The 12 oz. nonwoven geotextile drainage fabric is a heavy weight geotextile used for filtering, underlayment, sediment control, and stabilization. The 12 oz. geotextile offers a grab tensile strength of 300 pounds and still maintains a 50% elongation ability. The 12 oz. nonwoven fabric offers a high resistance to UV exposure, rotting, and other chemicals by being constructed from polypropylene. The polypropylene fibers are put together by a needle punching process to create the nonwoven geotextile. The process helps the material maintain great flexibility and filter out sediment in areas as needed.
