The geombrane protects the tunnel against the underground water. With the development of the new high speed railway tracks, tunnels became longer and the challenge for the waterproofing system became higher. Many of these tunnels are exposed to high water pressure. It is important to use high quality geomembranes in thickness superior to 2,0 mm to reach a higher puncturing resistance. In order to restrain an ingress of water through the membrane, compartments composed with water stop profiles and injection hoses, need to be installed into the waterproofing system.
The RENOLIT Group has the right product to make your tunnel watertight against the underground water.
