And in contaminated environments


Since 1988, we have specialized in subaquatic operations in polluted, contaminated, and hostile environments. Based in Saint-Coulomb, Brittany, we operate from Nantes to Bordeaux, from Rennes to Toulouse, and throughout France. Our divers (class II, mention A) guarantee meticulous work, in compliance with safety standards.

The subaquatic operations carried out in polluted environments mainly concern the maintenance of wastewater treatment plants and biogas plants. The lack of visibility and the challenges of diving in such environments require specific know-how and expertise, which our teams of specialized divers provide. We also operate on lift stations and anaerobic basins.
