Independent, South Australian owned and operated
In-situ geotechnical testing
CPT South Australia provides cone penetration testing (CPT/CPTu), flat dilatometer testing (DMT) and downhole seismic testing throughout South Australia and interstate.

Testing capabilities
CPT / CPTu
Digital cone penetration testing with tip resistance, sleeve friction, pore pressure and inclination measurements. Pore pressure dissipation testing as required.
Flat dilatometer (DMT)
Marchetti flat dilatometer testing for in-situ soil characterisation.
Seismic testing
Downhole S-wave measurements. P-wave acquisition available where appropriate to the investigation.
Equipment
Geomil digital CPT system with 10 cm² compression and subtraction cones. Digital signal processing and RS485 communications are well suited to electrically noisy environments.
| Tip resistance (qc) | Up to 100 MPa |
| Sleeve friction (fs) | 2–6 MPa |
| Pore pressure (u2) | Up to 5 MPa |
| Inclination | Up to 20° |
CPT truck
Mercedes 6×4 CPT truck with a dedicated three-cylinder diesel hydraulic power pack and two-speed push/pull system.
| Push capacity | 20 tonnes |
| Pull-out capacity | 30 tonnes |
| Reaction mass | 19 tonnes |
Standards and deliverables
CPT testing to AS 1289.6.5.1 and with reference to ISO 22476-1. DMT testing to ISO 22476-11. Downhole seismic testing with reference to ASTM D7400/D7400M.
Typical CPT deliverables include formatted sounding traces in PDF and data in Excel format.
Qualifications and compliance
Operated by a qualified geologist holding a National Class 2 Water Well Drillers Licence, with endorsements for auger, rotary air, mud and non-drilling operations.
Safe work method statements, pre-start checks and plant maintenance records are maintained. Public liability and professional indemnity insurance held.
Permit requirements depend on the proposed work. Contact the relevant South Australian regulator for current requirements.
