Major functions of nonwoven geotextile: Separation, filtration, drainage, reinforcement, protection, and liquid barrier. The geotextile can also be heat treated by infrared at customer's requirements. Our geotextile are UV stabilized to give protection against aging under exposure to natural ultra-violet light.
