Geotextile is usually made from a synthetic polymer such as polypropylene (PP), polyester (PET) etc. raw material and processed by woven & needle punched non woven or heat bonded methods. It is used as protection, filtration or separation layer alternative to diverse terrain such as soil, rock, sand and so on, also the UV Resistance and Thermal Bonded etc. performance is available.
As the professional geotextile fabric manufacturer and supplier in China, we could produce non woven geotextile fabric including: polyester (PET) staple fiber geotextile, polypropylene (PP) staple fiber geotextile, polyester (PET) continuous filament geotextile, polypropylene (PP) continuous filament geotextile.
Taking Filament spunbond nonwovens Geotextile as example:

It has superior water permeability, filtration, durability and deformation adaptability, and has a good plane drainage ability.
Functions filtration, reinforcement, drainage, separation, protection and stabilisation etc.
(1) For reinforcement in the backfill of the retaining wall, or for anchoring the panel of the retaining wall. Construction of wraparound retaining walls or abutments.
(2) Strengthen the flexible pavement, repair the cracks on the road, and prevent the pavement from reflecting cracks.
(3) Increase the stability of gravel slope and reinforced soil to prevent soil erosion and freezing damage at low temperatures.
(4) The isolation layer between the road ballast and the roadbed, or the isolation layer between the road star and the soft foundation.
(5) Isolation layer between artificial earth filling, rockfill or material field and foundation, and isolation between different frozen soil layers. Backfiltration and reinforcement.
(6) The filter layer of the initial upstream dam surface of the ash dam or tailings dam, and the filter layer of the drainage system in the backfill soil of the retaining wall.
(7) The filter layer around the drainage dark pipe or the gravel drainage dark ditch.
(8) The filter layer of water Wells, relief Wells or baroclinic pipes in water conservancy projects.
(9) Isolation layer of geotextiles between roads, airports, railway tracks and artificial rockfills and the foundation.
(10) The earth dam is drained vertically or horizontally and buried in the soil to dissipate the void water pressure.
(11) Drainage behind impermeable geomembrane or under concrete protection in earth DAMS or earth embankments.
(12) Eliminate water seepage around the tunnel, reduce the external water pressure borne by the lining and water seepage around the buildings.
(13) Drainage of artificial land foundation and sports ground foundation.
(14) Roads (including temporary roads) are used to strengthen weak foundations in projects such as railways, embankments, earth-rock DAMS, airports and sports grounds.
