Geotextile for Retaining Wall
1. Efficient filtration and stable structure: Geotextile has a uniform pore structure, which can effectively intercept soil particles and allow water to penetrate smoothly, avoiding instability of structures such as roadbeds and dams caused by water flow erosion. It plays a key filtering role in water conservancy and transportation engineering.
2. Super durable and adaptable to complex environments: Made of high-strength synthetic materials, it has excellent UV resistance, acid and alkali resistance, and corrosion resistance. It can maintain stable performance for a long time in various harsh environments such as high temperature, low temperature, and humidity, extending the service life of the project.
3. Convenient construction and cost saving: The material is lightweight and flexible, and can be flexibly cut and laid according to project needs without the need for complex construction equipment and technology, greatly shortening the construction period and reducing labor and equipment investment costs.
Products Introduction：
Geotextile for Retaining Wall is a high-performance geosynthetic material designed specifically for retaining wall engineering, using high-quality polyester (PET) or polypropylene (PP) filament fibers woven or non-woven through special processes. It undertakes key functions such as isolation, reinforcement, filtration, and drainage in the retaining wall system through optimized structural design, effectively enhancing the stability, durability, and safety of the retaining wall structure. It is one of the core materials for improving the performance of retaining walls in modern geotechnical engineering.
Product Features：
1. High strength reinforcement performance: The material has undergone special tensile treatment and has extremely high tensile strength and elastic modulus, which can effectively disperse the lateral soil pressure borne by the retaining wall, reduce wall deformation, improve the overall structural bearing capacity, and prevent the wall from collapsing due to uneven stress.
2. Precise isolation function: The fiber structure forms a stable barrier, which can strictly isolate the backfill soil of the retaining wall from the foundation soil, different graded sand and gravel materials, avoid mixing of different soil layers or materials, prevent structural layering failure caused by material infiltration and mixing, and ensure the integrity of each structural layer of the retaining wall.
3. Efficient filtration and drainage synergy: The unique porous structure can intercept soil particles, prevent the loss of backfill soil, and quickly discharge accumulated water behind the wall, reducing pore water pressure, minimizing water erosion and pressure on the wall, and avoiding the decrease in wall strength caused by accumulated water.
4. Excellent durability: It has excellent resistance to UV aging, acid and alkali corrosion, and biodegradation, and can maintain stable performance in complex environments such as soil and groundwater for a long time. Its service life can reach more than 50 years and it can adapt to various climatic and geological conditions.
5. Good construction adaptability: The material is lightweight and flexible, and can be flexibly cut according to the shape and size of the retaining wall. The laying process is simple and convenient, and it can closely fit the wall surface and backfill soil, ensuring perfect compatibility with the engineering structure and improving construction efficiency.
