To be able to create accurate samples during geotechnical investigations we offer several types of casings.
The casings are drilled down through fill material to be able to drive down a clean pipe, for instance a sampler.
The pipe can be used for metering the water table,
hydrological testing, measuring pore pressure, of for sampling. Our Mitsubishi, ring system is adapted to ream a piston
sampler, type St ll.
The system consists of a pilot bit, ring set and a casing. It is easier to drill down than the OD-system, since the casing doesn´t rotate during drilling.
