geotextile can be made of polypropylene (PP), or polyester (PET), Polyvinyl or synthetic fiber on needle punch machine.
Application
Filament nonwoven geotextiles have a wide range of applications in civil environmental engineering and construction projects. Their uses include:
- Filtration of soils in drainage applications by retaining soil particles while allowing for the free flow of water
- Separation and stabilization in road and railway construction
- Prevention of soil movement in erosion control measures
- Cushioning and protection in many containment projects
Feature
1.Can withstand construction installation stresses
2.UV (Ultra Violet) Stabilized
3.High Chemical Resistance
4.Optimum Elongation

Long Fiber Geotextile Functions
1. Long Fiber Geotextile Filtration
It can be the filtration layer of the dykes, river canal, seacoast, concrete slope, retaining walls. At the same time of preventing the clay granule from passing, it allows the water and the gas pass through freely.
2. Long Fiber Geotextile Separation
The isolation of the railway dregs and the roadbed, roadbed and the soft base, surface of the airdrome and parking lot and the groundsill, different dam materials. It isolates the soil and the gravel of two kinds different granule pathway from the groundsill or other buildings.
3. Long Fiber Geotextile Reinforcement
The highway, railway, soil-stone dam, breakwater, airport, backfill soil of retaining wall, slope protection, etc in which distributes the earth stress, prevents the side-displacement of the earth body and improves the earthbody stability.
4. Long Fiber Geotextile Protection
It prevents the bank from being washed out, protects the bank and the

4. Long Fiber Geotextile Protection
It prevents the bank from being washed out, protects the bank and the
bottom, prevents the water and soil from being washed away.
5. Long Fiber Geotextile Anti Aging
The fabric 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.
Long Fiber Geotextile Applications
It is widely used in the areas of railway, highway, water conservancy, dam, tunnel, subway, environmental protection and so on.
