AGRUFlex®

Product Overview

AGRU America’s AGRUFlex® Tunnel Liner protects concrete tunnel structures against the infiltration of water, aggressive soils, and root penetration. This tunnel lining system offers superior water resistance, reducing the maintenance costs of having to repair water spots, dripstones from lime diffusion, and external corrosion.

The co-extruded VLDPE tunnel liner is produced by flat die calendering. The liner has a black base layer and a white or brightly colored signal layer. VLDPE’s excellent flexibility guarantees a perfect fit to the tunnel structure as well as easy installation, resistance to aggressive groundwater, and leak-proof joints between the polyolefin tunnel liners.

Technical Aspects

AGRUFlex is created from high-grade resins of quality raw material. The manufacturing process yields a highly flexible tunnel lining material that is easy to install and weld. No toxic fumes are produced should AGRUFlex come into contact with a chemical or electrical fire. And its high-quality construction and EasyFix system ensures maximum service life.
