Thanks to our R&D, design, and engineering capabilities, we have developed new foundations processes, soil technologies and bespoke machines to ensure the success of construction projects with major geotechnical components.
Turning the challenges our clients face into solutions is what we do best.
With Soletanche Bachy, you can count on the world’s biggest network of engineers specialising in geotechnical structures, who form the bedrock of our advanced techniques in this field. Our teams are on hand to assist with all aspects of our clients’ projects, from deciding on the best methods to deploy, through design, dimension calculation, planning, and equipment supply.
We offer the widest range of geotechnical solutions on the market: deep foundations (piles, micropiles), retaining structures (diaphragm walls), reinforcing (freezing, underpinning), cut-off solutions (grouting, Deep Soil Mixing), civil engineering, ground improvement, and tunnels.
This cutting-edge expertise in foundations and soil technologies, in conjunction with our in-house design offices, allows us to propose variants right from the design phase, whenever possible.
To date, Soletanche Bachy has received 60 innovation awards internationally, including 22 from the French Federation of Public Works.
