Soil, gravel, and aggregate testing services

We provide the full range of soil, gravel, and aggregate tests required for civil engineering projects.

Our services cover everything from basic sieve analysis and Atterberg limits to advanced testing such as DMI, Venter Test, and resistivity measurements.

For stabilization design and control, we test materials for both cementitious and bituminous applications. Our experienced staff ensures all results are accurate, reliable, and SANAS-accredited, supporting the successful completion of your project.

  • Sieve analysis to 0.075mm
