were reinforced with a connecting steel beam and followed the contour of the roof eaves when the panels were hung in their final vertical resting position.
Before the panels were lowered into position Cape Concrete took levels on all the foundations. Steel shims were then placed between the foundations and the panel columns, and because the panels were installed at an angle, extra-long shims were used to prevent any shifting during the installation process. Once the panels were adjusted to the right height they were propped at 60°.
The lower beams in the arched sections were attached to the first-floor down-stand beams and the upper beams were connected to the roof rafters, both with U-shaped steel brackets.
You are invited to visit Nooitgedacht Village to sample the atmosphere created by these faultless arches and experience what “live life beautifully” is all about.

STORMWATER PIPES FOR ZIMBABWE PROJECTS
Tefoma Construction selected Rocla’s Spigot and Socket stormwater pipes for use on the Mbudzi Interchange Project that is currently being constructed south of Harare in Zimbabwe.
Robert Hill, sales manager for Infrastructure Specialist Group of companies (ISG) which includes South Africa’s Rocla said “Our Spigot and Socket stormwater pipes were selected for this project due to Rocla’s reputation for the design and manufacture of high quality and durable stormwater solutions. The Spigot and Socket system is specifically designed to handle high-pressure environments while maintaining their structural integrity despite any demanding conditions”.
“We know that Rocla products undergo rigorous quality assurance testing in order to comply with industry standards and this makes them a highly recommended source of supply. Both the Harare City Council and the project consultant approved Rocla’s Spigot and Socket option. No project is without its challenges and there were a few logistical issues that had to be overcome in the delivery of the pipes, but Rocla’s team ensured that they were delivered on time “said Chris Muzondo, commercial manager of Tefoma Construction.
The original Mbudzi Roundabout had become an inefficient and outdated traffic system. As a result, the Zimbabwe Government’s Ministry of Transport and Infrastructural Development has embarked on a project to develop a modernised Mbudzi traffic interchange in order alleviate severe congestion and reduce travelling time. The Mbudzi Interchange Project entails the modification of the Mbudzi Roundabout with the development of a flyover and which includes the building of 15 bridges with 13 directly on the interchange itself.
“We supplied 29 x 1200mm pipes and 29 x 1350mm of 100D Spigot and Socket stormwater piping which in total measured 141 meters, which we believed was the ideal stormwater solution for such a large and complex piece of infrastructure development. The Spigot and Socket design ensures easy installation with a reliable watertight connection that minimises the risks of leaks making them the perfect choice for such projects,” said Robert.
The Spigot and Socket pipes comprise a rubber ring joint pipe which is a watertight pipe for use in sewer applications where aggressive groundwater is kept out of the system, or aggressive system contents are kept within. The Spigot and Socket type
joint is formed with a widening of the wall of the pipe on the one end.
Rubber ring system used compromises a rubber “O” type ring, which is located on the tip of the spigot end of the pipe. When the pipes are joined the rubber ring is compressed and rolls away from the tip down the barrel.
No lubrication is required nor should it be used. The seal is formed between the socket (or female end) and the outside of the spigot (or male end). Stormwater and sewer pipes are manufactured and tested according to the requirements laid out in SANS 677 (concrete non-pressure pipes) and SANS 676 (concrete pressure pipes).
The pipes are supplied in lengths of 2,44m or 1,22m and in 50D, 75D and 100D strength classes. Customised special strength designs can be accommodated. Rocla Spigot and Socket stormwater solutions have also recently been applied to the main sewer line repairs at Queen Nandi Drive, KwaZulu Natal after recent flooding in the area, as well as to projects in Cape Town and Mozambique.
HOW TO LAY A FOUNDATION FOR A DIY BOUNDARY WALL IN CLAY GROUND
For the DIY enthusiast laying a stable and durable foundation for a boundary wall or fence in clay ground presents unique challenges that require technical planning and execution.
Clay soils are known for their high plasticity and moisture content making them prone to expansion and contraction due to seasonal weather changes. These characteristics can lead to ground movement with a risk to any structure built on top. Without proper design and preparation boundary walls or fences built on clay can crack, tilt or collapse over time.
This article is based on accumulation of knowledge and material from a variety of sources and serves as a guideline only of the best-practice methodology for preparing, designing and laying a reliable foundation for a boundary wall or fence in clay soil.
Before construction begins it is essential to assess the type of clay on site. Clay soils can be classified as:
• Expansive clays (active clays): These exhibit high volume change with moisture variation.
