Product introduction

Polyester filament geotextile product introduction: It has high strength and strong puncture resistance; it is acid and alkali-resistant, anti-corrosion, anti-microbial, and anti-aging; it has excellent water permeability, filtration, and soil retention, and plays a role in isolation, drainage filtration, and protection. Function: Low cost and excellent price.

Performance characteristics

1. High strength: Filament geotextile is made of high-strength polyester fiber, with excellent tensile resistance, can effectively withstand soil pressure and external loads, and ensure the stability of the structure.

2. Good water permeability: This material has excellent water permeability and can quickly drain water without affecting the stability of the soil to avoid pressure and damage caused by accumulated water

3. Strong corrosion resistance: Polyester fiber has excellent acid and alkali resistance and corrosion resistance, and is suitable for use in harsh environments such as water conservancy and environmental protection, ensuring long-term use without being affected by external factors

4. Durability: Due to its excellent weather resistance, polyester filament geotextiles can provide long-term stable performance, extending the service life of geotechnical projects and reducing subsequent maintenance costs.

5. UV Resistance: Polyester filament geotextiles have strong UV resistance, maintaining their performance even under intense sunlight and preventing loss of functionality due to aging.

6. Excellent Antibacterial Properties: This material inhibits the growth of microorganisms, making it suitable for environments where protection from decay and contamination is crucial, ensuring the long-term safety of engineering structures.

With these characteristics, polyester filament geotextile is widely used in water conservancy projects, transportation facilities, landfills, and other fields, and is an indispensable and important material in civil engineering.
