Non woven geotextile filter fabric 8 oz is one of the strongest and most common medium weight nonwoven geotextiles. With a grab tensile strength of 205 pounds, 8 oz non woven geotextile filter fabric can provide sediment control on hillsides and riverbanks. Since it has a high flow through rate and is pliable fabric, 8 oz. geotextile fabric has become a standard geotextile filter fabric for French drain systems. Made of polypropylene with a needle punched process, the fabric is strong, permeable and pliable. Non woven geotextile filter fabric is also available in lightweight or heavyweight models, for flexibility in selecting the best fabric for each project's specifications.