• Low-plasticity clays: These have lower shrink/swell potential.
• Collapsible or dispersive clays: These weaken structurally when saturated.
In most residential and light commercial projects the concern is expansive clay which can move significantly between wet and dry seasons. The movement causes differential settlement and heaving which are both detrimental to wall stability.
Soil testing is strongly advised to determine plasticity index (PI), moisture content and bearing capacity. Based on these results, engineers or experienced contractors can decide on the depth and type of foundation required.
Step 1: Site clearance and preparation
Start by clearing the line of the fence or wall from vegetation, topsoil and organic material. Clay soil holds water, so site drainage is a top priority:
• Grade the area to allow runoff.
• Avoid ponding of water near the future wall.
• If necessary, install temporary surface drains.
Mark the boundary accurately using pegs and builder’s line or GPS coordinates if required.
Step 2: Foundation design principles for clay
Unlike sandy soils clay requires foundations that go below the active zone – the zone affected by moisture changes. In South Africa, this can be anywhere from 600 mm to 1.5 m deep, depending on the soil class and climatic conditions.
Recommended foundation options for boundary walls or fences in clay include:
A. Deep Strip Foundations
• Suitable for solid masonry or precast panel boundary walls.
• Typical dimensions: 600 mm wide x 700–1200 mm deep, depending on wall load and soil report.
• Reinforced with steel bars to resist tensile forces from soil movement.
• Base layer of 75 mm concrete blinding may be added to level the trench.
B. Pad and plinth footings for fences
• For steel palisade, bar or mesh fencing, use reinforced concrete pads or plinths.
• Post footings should extend at least 800–1000 mm deep in clay.
• Footings must be isolated (non-continuous) and spaced evenly along the fence line (usually every 2–3 m).
• Expansion joints may be needed between pads.
C. Stiffened raft foundations (for very active clays)
• Used in cases of extreme clay movement or for retaining-type walls.
• Incorporates horizontal and vertical reinforcement to resist differential heave.
Note: A structural engineer should be consulted when designing walls over 1.8 m in height or where the foundation must act as a retaining system.
Step 3: Excavation of trenches
Excavate the trench to the required depth. Take care to:
• Cut to a flat, level bottom.
• Remove any loose or wet soil.
• Avoid over-excavation, which can lead to foundation slumping.
For long runs, excavation should proceed in sections to prevent collapse, especially after rain.
Step 4: Drainage and moisture management
Because clay retains water, poor drainage can compromise your foundation. Key drainage solutions include:
• Weep holes through the wall base if built on a slope.
• Subsoil drains (French drains) adjacent to the trench, wrapped in geotextile fabric.
• Compacted gravel layer (150–200 mm) under footings for some pad foundations.
Clay also dries and cracks in droughts.
Maintaining consistent moisture around the foundation reduces movement. This can be achieved by:
• Laying a moisture barrier like plastic sheeting (not under the footing, but along the sides).
• Ensuring landscaping and irrigation are placed at least 1 m away from the wall.
Step 5: Reinforcement and concrete pouring
Reinforcement is essential in clay soils. Typical reinforcement for strip foundations includes:
• Two rows of Y12 rebar, top and bottom, with stirrups every 300 mm.
• Steel placed on spacers or concrete blocks to maintain cover.
• Bars tied with binding wire and overlapped by 500 mm if longer than 6 m.
For fence posts:
• Insert the posts into the centre of the hole with braces.
• Pour 20 MPa to 25 MPa concrete mix with a slump of 75 mm for workability.
• Vibrate or tamp concrete to eliminate air pockets.
Let concrete cure for at least 7 days before loading (e.g., placing panels or fixing gates).
Step 6: Building the wall
Once the foundation has cured:
• For masonry walls: Lay blocks or bricks with expansion joints every 4–6 m.
• Use DPC (damp proof course) at least 150 mm above ground.
• Apply a waterproof coating to the base where needed.
• For fences: Bolt or weld panels to posts, ensuring verticality.
• All steel components should be hotdip galvanized or coated.
Step 7: Backfilling and Finishing
Backfill the trench with selected material preferably coarse sand or gravel and compact in 150 mm layers. This reduces pressure on the foundation and promotes better drainage.
Slope the final backfill away from the wall to prevent water accumulation.
Optional finishing touches:
• Plastering and painting walls.
• Installing coping or capping for waterproofing.
• Landscaping with groundcovers that don’t require heavy watering near the base.
