Waterproofing of tunnels
In the tunnel waterproofing covering the outside of the tunnel, materials that provide a high classification of reaction to fire and high mechanical characteristics are required, as well as the proper functions of guiding-channeling the tunnel water leaks from the vault to the gable end. TROCELLEN TUNEL CLASIFICADO FUEGO is a composite and lightweight plastic sheet which offers such functionalities.
Waterproofing sheet composed of:
- Technical reinforcing fabric that provides the sheet with a high resistance to breakage and a good tear behavior to the nail.
- Chemically cross-linked polyethylene foam with low water absorption and a low coefficient of thermal conductivity that provide the sheet with thermal insulation properties, preventing leaks
- Polyethylene film, which facilitates the work of installation favoring the sticking / heat welding of the overlaps between sheets.
