Cone Penetrometer Testing

Standard cone (CPT

Qc & Fs

Piezocone (CPTu)

Qc, Fs, and Pore Pressure

Electronic hand-held Penetrometer

To measure bearing strength of tailings dams and intertidal mudflats etc to determine vehicle type for access

Onsite piezocone de-airing

De-airing system

Vacuum chambers capable of completely saturating fully assembled piezocones prior to each test.

Precision calibration

High precision field portable calibrators

High precision calibrators to maintain and calibrate the CPT Probes. This helps ensure instrumentation quality and provide a guaranteed level of accuracy.

Dilatometer Tests

Dilatometer (DMT)

Detecting slip surfaces in OC clay slopes
Monitoring compaction control
Liquification etc

Seismic Dilatometer (SDMT)

For the determination of shear velocity and shear modulus, ideal for determining liquefaction potential.

Automatic Shear Wave Generator

Automated shear wave source providing identical amplitude and frequency.

Shear Vane Testing

Shear Vane Testing equipment with electronic inline torque sensor

Available for very soft to firm clays

Soil sampling

Undistributed soil sampling

Particularly suited to mine tailings and acid sulphate soils but also most materials in an absence of gravels.

Installations

Vibrating Wire Piezometers

Tailings dams, reclamation sites, dam walls etc

Standpipes

As above

Vibracoring

Track mounted vibracore rig

Sampling ‘Potential Acid Sulphate Soils’ and mine tailings etc
