Geotextiles are permeable fabrics which, when used in association with soil, have the ability to separate, filter, reinforce, protect, or drain. Typically made from polypropylene or polyester, geotextile fabrics come in three basic forms: woven, needle punched or heat bonded.  Geotextile composites have been introduced and products such as geogrids and meshes have been developed.   DuPont’s patented production technique is one of the main reasons for the unique properties of Typar® compared to other geotextiles. Overall, these materials are referred to as geosynthetics and each configuration—-geonets, geogrids and others—-can yield benefits in geotechnical and environmental engineering design.
