Soletanche Bachy offers foundations and geotechnical solutions for all types of structure, from the largest international infrastructure to small local projects.

Bridges, highways, rail links, tunnels, dams, mines, power stations, buildings, towers, ports: as general contractor or specialist subcontractor, we offer foundations solutions and soil technologies for the design, construction, remediation, and commissioning of our clients projects.

Soletanche Bachy is involved in the design and build of offices and housing. We also build underground car parks with several levels, notably for tower blocks.


We adapt our geotechnical and foundation solutions to the type of project, the nature of the ground, and the risks associated with geographical location of the structure, such as earthquake risk or the slope of the ground. Soletanche Bachy can also provide clients with environmental certification via the development of eco-responsible materials.
