Polyester Filament Nonwoven Geotextile fabric

• 1. High Strength: Made from high-strength polyester filaments, the fibers are entangled through a needle punching process, resulting in excellent tensile, tear, burst, and puncture strength, maintaining structural stability in harsh engineering environments.
• 2. Durability and Corrosion Resistance: Polyester material offers excellent chemical resistance, acid and alkali resistance, aging resistance, mildew resistance, and excellent resistance to soil and microorganisms, ensuring a long service life. 3. Good Water Permeability: The numerous pores between the fibers provide excellent vertical water permeability, enabling timely and effective drainage of pore water and lowering the groundwater level.
• 4. Excellent Filtration and Reverse Drainage: When water flows from fine-grained soil into coarse-grained soil, the geotextile effectively prevents the loss of fine particles while allowing water to flow smoothly through, preventing siltation and protecting soil stability.
• 5. Protective Properties: As a buffer layer, it disperses stress and protects the base soil from damage caused by external forces.
• 6. Convenient Construction: The material is lightweight and comes in roll form, making it easy to transport, cut, and lay, increasing construction efficiency.

Due to its outstanding performance, polyester filament geotextiles are widely used in numerous civil engineering fields, including water conservancy, transportation, municipal administration, and environmental protection, primarily for reinforcement, isolation, filtration, drainage, and protection.

1. Water Conservancy Projects

• Dyke and Slope Protection Projects: Used as a filter layer in dykes and river slope protection to prevent soil erosion and ensure smooth drainage.
• Reservoirs and Canals: Used as the base layer of the anti-seepage system in reservoirs and canals, protecting the anti-seepage material (such as geomembrane) from puncture and providing drainage and air evacuation.
• Seawalls and Harbors: Used to reinforce soft foundations, increase bearing capacity, and prevent foundation hollowing caused by wave erosion.

2. Transportation Engineering

• Highway and Railway Roadbed: Laid between the roadbed and the foundation, it provides isolation and reinforcement. It prevents mixing of different soil materials (such as stone sinking into soft soil), distributes the load, reduces uneven subgrade settlement, and extends the service life of the road.
• Airport Runways and Parking Lots: The principle is similar to that of road engineering, improving foundation stability.

3. Municipal and Environmental Engineering

• Landfills: This is a very important application area. It serves as a filter and protective layer, used in conjunction with geomembranes, located above and below the anti-seepage membrane, to guide leachate and protect the membrane from damage.
• Sewage Treatment Plants and Tailings Ponds: Used for pond bottom or dam reinforcement and backfiltration.
• Landscape lakes and artificial wetlands: Used as a protective layer in lake bottom anti-seepage systems.

4. Other projects

• Construction projects: Used for foundation treatment to prevent lateral displacement of foundation soil.
• Agricultural projects: Used for farmland drainage systems to prevent clogging of drainage ditches.
