Products Introduction：
Geosynthetic Textile is a new type of engineering material made from high molecular weight polymers through special processing techniques. It breaks the limitations of traditional civil engineering materials relying on natural sand, gravel, and clay. Through scientific material design and structural optimization, it achieves efficient regulation of natural environments such as soil and water bodies, and has become one of the key materials in modern civil engineering, water conservancy engineering, environmental protection engineering, and other fields. It has various forms, including needle punched non-woven fabric, woven geotextile, composite geotextile, etc., and can be selected according to different engineering needs.
Product Features：
1. Outstanding structural stability: The internal fibers or warp and weft structures are evenly distributed, forming a stable mechanical support system. When subjected to soil pressure, the synergistic effect between fibers can disperse stress and avoid structural damage caused by excessive local stress, which is the core foundation for enhancing engineering stability.
2. Multi functional integration: integrating functions such as filtering, drainage, isolation, and reinforcement. The precision of soil particle interception can be accurately controlled during filtration, and efficient water channels can be formed through pores during drainage. The isolation function can prevent the mixing of materials with different particle sizes, meeting the demand of "one material for multiple uses" in engineering.
3. Excellent material properties: Made of weather resistant polymer materials, it has stable performance in the temperature range of -40 ℃ to 80 ℃, and also has the ability to resist acid and alkali corrosion and microbial decomposition. Even if exposed to outdoor environments or in contact with sewage, saline alkali soil and other environments for a long time, its service life can still reach more than 20 years.
4. Strong adaptability to construction: lightweight texture, usually weighing between 100-600 grams per square meter, can be rolled and stored during transportation, saving space; Laying can be completed without the need for complex machinery, manual labor, or small equipment, and can be flexibly cut according to project dimensions to adapt to irregular construction sites.
