Products Introduction：
Geo Fabric Retaining Wall is a permeable geosynthetic material made from synthetic fibers such as polypropylene, polyester, etc., through processes such as needle punching, weaving, or hot rolling. It has high strength, flexibility, and corrosion resistance, and can play key roles in various geotechnical engineering such as filtration, drainage, isolation, and reinforcement. As a new type of engineering material, its structural design balances functionality and practicality, and can choose different specifications (such as thickness, unit area mass, aperture, etc.) according to different engineering needs, adapting to various construction scenarios.
Product Features：
1. Efficient filtration and permeability: With precise pore size design, it can effectively intercept soil particles, prevent soil erosion, and ensure smooth water infiltration, avoiding structural failure caused by blockage in engineering and balancing the infiltration relationship between water and soil.
2. Strong and tear resistant: Made of high-strength interwoven fibers, it has excellent tensile and wear resistance, can adapt to stress changes in complex terrain, is not easily damaged under soil settlement and external loads, and ensures the stability of engineering structures.
3. Excellent weather resistance: It has good UV resistance and can resist aging caused by long-term exposure to sunlight; Simultaneously resistant to acid and alkali, and resistant to chemical corrosion, it can maintain long-term performance in different soil environments (such as saline alkali land and polluted soil), significantly extending the service life of the project.
4. Convenient and economical construction: With a lightweight texture and much lower weight than traditional engineering materials, it is easy to cut, lay, and splice without the need for complex construction equipment and professional skills, which can significantly shorten the construction period, reduce labor and transportation costs, and improve the overall efficiency of the project.
5. Multi functional adaptation: In addition to the core filtering and reinforcement functions, it can also play an isolation role (separating soil, sand and gravel materials of different particle sizes), preventing the mixing of different media from affecting engineering performance, achieving "one material for multiple uses", and simplifying the construction process.
