Digging tunnels is a specialist activity, involving major works that are often complex and take a great deal of time.

 

Tunnels require specific methods and equipment, plus in-depth knowledge of geotechnics. Through its specialised subsidiaries, Bessac and Soletanche Bachy Tunnels, Soletanche Bachy can take care of the entire chain of creation and remediation for underground infrastructure. In terms of design-build, our offer comprises:

• Excavation carried out by a tunnel boring machine (TBM) or using traditional methods
• Tunnel lining
• Specialist related works

To adapt to the needs of each project, we design and build our own TBMs.
