AgruFlex® Tunnel Liner
Whether used in blast and bored or conventional tunnel constructions, AgruFlex® Tunnel Liner protects concrete tunnel structures against the infiltration of water, aggressive soils and root penetration.
A very low density polyethylene (VLDPE), AgruFlex® Tunnel Liner combines flexibility with tensile properties, chemical resistance and long-term performance.
Due to its superior water resistance, AgruFlex® reduces the maintenance work needed to repair water spots, dripstones from lime diffusion and external concrete corrosion.
Because VDLPE contains no volatile plastizicers, the AgruFlex® keeps its mechanical properties – ensuring tight construction for the life of the tunnel. AgruFlex® is easy to install with good weldability. It emits zero toxic fumes in case of fire.
AgruFlex® combines a black base layer with a bright signal layer and can be used with Geotexile, HDPE or LLDPE liners for cut and cover tunnel constructions.
