Products Introduction：
Geotextile 400g m² is a high-performance geotextile with high weight, made of high-quality polyester or polypropylene fibers, processed through advanced needle punching or weaving techniques. The weight of 400g/m ² gives it a more solid structure. As an important geosynthetic material, it can play multiple roles such as isolation, reinforcement, protection, and filtration in various engineering projects. Whether it is large-scale infrastructure construction or small and medium-sized engineering operations, this geotextile can provide reliable guarantees for engineering structures with its stable performance, effectively improving the overall quality and durability of the project.
Product Features：
1. Super strong bearing capacity: The high weight of 400g/m ² endows this geotextile with excellent tensile strength and tear strength, which can easily cope with the long-term effects of heavy loads. In projects such as roads and dams that bear high pressure, it can effectively resist deformation and damage, ensuring the stability of the engineering structure.
2. Excellent isolation performance: Its tight fiber structure can accurately separate materials such as soil and sand with different particle sizes, prevent various materials from mixing with each other, avoid structural strength decline caused by material mixing, and maintain the integrity of each layer of the project structure.
3. Excellent filtration and drainage performance: While effectively blocking soil particle loss, it allows water to pass smoothly, achieving good filtration and drainage effects, reducing the pressure caused by accumulated water in the project, and lowering the risk of structural erosion.
4. Super durability: The thickened material gives it stronger resistance to wear and corrosion, and can resist the erosion of natural factors such as acid and alkali substances, microorganisms, and ultraviolet rays. It can also maintain stable performance in harsh environments, greatly extending its service life.
5. Wide adaptability: It has good flexibility and plasticity, and can be flexibly cut and laid according to the terrain and size requirements of different projects. The construction process is convenient and efficient, and can adapt to various complex engineering environments.
