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.
