Tunnel: Excavated

    Tunnel: Excavated

    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.

    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 and it has to be sure that the waterproofing system is adapted to such strain.

    It is important to use high quality geomembranes in thickness superior to 2,0mm as the puncturing resistance of the geomembrane rises exponential with increasing thickness. Also the bottom of the tunnel is receiving a complete waterproofing. The whole waterproofing system has to be adapted as it is not excluded that the geomembrane will not be punctured during the construction work. Therefore compartments with water stops and injection hoses minimize repair costs in case of a damage of the waterproofing 

     

    The RENOLIT Group has the right product to make your project watertight against the negative influences of water. The technical service is also available to you in finding the right technical solution for your waterproofing task. This combination should help you to offer a satisfying work to your client.

    To have more detailed information about how to execute the waterproofing of tunnels under water pressure, see the document about “Waterproofing of Tunnels under water pressure”.

    Depending on the application, RENOLIT can offer the right membrane for the right purpose
