Investigations

Geotechnical investigations are one of the key stages of soil investigations that are carried out between the geotechnical feasibility study and the final construction of structures.
Depending on the results, the investigative teams can proceed to:
- core boring down to a depth of more than 100 metres, in all types of soil and also via sanitation facilities and water tunnels;
- core boring to take soil samples to determine the mechanical quality of the ground;
- pressure measurements to determine the ground’s modulus of elasticity;
- destructive drilling to check soil characteristics and confirm the cross section of the ground;
- permeability and pumping tests.

Geotechnical investigations particularly serve to determine:
- the level and type of foundations best suited to the project;
- any geological issues on the investigated site.
