Our CPT rigs are able to retrieve soil samples utilising a variety of equipment.
Ranger 66 - available on all CPT rigs
This soil sampler provides a 66 mm diameter undisturbed sample suitable for triaxial or oedometer testing.
The sample length is 0.55 m.
It is a piston sampler.
Soil samples can be retrieved in steel or plastic tubes.
Soil samples can be retrieved quickly with the CPT trucks.
VERTEK - available on all CPT rigs
This soil sampler provides a 35 mm diameter undisturbed sample.
It can sample over a 0.5 m length but it is modular so can be extended.
It is a piston sampler.
Soil samples can be retrieved in split tubes or plastic tubes.
Soil samples can be retrieved quickly with the CPT trucks.
MACRO and DT22 - available on Geoprobes
This soil sampler provides a 35 mm diameter undisturbed sample.
It can sample over a 1.5 m length but it is modular so can be extended.
It is hammered into the ground with the Geoprobe.
Soil samples are retrieved in plastic tubes.
Soil samples can be retrieved quickly with the Geoprobe.
The DT22 has casing and is more efficient below a depth of 5 m.
