China Hdpe Geomembrane Sheet Suppliers – Hot Sale Filament Nonwoven Geotextile Sheet – LANHUA GROUP

1. Filtration: When water passes from a fine-grained to a coarsely grained layer, Wholesale filament nonwoven geotextile can retain fine particles well. Such as when water flows from a sandy soil into a high quality filament nonwoven geotextile factory price wrapped gravel drain.
2. Separation: To separate two layers of soil with different physical properties, such as the separation of road gravel from soft sub-base materials.
3. Drainage: To drain liquid or gas from the plane of the fabric, which leads to draining or venting of the soil, such as the gas vent layer in a landfill cap.
4. Reinforcement: To improve the load-bearing capacity of a specific soil structure, such as the reinforcement of a retaining wall.
5. Protective: When the water flows to the soil, it will concentrate the stress diffusion effectively, the transmission or the decomposition, prevents the soil to receive the external force action but the destruction, its protection soil.
6. Resistance to puncture: Combined with a geomembrane, the composite waterproof and impermeable material plays a role in preventing puncture.
High tensile strength, good permeability, air permeability, high-temperature resistance, anti-freezing, anti-aging, corrosion resistance, no – moth. Needle-punched nonwoven high quality filament nonwoven geotextile factory price is a geosynthetic material widely used. Widely used in railway subgrade reinforcement, road surface maintenance, sports hall, embankment protection, hydraulic construction isolation, tunnel, coastal beach, reclamation, environmental protection, and other projects

1. To reinforce the backfill of retaining wall or to anchor the faceplate of retaining wall. Build wrapped retaining walls or abutments.
2. Reinforcing flexible pavement, repairing cracks on the road, and preventing reflective cracks on the road surface.
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 ballast and roadbed or between the roadbed and soft ground.
5. The isolation layer between artificial fill, rockfill or material field and foundation, the isolation, filtration, and reinforcement between different frozen soil layers.
6. The filter layer of the upper reaches of the initial ash storage dam or tailings dam, and the filter layer of the drainage system in the backfill of the retaining wall.
7. The filter layer around the drainage pipe or gravel drainage ditch.
8. The filters of water wells, relief wells, or oblique pressure pipes in hydraulic engineering.
9. Wholesale filament nonwoven geotextile factory price isolation layer between the highway, airport, railway slag, and artificial rockfill and foundation.
10. Vertical or horizontal drainage within the earth dam, buried in the soil to dissipate the pore water pressure.
11. Drainage behind impervious geomembrane or under concrete cover in earth dams or embankments.
