geotextile
Geotextiles are permeable nonwoven fabrics used to
separate,filter,reinforce, protect or drain.Geotextiles allow filtration or separation of granular
layers in roads and rail applications,used to protect membranes in landfill applications,used in
coastal defence applications and used in landscaping to protect surfaces and structures from weeds
and root growth.
Geotextiles are availabel as woven and non-woven .As liner protection, against physical damage, the
non wovens are normally the answer.They are made up of fibers of polyester or polypropylene in
random directions and punched together by needles during the manufacturing process.Geotextiles are
commenly used to separate layers like clay and drainage and to protect liner from damage.

Product Content
Polyester Filament Needle Punched Geotextile was made from virgin polyester chips, the continous
filament was extruded from polyester chip by machine directly by spunbond process. Pet Long Fiber Nonwoven
Geotextile punch together to get the stable 3D with highter strength fabric . so Nonwoven Geotextile Fiber
has high strength , good creep property excellent and erosion resistance, aging-resistance and heat
resistance
Performance：
Anti-aging, the
product has very high anti-ultraviolet radiation ability, not easy to degradation.
High temperature resistance to up to 230℃ maintaining structure stability and original physical
properties.
High flat drainage and vertical permeability.
High creep resistance.
Resistance of erosion of chemicals in soil as well as the corrosion of gasoline and diesel etc.
High elongation under certain stress, thus able to adapt to uneven and irregular bases.
Application:
1. Road stabilization applications
2. Roofs
3. Civil applications
4. Railway work
5. Landfill lining
6. Trenches
7. Dams
8. Fitration under rip rap and rocks
9. Environmental applications
