As demand grows for accurate geotechnical data in mining, tunneling, quarrying and infrastructure testing, modern rock testing is evolving to meet the needs of fast-paced, high-impact projects. Understanding how rock behaves under stress is critical to ensuring stable foundations, optimizing equipment use and enhancing safety across operations.
One emerging trend is the use of onsite labs, which enable quicker decision-making by delivering test results without the delays of sample transport. This is particularly valuable in remote or mobile projects, where efficiency is essential and access to central labs may be limited.
At SGS, our project labs support field teams with real-time data across rock, soil, aggregate and concrete testing. Backed by ISO/IEC 17025 (NATA) accreditation for over 80 methods, we ensure traceability, accuracy, and confidence in every result.
Standard tests include:
-
Uniaxial Compressive Strength (UCS) – for evaluating structural stability
-
Young’s Modulus and Poisson’s Ratio – for modeling material deformation and stress response
-
Cerchar Abrasivity Index (CAI) – evaluates abrasivity for tool wear management
-
Point Load and Brazil (indirect tensile strength) – quick strength and fracture estimation
-
Slake Durability – for assessing resistance to weathering and breakdown
-
Rock Direct Shear – used to determine cohesion and friction angle for assessing interlayer movement and slope stability
-
Tests following guidelines such as AS4133 to ensure best practice and technical rigor
We leverage a global testing network of Construction Materials Testing (CMT) laboratories, enabling consistent methods, aligned reporting formats and access to international technical expertise. This global-local approach supports complex projects with high technical standards, regardless of location.
Automated testing systems play a key role in improving efficiency and data quality. At the same time, sustainable testing practices, such as energy-efficient tools, recycling rock samples and safe chemical handling, are embedded in our operations.
As projects push into more challenging environments, we continue to refine our testing approaches, helping clients make faster, smarter and more sustainable decisions with confidence.
