Products Introduction：
Geotextile Filter Cloth is a new type of engineering material made from synthetic fibers (such as polypropylene, polyester, etc.) through processes such as needle punching, weaving, or weaving. It has multiple functions such as filtration, drainage, isolation, and reinforcement, playing a key role in various civil engineering and environmental protection projects. It can effectively solve the shortcomings of traditional filtration materials in durability, filtration efficiency, and provide reliable guarantees for the stability and safety of engineering.
Product Features：
1. Excellent filtration performance: Through precise pore size design, it can efficiently intercept small particles in the soil, prevent their loss with water flow, and ensure smooth water infiltration, maintain soil water balance, and avoid engineering hazards such as piping.
2. High strength and durability: Made of high-quality synthetic fibers, it has extremely high tensile strength and tear strength, and can withstand various loads in engineering. At the same time, it also has excellent resistance to ultraviolet radiation, chemical corrosion, and biodegradation, and can work stably for a long time in harsh environments with a long service life.
3. Good water permeability: The special weaving process creates a large number of connected pores inside the fabric, allowing water to quickly pass through and timely discharge accumulated water in the engineering structure, reducing pore water pressure and protecting the stability of the engineering structure.
4. Construction convenience: Lightweight texture, good flexibility, easy to cut, transport, and lay. Whether on flat or complex terrain, construction can be carried out conveniently and quickly, greatly improving construction efficiency and shortening the project cycle.
