Geotextiles are widely used for drainage in earth and construction works.
In the EN ISO standards, the drainage function is defined as "The collecting and transporting of precipitation, ground water and/or other fluids in the plane of the geotextile".
Hydraulic properties are decisive for the overall performance of the entire construction, with the water flow capacity in the plane of the geotextile being the most important.
The hydraulic properties of Fibertex Geotextiles are designed to drain excess water off the construction - not by passing through the Fibertex Geotextile as when used for filtration, but by flowing in the plane of the geotextile leading it away from the construction. The use of a drainage geotextile ensures ongoing drainage of fluids with minimum pressure loss.
