Protection of the environment

Soletanche Bachy, and its subsidiary Solenvironment, provide solutions for pollution issues, involving, for example: inertisation of waste, rehabilitation and treatment of polluted sites, cleaning of discharge to required environmental control levels, construction of waste storage facilities, protection of groundwater.

Developing individual solutions for such sites requires that regulations, physical and chemical conditions, and the hydraulic and geotechnical characteristics of each site are taken into account.

Other Group companies provide support, on a project by project basis, in constructing, for example, cut off walls for containment of polluted water or reactive barriers.