Maintenance Tips
Even the best foundation in clay ground can be affected by extreme weather. Key maintenance includes:
• Check for cracks or tilting annually.
• Keep moisture levels consistent by avoiding sudden wetting or drying.
• Prevent tree roots from growing near the wall.
• Inspect and maintain drainage systems regularly.
Remember, building a boundary wall or fence on clay ground requires more than just digging and pouring concrete. It demands an understanding of soil behaviour, appropriate foundation design and proper drainage. With good planning and quality materials, your structure can withstand the challenges of clay soils and last for decades.
Always consult a geotechnical expert or structural engineer for walls that exceed typical heights, carry loads or are exposed to heavy winds or water runoff.
POPULAR BAKKIE MEETS A NEW MILESTONE
Mahindra South Africa recently celebrated a major milestone with the delivery of its 20 000th South African assembled Mahindra Pik Up during a special ceremony at its facility in Durban.
The ceremony was attended by dignitaries from South Africa and India, the leadership and management team of Mahindra South Africa as well as staff from the group’s South African head office and from the assembly facility itself. The attendees included the High Commissioner of India to South Africa, the honourable Shri Prabhat Kumar, the consul general of India in Durban, Dr Thelma David, Rajesh Gupta, the CEO of Mahindra South Africa and Corrie Kotze, the CEO of AIH Group, Mahindra’s production partner.
The 20 000th milestone follows six years after Mahindra opened its assembly facility on 25 May 2018. In these early days, Mahindra set a goal of producing 2 500 Pik Up models per year which it has exceeded that goal by a factor of four.
At the celebrations, a special Pik Up S6 4×4 shared the stage with dignitaries. Mahindra first started producing single cab Pik Up models at the plant before increasing the plant’s capabilities and the complexity of its semi-knocked down (SKD) line to reach a point where each Pik Up is a complete nuts and bolts assembly.
Over time, Mahindra South Africa added its double cab and special edition models, such as the very popular Karoo Editions to the line-up and today all Pik Up models are assembled here.
“The Mahindra Assembly Facility could rightfully be described as the largest and most complex of its kind on the African continent if one considers single-brand facilities that produce a consistent flow of vehicles every month,” says Rajesh Gupta, CEO of Mahindra South Africa.
Supporting Mahindra South Africa’s assembly plans is AIH, a Level 2 BBBEE Empowered company that operates the Assembly
Facility on behalf of Mahindra.
“AIH and Mahindra have worked closely together to increase the production output and complexity of the facility. All the intellectual property that we have generated by constantly improving our plan is shared with Mahindra for use in other similar facilities across the globe,” says Corrie Kotze, CEO of Auto Investment Holdings Group (AIH Group).
Mahindra and AIH will soon enter the next phase of its journey by starting production on a brand-new assembly facility. This facility will cover 14 000 m2 and will redouble Mahindra’s investment in the country.
Construction of the new assembly facility is expected to be completed by June 2025 at which time the company will expand its staff complement to meet the growing production volumes. At present, Mahindra employs 90 staff on the assembly line.
The new assembly facility will anchor Mahindra’s next growth phase in South Africa.
“The assembly facility has allowed us to not only meet the growing local demand for Pik Up models, but to also serve the needs of the South African bakkie buyer. For instance, the Pik Up Karoo Dusk, Dawn, Storm and Dew Special Edition models are made possible by the assembly plant,” says Rajesh.
Mahindra is the second largest seller of single cab bakkies, as well as the fourth largest bakkie retailer overall. This is a far cry from the early days when Mahindra sold its Bolero and later its Scorpio SUV through a small number of local dealers.
Mahindra South Africa first opened its doors in October 2004 when representatives from Mahindra & Mahindra opened an office in Pretoria, Gauteng and welcomed its first local team members.
Since those first days, the company has grown its vehicle range, its dealer network and its supporting infrastructure to levels
that can match that of many other local manufacturers. This has been in keeping with its stated goal of making South Africa the second home for Mahindra outside of India.
And while Mahindra has never pursued growth for its own sake, it has seen its sales and operations grow exponentially in the last six years. In 2019 and 2022 Mahindra was recognised as the fastest-growing brand in the country and it has counted among the fastest-growing brands overall since 2018.
Mahindra increased its investment to keep pace with its growth, opening a new multi-storey parts warehouse in Johannesburg, a new high-tech training facility in Centurion and a Special Fitment Centre in Kempton Park.
