Tunnel: Below water level

    Tunnel: Below water level

    The use PVC-P geomembranes as a waterproofing for tunnels under water pressure is a sophisticated and safe technology to protect the construction against destructive influences of the water.

    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. 


    Together with our technical departement you will find the right technical solution for your project.

    RENOLIT offers a full range of membranes and accessories adapted to your specific tunnel project.
    They are corresponding to the most important standards as:

    • DS 853, ZTV Tunnel - Germany
    • Heft 365, RVS 8T - Austria
    • SIA 280 - Switzerland
    • Avis Technique - France

    Ask for the agreements you need to our technical department.
