Non woven geotextile is made from virgin continuous polyester filament by needle punching and thermally bonding process to formstrong fabric that retains its dimensional stability and is resistant to damage from construction stresses. BPM polyester filament non woven geotextile offers optimum performance per unit weight which features high tensile strength and puncture resistance, goodacid and alkali resistance, excellent drainage and anti-aging properties, etc. Polyester filament non woven geotextile is widely used for separation, filtration, drainage, protection and reinforcement functions in civil environmental engineering and construction projects.
