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 draws on its knowledge of geotechnics and civil engineering for the design-and-build of oil and gas installations.


We operate in some of the world’s most inhospitable regions to build gas treatment plants and to create maritime infrastructure such as unloading sites and storage areas. Our expertise in port infrastructure and ground improvement means we can guarantee the longevity of our clients’ structure.
