Short Fiber Needled Punched Geotextile are usually made from a synthetic polymer such as polypropylene, polyester, polyethylene or polyamides and processed by needle punched or heat bonded methods. Geotextile is the permeable and durable geosynthetic widely used to separate, filter, reinforce, protect, retain or drain soil. Geotextile is the ideal materials for civil construction applications such as roads, harbors, reservoirs, canals, dams and many others retaining construction to improve soil stability, provide erosion control or aid in drainage.
● Reducing civil engineering overall cost
● Extend the project service life
● High performance of filtration, separation, reinforcement, erosion control,etc.
● High tensile strength & permeability and low elongation
● Corrosion resistant
● Easy installation, dimensional stabilization
(1) Reinforcement in backfilling of retaining walls, or panels used to anchor retaining walls. Construct a wrapped retaining wall or abutment.

(2) Reinforce the flexible pavement, repair the cracks on the road, and prevent the pavement from reflecting cracks.
(3) Increase the stability of gravel slopes and reinforced soil to prevent soil erosion and freezing damage of soil during low temperature.
(4) The isolation layer between the roadway and the roadbed, or the isolation layer between the roadbed and the soft foundation.
(5) Isolation between artificial fill, rockfill or material field and foundation, and isolation between different frozen soil layers. Filtration and reinforcement.
(6) The filter layer of the initial upstream dam surface of the ash storage dam or tailings dam, and the filter layer of the drainage system in the backfill of the retaining wall.
(7) A filter layer around the drain pipe or around the gravel drain.
(8) Filter layers for water wells, pressure relief wells or diagonal pressure pipes in water conservancy projects.
(9) Segregation of geotextiles between the road, airport, railway turnouts and artificial rockfills and foundations.
(10) The vertical or horizontal drainage of the earth dam is buried in the soil to dissipate the water pressure in the gap.
(11) Drainage behind the anti-seepage geomembrane in the earth dam or earth embankment or in the lower part of the concrete facing.
(12) Exclude water seepage around the tunnel, reduce the external water pressure on the lining and seepage water around each building.
(13) Drainage of the base of the ground-based sports ground.
(14) Roads (including temporary roads), railways, embankments, earth-rock dams, airports, sports fields, etc. are used to strengthen weak foundations.
