Product Description
China Manufacture PP White/Black Color Long Fiber Filament Needle Punched Non-Woven Polypropylene Geotextile for Sand Filtration
Geotextiles are innovative, permeable materials made from synthetic fibers, primarily used in civil engineering and construction to enhance soil stability and drainage.
Composition
- Raw Materials:
- Polyester (PET)
- Polypropylene (PP)
Types of Geotextiles
Woven Geotextiles:
- Created by weaving fibers together.
- Known for high tensile strength, making them suitable for heavy-duty applications.
Non-Woven Geotextiles:
- Formed by bonding fibers through various processes.
- Ideal for filtration, drainage, and separation tasks.
Key Applications
- Soil Stabilization: Helps in reinforcing weak soils.
- Erosion Control: Prevents soil erosion in various environments.
- Drainage Solutions: Facilitates water movement through soil layers.
- Road Construction: Enhances the durability and lifespan of roads.

Geotextile Production Process
APPLICATION
Major functions: Separation, filtration, drainage, reinforcement, protection, and liquid barrier
1) Filtration 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) 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)Adding muscle 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 earth body stability.
4)Protection It prevents the bank from being washed out, protects the bank and the bottom, prevents the water and soil from being washed away.
