The geotechnical study makes it possible to take into account the nature of the formations by constituting the subsoil of the site where it is planned to carry out a development.
This study makes it possible to adapt the project (building, bridge, road, etc...) to the envisaged site, to define the system of formation of the work with the best safety/cost ratio.
A serious geotechnical study contributes to the success and durability of a structure.
The Works Department is made up of a team, 3
engineers, 2 senior technicians, 4 sounders, as well as highly qualified and experienced sounding and manoeuvring assistants, and a fleet of vehicles and machinery made up of the following main means :
In addition, the Works Department has a wide range of equipment and test materials that enable it to carry out a wide range of investigations, both on the surface and at depth.
Surveys by shovel ;
Destructive probing by rotation and roto-percussion with parameter recording;
Traditional and cable core drilling ;
