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.

The clear PVC is recommmended for transparent waterproof membranes or geomembranes. PVC clear is available up to 2200mm width for large tunnels and galleries. The very high transparency is allowing to see behind the membrane until shrouding.
