Waterproof membranes

Galleries and tunnels

In underground works, geo-membranes have an essential function in preventing the infiltration of water and providing protection of the structure. They are an effective solution for waterproofing and sealing work.

The use in particular of a transparent PVC membrane, not only translucent, easily ensures an effective and safe weld between the strips.

Extruflex membranes are available from 1 to 12mm thick and up to 2.2m wide.
