Investigations, surveys and tests for geotechnical, geomechanical and hydrogeological characterization of in-situ rocks and soil.
Assessment of physico-mechanical properties and natural stress state
- large size sampling of rock and soil
- sampling of cylinders through die-cutting and coring
- density and water content tests of soil (*)
- load tests on plate on soil (*)
- load tests on plate on rocks
- large scale tests of compression, shear and swelling
- pressiometric and dilatometric borehole tests
- single and double flatjack plate tests
- overcoring 2D (Doorstopper) and 3D (CSIR, CSIRO) and undercoring tests
