Geotextiles form one of the two largest group of geosynthetics with their use growing significantly over the years. They are textiles made of synthetics which may be woven, non woven or knitted and are totally biodegradable. The flexible porous quality allows water to flow across their manufactured plane and also within their place to widely varying degrees.

Geotextile is used in civil engineering, coastal engineering and construction sites. Generally, GeoTextiles are located in the tension area to make the soil stronger.
