Filament nonwoven geotextile made of needle punched PET material. Nonwoven geotextiles have strong penetration, flexibility and high permeability. Nonwoven geotextile materials are made of polyester fiber (PET) and polypropylene (PP). This material selection is based on user requirements

Product introduction:

Filament spunbonded needle punched geotextile is made of polyester filament and curing method, and its fiber array has three-dimensional structure. In addition to good mechanical properties, it also has good vertical and horizontal drainage performance, extension performance, permeability, filtration performance, high acid-base resistance, aging resistance and other good chemical properties.

Product features:

1. The mesh is easy to be blocked, because the mesh structure formed by infinite mesh has variability and mobility.

2. It has strong permeability and can maintain good permeability under earth pressure.

3. It has corrosion resistance and uses chemical fibers such as polypropylene or polyester as raw materials. It has 4. Acid and alkali resistance, no corrosion, no moth, anti-oxidation.

4. Convenient construction, light weight and convenient use.

Product application:

1. Reinforcement in the backfill of retaining wall or used to anchor the panel of retaining wall. Construct a wrapped retaining wall or abutment.

2. Reinforce flexible pavement, repair pavement cracks and prevent pavement reflection cracks.

3. Increase the stability of gravel slope and reinforced soil to prevent soil erosion and soil freezing damage at low temperature.

4. Isolation layer between ballast and subgrade, or between subgrade and soft foundation.

5. Isolation layer of artificial fill, rockfill or material yard and foundation, isolation, filtration and reinforcement of different frozen soil layers.

6. The initial upstream dam surface filter layer of ash storage dam or tailings dam and the filter layer of drainage system in retaining wall backfilling.

7. Filter layer around drain pipe or gravel drain.

8. Filter layer of water well, relief well or inclined pressure pipe in hydraulic engineering.

9. Geotextile isolation layer between road, airport, railway ballast, artificial rockfill and foundation.

10. The vertical or horizontal drainage inside the earth dam is buried in the soil to dissipate the water pressure in the pores.

11. Drainage behind impervious geomembrane or under concrete protective layer of earth dam or embankment.

12. Reduce water seepage on and around the tunnel lining.

13. Manually fill the drainage of the ground sports ground.

14. Roads (including temporary roads) are used to strengthen the weak foundation of railways, embankments, earth rock dams, airports, sports grounds and other projects.
