Triaxial testing is the most comprehensive method for determining the shear strength parameters of soil. It provides the cohesion and friction angle data that geotechnical engineers rely on for slope stability analysis, bearing capacity assessment, retaining wall design, and foundation engineering. Western Geotechnical Laboratory Services (WGLS) provides a full suite of accredited soil triaxial testing to AS 1289.6.4.2, covering all three standard test types in both single stage and multi stage configurations. Unconsolidated Undrained (UU) testing provides rapid shear strength data for soft cohesive soils where drainage is not permitted. Consolidated Drained (CD) testing measures the effective strength parameters of soils under slow, drained loading conditions. Consolidated Undrained (CU) testing determines effective strength parameters with pore pressure measurement, suited to soils where loading occurs faster than drainage allows. All six test configurations are available from our NATA-accredited laboratory in Welshpool, Perth.
