Specifications of Geotextile
Needle-Punched Non-Woven Geotextile is a special kind of nonwoven geotextile because of its special manufacture method by puncturing the rolling formed layer made of randomly oriented short staple fiber. Our raw material is the top class 100% new PP(Polyproplylene ) or PET(Polyester) fiber. The needle punch process involves forcibly entangling layers of loose staple fibre into three dimensional structure by sequentially punching and pulling out barbed needles through the fiber matrix, and forms a strong fabric that retains its dimensional stability, expands the serving year to all the applied project. Because of its proven track record and versatility, Needle Punched, as the most commonly used Nonwoven Geotextile, is widely used in civil and environmental engineering applications like subsurface drainage, roadway separation, railroad stabilization, erosion control, hard armor underlayment, landfill leachate collection, underground retention/detention systems, environmental protection and other projects.
Application of Geotextile
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.
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.
The highway, railway, soilstone 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.
It prevents the bank from being washed out, protects the bank and the bottom, prevents the water and soil from being washed away.
Woven geotextile :
Made from polypropylene and or polyester fibers, manufactured with high tensile strength and low elongation, our woven geotextiles have superior properties for filtration, separation, reinforcement, erosion control and drainage. We are leader in providing woven geotextiles for a variety of civil and environmental applications including highways, port facilities, reservoir, transport construction, waste and chemical management ,subgrade engineering, coast reclamation works, peninsula shoal engineering.
