Waterproofing of Tunnels against infiltrating Water
The use PVC-P geomembranes as a waterproofing for tunnels under infiltrating water is a sophisticated and safe technology to protect the construction against destructive influences of the water.
Excavated tunnels belong to the most expensive and complex constructions of civil engineering. Therefore the interest to keep them working over many decades is a crucial question. Waterproofing of tunnels made it possible to increase the time of use in an important way. Many different materials were tested and used as waterproofing for tunnels and PVC-P geomembranes have proved to be the most reliable and technically suitable material of all. Depending on the local condition the PVC-P geomembrane can be formulated to meet exactly the demands of the project.
The project of Ferden – belonging to the tunnels chain for the new Gotthard Tunnel - shows that RENOLIT is able to adapt the geomembrane to such local conditions as micro-organisms and high mountain pressures.
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.
