Our Testing Services
Geosynthetic testing is designed to produce tensile property data for the control and specification of planar products made from polymeric materials. These materials are used with soil, rock, earth, or other geotechnical engineering materials as an integral part of man-made projects, structures, or systems. Testing ensures material performance meets project requirements and engineering standards.
Hydraulic conductivity measures the ability of a material to transmit fluid through pore spaces and fractures under an applied hydraulic gradient. Using Darcy's Law, we determine the ratio of the average velocity of fluid through a cross-sectional area to the applied hydraulic gradient. This test is critical for drainage, containment, and environmental engineering projects.
Direct shear testing is performed in the laboratory or field to measure the shear strength properties of soil or rock. It evaluates the resistance of materials or discontinuities within soil and rock masses. The methodology covers the determination of the consolidated drained shear strength of a soil sample under controlled conditions, helping engineers design safe and stable structures.
