Geotextiles are widely used for filtration in road works and railway constructions as well as coastal protection.
In the EN ISO standards, the filtration function is defined as "The restraining of soil or other particles subjected to hydrodynamic forces while allowing the passage of fluids into or across a geotextile".
The characteristic opening size of Fibertex Geotextiles is designed to retain particles while allowing free movement of water, making it possible to separate two layers during intense hydraulic activity. Migration of layers, which would reduce the load-bearing capacity of the construction, is thereby avoided and, at the same time, water flow is maintained with minimum pressure loss. The tensile strength, puncture resistance and elongation properties of the geotextile have to be sufficient not only to fulfil the requirements of a filtrator but also to resist damage during installation.
