Non-woven geotextiles are manufactured by the perforation of cut fibres and can be used for protection, filtering, separation, drainage and reinforcement (see also Woven geotextiles and geogrids).
Non-woven geotextiles are one of the largest groups of geosynthetics. An important property of geotextiles is their porosity, which allows the passage of liquid, with varying levels of permeability. They are generally used for protecting geomembranes, separation, reinforcement, filtering and drainage.
