“Our role is to ensure consistent, verifiable quality from source to site. By embedding testing within the production process, we’re improving control, reliability, and traceability before a single load leaves the factory.” 

This initiative follows Roadlab’s initial visit in August, when site layout, equipment selection, and accreditation planning began. Once complete, the Mtwara facility will perform physical and chemical testing under ISO/IEC 17025 standards, strengthening quality assurance throughout Dangote’s cement supply chain.

Mastersizer 3000E Validation Study

At the T&M Conference, Group Quality Manager Janco Potgieter presented Roadlab’s multi-laboratory study
comparing traditional hydrometer particle size analysis with next-generation laser diffraction using the Malvern
Mastersizer 3000E.

“We’re not replacing the science — we’re refining it,” Potgieter noted. “Our goal is to ensure every result we issue,
no matter the method, reflects the same level of trust and traceability.”

The study — performed across three laboratories following SANS 3001, ASTM D422, and BS 1377 standards —
demonstrated that the Mastersizer delivers faster, more repeatable, and more operator-independent results
than the hydrometer method.

Our presentation concluded that laser diffraction is fit for purpose in soil testing — particularly when supported
by robust quality controls under ISO/IEC 17025 — and that it represents a forward step toward harmonising particle size standards for the next generation of testing.

Roadlab Mauritius seeks MAURITAS accreditation.

Roadlab Mauritius is on the verge of a major milestone. Once approved, the laboratory will become only the second privately accredited facility in the country, with the broadest scope of testing services nationwide.

Launched in 2022, Roadlab Mauritius extends the group’s reach to 22 African countries.

The laboratory has been instrumental in providing independent quality assurance for both government and private sector projects on the island over the last 3 years. Through close collaboration with local engineers and contractors, Roadlab has raised the benchmark for testing accuracy and traceability in the region.

With a MAURITAS accreditation now in process, the Mauritius laboratory is set to serve as a regional reference point — connecting local projects to continental expertise, and ensuring that the same standards trusted across South Africa are applied in Mauritius.

Building A Living Quality Management System

Potgieter is also presenting at the SAQI National Quality Conference this month, sharing insights into how Roadlab’s integrated Quality Management System (QMS) anticipates risk and reduces non-conformances across its national network of more than 60 accredited laboratories. 

“Quality is not a department — it’s a shared responsibility,” Potgieter explained.
“Our system lives through the people who apply it every day, and that’s what keeps our results reliable.”

His presentation, “Building a Living QMS that Anticipates Risk and Reduces Non-Conformances,” will explore how Roadlab’s QMS acts as a living system — continuously adapting through data-driven feedback, proactive training, and real-time process control.

Rather than existing as static documentation, Roadlab’s QMS connects technicians, quality officers, and managers through constant feedback loops. The result is early identification of risk, improved consistency, and greater confidence in every result delivered.

You will find us at the forefront of quality assurance. Why?

Every presentation, every audit, and every new laboratory we establish has a single purpose — to strengthen confidence in  results.

By embedding testing at the source, refining analytical methods, and continuously improving how our systems perform, Roadlab is advancing the standards that define quality assurance in our world.

Because our standards are the future of testing.
