MEMBRANE PROTECTION & DRAINAGE
Geotess® geotextiles are widely used for protection in waste disposal systems and tunnel constructions to ensure the integrity of a sealing material (for example geomembrane) when fill material and/or loads are applied.
The protection function is defined as "The prevention or limiting of local damage to a given element or material by the use of a geotextile". As the sole purpose of this function is to protect a given element or material, the mechanical properties are essential, whereas the hydraulic properties are of less importance. The excellent static puncture resistance of Geotess geotextiles makes them ideal for protecting waterproof membranes and other sealing materials from puncture when fill material and/or loads are being applied. When placed between sealing material and other layers, the Geotess geotextiles withstand and distribute any local pressure from the layer above, ensuring that the protected material is not stressed to failure protection.
Geotess® geotextiles on both sides of membranes in waste disposal protect it from perforation. Geotess protect impermeable membranes of landfill basal areas, side walls and caps, tailing lagoons, reservoirs, balancing ponds, reed beds and artificial lakes.
Geotess® geotextiles on both sides of membranes in tunnel construction and protect it from perforation. Coatings and membranes applied to concrete structures are often in need of protection.