The Fitment Centre allowed Mahindra to introduce special edition models such as the popular Karoo and Karoo Dawn, Dusk, Storm and Dew special editions. The production of the Karoo range has since been moved to the Mahindra Assembly Facility, where it is built alongside the complete range of single and double cab Pik Ups.
Speaking at the special ceremony the High Commissioner of India said: “India and South Africa are major trading partners and nowhere is this more evident than in the automotive industry. Mahindra is a perfect example of the increase in trade and investment between the two countries, growing in local popularity while constantly increasing its investment in South Africa.
“South Africa’s role as our second home outside of India was emphasised last year when Mahindra unveiled its new global Pik Up concept in South Africa to a global audience. Mahindra South Africa and its assembly facility will become an important part of the global Pik Up plans, especially with the announcement that Mahindra will continue to produce the current range of bakkies alongside the new model,” says Rajesh.

ROTARY HAMMER DRILLS ARE ESSENTIAL KIT FOR CONTRACTORS
Few tools are as indispensable as the rotary hammer drill on construction sites where the drill’s ability to deliver high-impact drilling in tough materials like concrete, brick and stone are indispensable.
They are essential for builders who need to bore precise holes or undertake heavy-duty demolition work. Unlike standard hammer drills, rotary hammers utilise a piston-driven mechanism that delivers more force per impact and making them ideal for more demanding applications in the concrete and construction industry.
Rotary hammer drills operate using an electro-pneumatic system, where an electric motor drives a piston that compresses air to create a hammering motion. This design allows for greater impact energy, enabling the tool to break through dense materials with minimal user effort. Most rotary hammer drills feature three operational modes:
1. Drilling Mode – Functions like a standard drill, suitable for light-duty applications in wood or metal.
2. Hammer Drilling Mode – Combines rotation with percussive force, making it ideal for drilling into masonry and concrete.
3. Chiselling Mode – Disables rotation and uses only the hammering action, effectively turning the tool into a mini jackhammer for demolition work.
Modern rotary hammer drills are packed with features that improve efficiency and safety. Some of the most notable include:
• SDS (Slotted Drive System) Compatibility – Most rotary hammers use SDS-Plus or SDS-Max shanks, allowing for better bit retention and quick bit changes without a chuck key.
• Variable Speed and Impact Control
– Enables precision in different applications, from delicate surface work to heavy-duty drilling.
• Dust Extraction Systems – Improve worksite cleanliness and safety by reducing airborne silica dust, a common health hazard in construction.
Rotary hammer drills have a broad range of applications in the construction industry. Their ability to drill and chisel through concrete and masonry makes them invaluable for various tasks such as:
1. Anchor Installation
Rotary hammer drills are commonly used to create anchor points in concrete for securing heavy-duty fasteners, such as expansion bolts, threaded rods and rebar dowels. These anchors are essential for constructing steel structures, installing machinery and setting up railings and fixtures.
2. Demolition and Chiselling
Thanks to the chiselling mode, rotary hammers can be used for light to medium demolition work, such as removing old tile, breaking up concrete slabs or cutting channels for electrical conduits. This function-
ality makes them a versatile alternative to larger jackhammers for smaller demolition projects.
3. Drilling Holes for Plumbing and Electrical Installations
Plumbers and electricians frequently rely on rotary hammers to drill holes through concrete walls and floors for running pipes and conduit systems. Their efficiency in penetrating dense materials significantly reduces labour time and effort.
4. Concrete Formwork and Rebar Doweling
Before pouring new concrete slabs or extending existing structures, contractors may use rotary hammers to drill holes for rebar doweling. This reinforcement technique enhances the strength and stability of concrete joints and prevents structural failure.
5. Masonry and Brickwork
Masons and builders use rotary hammers to create openings in brick and block walls for doors, windows and ventilation systems. These drills ensure clean, precise cuts that facilitate seamless installations.
6. Road and Bridge Construction
Infrastructure projects, such as road and bridge construction, require drilling into concrete and asphalt for anchoring structural components. Rotary hammers are essential for these large-scale applications, ensuring durability and precision in construction.
Selecting the right rotary hammer drill de-
pends on the nature of the job. Key considerations usually relate to power rating, which is measured in joules, impact energy determines the tool’s effectiveness in breaking through tough materials.
The drill type is important whether it is for SDS-Plus models that are suitable for stan-
dard construction work or SDS-Max models provide more power for heavy-duty applications. The weight and ergonomics also play a role. A lighter tool reduces user fatigue for prolonged use, while a well-balanced design enhances control and comfort.
