Polyester Filament Geotextile
Core Features
• Superior Mechanical Performance
The three-dimensional fibrous network structure provides high tensile strength and excellent creep resistance. It outperforms short-fiber geotextiles of equivalent weight, effectively distributing loads and preventing foundation deformation. Particularly suitable for complex stress conditions such as retaining walls and reinforced embankments.
• Efficient Drainage and Filtration Capability
The material has a loose structure with tortuous pore distribution, offering excellent in-plane drainage and vertical permeability. It allows water to pass through while preventing soil particle migration, achieving a "drainage without soil loss" filtration function.
Polyester filament geotextile is a nonwoven geosynthetic material made from polyester filaments through spinning and needle-punched consolidation processes. It possesses key advantages such as high strength, aging resistance, UV resistance, water permeability while retaining soil, and reinforcement and separation capabilities, making it an indispensable engineering material in modern infrastructure construction.

• Exceptional Environmental Resistance
Withstands temperatures up to 230 °C while maintaining structural integrity;
Highly resistant to ultraviolet (UV) radiation, suitable for long-term outdoor exposure;
Resistant to acids, alkalis, and microbial degradation, making it ideal for harsh environments such as landfills and chemical industrial zones.
• Excellent Ductility and Adaptability
Flexible and conformable to uneven substrates, accommodating settlement and deformation. Reduces the risk of damage during installation and ensures reliable long-term performance.
II. Main Application Field
1. Hydraulic Engineering
Used in filtration and seepage control systems for embankments, reservoirs, and riverbank protection, preventing seepage-induced damage and soil erosion, ensuring engineering safety and stability.
2. Transportation infrastructure
Laid within the subgrades of highways and railways, it serves functions of reinforcement, separation, and drainage, preventing issues such as frost heave and reflective cracking, thereby extending the service life of roads.
3. Environmental Engineering
Serves as a protective and drainage layer for impermeable membranes in landfills, preventing leachate from contaminating groundwater while enhancing overall structural stability.
4. Soft Soil Treatment and Port Engineering
Applied in soft ground reinforcement, coastal embankments, seaports, and wharf projects to improve load-bearing capacity and control differential settlement.
5. Ecological Restoration and Landscape Greening
Integrated with vegetated slope protection techniques to achieve both slope stabilization and ecological greening, widely used in mountain restoration and urban landscape development.
