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.
In the EN ISO standards, 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 Fibertex 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 Fibertex Geotextiles withstand and distribute any local pressure
from the layer above, ensuring that the protected material is not stressed to failure.
