As one of the leading CPT operators in New Zealand, we also perform Seismic Cone Penetration Testing.
The seismic CPT acquisition is conducted with a 10cm2 compression CPT (U) cone allowing both CPT data and SCPT data to be collected at the same time.
The analysis and reporting of the seismic data is interpreted in-house.
Pore pressure dissipation tests
Help with the identification of soil permeability and static groundwater levels in permeable soils
Insitu CBR and plate bearing tests
Our CPT rigs are also equipped to undertake insitu CBR and plate bearing tests.
WSP have the capabilities of soil sampling with a VERTEK Soil Sampler, this method of sampling is a reliable and cost effective method of retrieval of minimally disturbed soil samples in difficult geological conditions. It is designed to be pushed with standard CPT equipment. Our soil sampler can collect full sample tubes for geotechnical or environmental laboratory testing. It has been designed with a unique core catcher to retain loose soils that tend to flow out of standard samplers. The diameter of the soil sampler is 35mm with a length of up to 600mm.
The soil sampler may eliminate the need for drilling on many projects. More on the soil sampler.
All our cones measure pore pressure, friction and tip resistance. We continually update our software so that we have the latest technology and provide the most accurate results possible. We ensure our calibration of equipment is done regularly to meet with industry standards.
We can pre-core our holes through concrete up to a thickness of 300mm, only disturbing a small area making for an easy reinstatement.
We have a temperature cone, which in addition to all the standard measurements, can also measure temperature. This function allows us to monitor the temperature of the soil in potentially geothermal areas and continue to test safely within given limits.
