GeoSonic’s Sonic rigs can offer continuous soil samples (presented in either flexible plastic liner bag or semi-rigid plastic liners) recovered by means of Sonic Drilling.
A full range of geotechnical samples can also be recovered by means of dedicated geotechnical samplers utilising the same rig but without the use of resonance. These include thin walled samplers, piston samplers etc. which meet the requirements of current Eurocode standards.
Full details of our capabilities are listed in the Services & Experience section.
