Production introduction:
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.


Geotextiles can be used as:
* Filtration or separation layers in civil engineering projects of roads and railway construction;
* Protect layer for geomembranes in landfill construction;
* Coastal defence applications
*  Landscaping projects to maintain soil and protect land surfaces and structures from weeds and root growth.
