Products Introduction：
Geofabric for Retaining Walls is a high-performance geosynthetic material designed specifically for retaining wall engineering. It is made from high molecular weight polymers such as polyester and polypropylene, and is produced through advanced processes such as needle punching, weaving, or non-woven. As a key functional material in the retaining wall system, its core function is to optimize the stress state of the wall structure, enhance overall stability, and extend the service life of the retaining wall.
In traditional retaining wall engineering, insufficient soil permeability, shear strength, and soil erosion often lead to wall cracking, settlement, and even collapse. Geofabric for Retaining Walls, with its unique physical and mechanical properties, can effectively address these pain points. It can not only filter soil particles and prevent the loss of fillers, but also play a role in drainage, isolation, and reinforcement, providing comprehensive protection and support for retaining walls. It is an indispensable and important material in modern geotechnical engineering.
Product Features：
1. Excellent filtration performance: This geotextile has precise pore size distribution, allowing water to freely pass through while effectively intercepting soil particles, avoiding the loss of fillers due to water flow erosion. Its filtering accuracy has been rigorously tested and can be selected according to different soil types (such as sandy soil, loam soil, clay) to ensure stable filtering effect under various geological conditions, prevent voids behind the retaining wall, and ensure the safety of the wall structure.
2. Excellent drainage performance: The product has formed rich three-dimensional permeable channels inside, with strong drainage capacity, which can quickly discharge pore water and surface water behind the retaining wall, reducing soil pressure and pore water pressure. This feature can effectively reduce the immersion and erosion of walls caused by factors such as rainwater, avoiding wall overturning or deformation due to excessive water pressure, especially suitable for rainy areas or engineering scenarios with high groundwater levels.
3. High strength and tensile resistance: Made of high-strength polymer materials, it has excellent tensile strength, tear strength, and burst strength. During the stress process of the retaining wall, geotextile can withstand the lateral thrust of the soil and evenly transmit it to the wall structure, playing a reinforcing role and enhancing the overall anti sliding and anti overturning ability of the retaining wall. At the same time, its good elongation can adapt to small deformations of soil and avoid material damage caused by local stress concentration.
4. Good chemical stability and weather resistance: excellent resistance to acid and alkali corrosion, aging, ultraviolet radiation and high and low temperature. Under complex soil and natural climate conditions, product performance is not easily degraded and can maintain a stable working state for a long time. Whether in saline alkali land, polluted soil, or harsh weather conditions such as extreme cold and heat, it can effectively resist the erosion of environmental factors and extend the service life of retaining walls.
5. Convenient construction performance: The product has a soft texture, light weight, and is easy to cut, lay, and splice. During the construction process, there is no need for complex mechanical equipment, and it can be flexibly adjusted according to the actual size of the project, greatly improving construction efficiency. At the same time, its good flexibility allows it to closely fit the contour of the retaining wall and the soil surface, ensuring construction quality and reducing construction period and cost.
