Installing the cofferdam perpendicular to the watercourse | Steep slope

This is the fastest and most dramatic type of installation. The flexible cofferdams become pressurised instantly.

WaterGate is suitable for any kind of river bed: because of their incredible flexibility, our inflatable cofferdams snugly fit the banks and the bed of the waterway, whatever the terrain.

WaterGate guarantees an excellent seal thanks to the pressure exerted on the ground sheet by the water.
