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 industrial buildings and warehouses.


These structures must respect strict constraints in terms of levelness and load-bearing capacity. That is why we put our knowledge of soils and geotechnical solutions in the service of our clients to build specially adapted, high-performance foundations. Earlier in the process, our teams can carry out ground improvement and depollution works.
