Products Introduction：
Geosynthetic Cloth is a new type of engineering material mainly made of high molecular weight polymers, processed through weaving, needle punching, hot melt, spunbond and other processes. It covers multiple categories such as woven geotextiles, non-woven geotextiles, composite geotextiles, etc. With diverse structures and properties, it undertakes key functions such as reinforcement, isolation, filtration, drainage, and protection in civil engineering, water conservancy engineering, environmental engineering, and other fields. As an innovative solution to replace traditional materials in modern engineering construction, its core value lies in improving engineering stability, extending service life, and reducing comprehensive costs through the high performance and functional integration of materials. It is an important basic material for promoting engineering technology upgrading and sustainable development.
Product Features：
1. Multi functional integration: Breaking through the functional limitations of traditional single materials, it can simultaneously meet multiple engineering needs. For example, composite geotextiles can provide high-strength reinforcement through woven layers and achieve efficient filtration and drainage through non-woven layers; Some products can also be combined with anti-seepage membranes, grilles and other materials to form an integrated solution of "reinforcement+anti-seepage+drainage", meeting the diverse needs of complex engineering.
2. Controllability of mechanical properties: By selecting raw materials and adjusting processes, the mechanical indicators such as tensile strength, tear strength, and burst strength of the product can be precisely controlled. From low strength products (tensile strength 5-20kN/m) suitable for lightweight sites to high-strength materials (tensile strength 50-300kN/m) that meet the requirements of heavy-duty engineering, they can be flexibly matched according to the characteristics of engineering loads to ensure structural stress balance.
3. Environmental adaptability and durability: weather resistant polymer materials (such as polyester and polypropylene) are used, and they are treated with UV resistance, aging resistance and corrosion resistance to maintain stable performance in extreme environments. Whether it is high temperature and drought, severe cold and freezing, acidic and alkaline soil, or salt spray environment, it can resist natural erosion for a long time, and its service life can generally reach 10-30 years, greatly reducing the frequency of later maintenance.
4. Convenience and economy of construction: Lightweight texture (usually 100-1000g/m ² per unit area), strong flexibility, can be flexibly cut and spliced according to project dimensions, without the need for large specialized equipment. The laying process is simple and efficient, and can be operated manually or mechanically. It can adapt to complex terrain (such as steep slopes, curved surfaces, irregular foundations), significantly shorten the construction period, reduce labor and equipment costs, and has a comprehensive cost-effectiveness far exceeding traditional materials such as sand and concrete.
