Needle-punched non woven geotextile
Needle-punched non woven geotextile with various indicators of quality, with good stress -- strain and toughness, seepage performance and uniformity, and width, etc., And is applicable to roads, water, rail, mining dams, rivers, airports and other civil engineering, anyone in the works played reinforcement, segregation, filtration, filtration, drainage, and then extend the project life, reduced cost and easy construction, and it is easy to ensure the quality of the project.


Needle-punched non woven geotextile is formed by long yarn or short fiber laid to net sharp by different equipments and technology, different fibers interwining with each other through needle punching etc technics, this would make the fabrics normalized, soft, plump, thick and stiff to meet different thickness and usage requirements. Needle-punched non woven geotextile has good fabric gap and adhesion, meanwhile it has excellent adaptive ability to deformation and plane drainage capacity because of the fiber is soft and has a certain degree of anti-breaking ability.

1.Water conservancy project dams and slope of filtration , channel isolation, impervious ;
2.Highways , railways, airport runways based isolation, filtration , drainage, slopes, retaining walls and pavement reinforcement, drainage ;
3.Port engineering soft ground , beach causeway , harbor piers and breakwaters reinforcement, drainage ;
4.Polyester filament geotextile has been widely used in the field of infrastructure construction , and gradually be applied to a wider range of fields.
1.Artificial filling foundation movement of ground water.
2.Gravel filter layer surrounding the periphery of the drain pipe drain.
3.In water conservancy projects wells, relief wells or inclined pipe filter.
4.For retaining wall backfill reinforcement, or for anchored retaining wall panel.
5.Reinforced flexible pavements, crack repair roads, prevent the reflection cracks of pavement.
6.In ternal vertical or horizontal drainage, dissipation of pore water pressure in soil.
7.Water impermeable geomembrane dam or embankment in the lower part of the back or the concrete.
8.The isolation layer between the road ballast and subgrade, isolation layer or
