1.Product Description
Needle punched nonwoven Geotextiles are made of polyester or polypropylene in random directions and punched together by needles Geotextiles has good impermeability and resistance to deformation, which allows geotextiles be widely applied in civil projects for separation,filtration,reinforcement, protection and drainage.
2.Product Feature
* Good water permeability
* Anti-corrosion
* Anti-aging
* Wide range of adaptation
* Low creep
* Resistance to external damage
