In the tunnelling field, Soletanche Bachy’s subsidiaries Soletanche Bachy Tunnels and CSM Bessac specialise in management of tunnel sites and also, for the latter, the design and construction of tunnel boring machines.

In addition, mastery of the associated techniques (drilling, grouting, ground water control diaphragm walls, anchorings, etc.) allows the Group to undertake complete projects. Soletanche Bachy also undertakes maintenance of tunnels, for example, through its subsidiary Sotem, which maintains the Paris Metro tunnels.
