Woven geotextiles are made from polypropylene or polyester yarns that are woven into a fabric. They are strong, durable, and have high tensile strength. They are used for reinforcement and separation applications.A woven geotextile has a very uniform pore size which varies under load making them less suitable for filtering anything other than clean single sized soils/fills.
Non woven geotextiles are made from polypropylene or polyester fibers that are randomly laid and then bonded together by needle punching, thermal bonding, or chemical bonding. They are less strong than woven geotextiles, but are more permeable and are used for filtration and drainage applications.
