GeoTesting Express performs a full-range of tests on rock. We prepare and tests rock specimens in-house. Servicing the geotechnical, tunneling, mining and excavation industries, we provide rapid strength and index testing of rock samples. We can prepare test specimens from cobbles, boulders, blocks or cores with our equipment. We can also core specimens perpendicular to the direction of a core run.

We utilize specialized equipment and have developed detailed processes for preparing specimens to meet the specifications set forth in ASTM D4543: "Preparing Rock Core Specimens and Determining Dimensional & Shape Tolerances", which is a requirement for any rock strength test. GTX is validated by the U.S. Army Corps of Engineers and accredited by A2LA for testing rock samples.

Rock requiring unconfined compression or triaxial compression testing must be prepared and meet very strict dimensional tolerances in accordance with ASTM D4543. Our technicians can prepare up to 8 rock specimens at one time with a higher degree of precision using our Okamoto surface grinder.

GTX is one of the few labs in the world that strictly adheres to the ASTM requirements for dimensional tolerances. Tests performed without well prepared surfaces will give much lower unconfined compressive strength which can mislead one to choose the wrong mining equipment.

GeoTesting Express utilizes state-of-the-art automated testing equipment to perform high-end strength testing of rock (Unconfined Compression, Direct Shear, Brazilian Tensile Strength, Elastic Moduli, Triaxial, etc.).
