Geotextiles as permeable textile materials used in contact with soil, rock, earth or any other geotechnical related material as an integral part of civil engineering project, structure, or system. Textiles play a significant role in building infrastructures, offering desirable properties such as lightweight, strength, and resilience as well as resistance to many factors such as creep, degradation from chemicals, sunlight, and pollutants.
Geotextiles are made from polypropylene, polyester, polyethylene, polyamide (nylon), polyvinylidene chloride, and fiberglass. Polypropylene and polyester are the most used. Sewing thread for geotextiles is made from KevlarL or any of the above polymers.
