A project manager requires precise information about the subsoil. That is a basic requirement, both for the design of a construction project and for carrying out environmental inspections. Not only he has to know the characteristics of the subsoil, he also has to be sure of the precision of the results on which he can base himself. Besides state-of-the-art equipment for carrying out soil tests, Geosonda also disposes over long-term experience and extensive expertise in this area. This combination makes it possible to propose an excellent solution, for almost every structural or environmental-technical issue.
