Soil

Western Geotechnical & Laboratory Services are simply the best construction material testing laboratory in Western Australia. No one can compete with our unwavering delivery of excellence, backed up with our continual and consistent on-time delivery of results.

Our Laboratory construction materials testing scope of general classification, strength and compaction testing in accordance to AS 1289, MRWA, ASTM and many more standards includes but isn’t limited to:

Laboratory Permeability Testing – Falling Head, Constant Head and Flexible Wall Permeability
Dispersion Testing – Emerson, Pinhole, Percent Dispersion
Playing Field Assessment – USGA Particle Size, Porosity, Hydraulic Conductivity, Water Holding Capacity and Moisture Release Curve.
Compaction and CBR Testing (Laboratory holds over 100 mould’s for efficient completion of large projects)
Classification Testing including Particle Size Analysis, Hydrometer, Shrink Swell Index and Atterberg Limits
Organic Testing both Chemical and Loss On Ignition
Thermal and Electrical Conductivity / Resistivity
