Geotextile Blankets
1. High strength and toughness: Using high-quality materials such as plastic fibers, geotextiles can maintain excellent strength and elongation performance in both dry and humid environments, with high tensile strength, effectively enhancing the tensile strength and deformation resistance of soil, and stabilizing building structures.
2. Corrosion resistance: With excellent chemical stability, it can withstand corrosion for a long time in soil and water environments with different pH values, resist erosion from acidic and alkaline substances, and impurities carried by floods.
3. Excellent permeability: There are gaps between the fibers, and the permeability is good. It can construct drainage channels inside the soil, timely discharge excess liquids and gases, and effectively intercept soil particles, fine sand, etc. to prevent problems such as "pipe surge" and "soil flow", ensuring the stability of water and soil engineering.
4. Easy construction: The material is lightweight, soft, and easy to transport and lay, which can greatly improve construction efficiency, save labor and material costs, and can also be flexibly cut and spliced according to project needs.
Products Introduction：
Geotextile Blankets are permeable geosynthetic materials made from high molecular weight polymers such as polypropylene and polyester through processes such as needle punching, weaving, and hot rolling. It is not a traditional "fabric", but a functional material designed specifically for scenarios such as geotechnical engineering and hydraulic engineering. Its core function is to solve problems such as reinforcement, drainage, isolation, and protection in engineering through its own physical properties and structural characteristics. It is one of the indispensable key materials in modern civil engineering.
Product Features：
1. High strength and toughness, stable structure
Made of high-quality polymer fibers, it can maintain stable mechanical properties in different environments such as dry and humid. The tensile strength can reach several times that of ordinary fabrics, and can withstand the tensile force generated by soil settlement, water flow impact, etc., effectively enhancing the deformation resistance of soil, reducing the risk of cracks and collapses, and providing long-term support for engineering structures.
2. Corrosion resistant, long-lasting and durable
The material itself has excellent chemical stability and can withstand erosion from complex environments such as acidic and alkaline soils, industrial wastewater, and groundwater. Even under extreme conditions such as long-term immersion, high temperature, and low temperature, the performance is not easily degraded, and the service life can reach decades, greatly reducing the maintenance cost in the later stage of the project.
3. Permeable and breathable, water and soil complement each other
The porous structure between fibers combines the dual functions of "permeability" and "filtration": on the one hand, it can quickly discharge accumulated water and gas in the soil, avoiding structural damage caused by pressure accumulation; On the other hand, it can intercept soil particles, fine sand, etc., prevent soil erosion, and fundamentally solve engineering hazards such as "pipe surge" and "soil flow".
4. Flexible and convenient, with strong adaptability
The texture is light and soft, usually weighing less than 1 kilogram per square meter, and does not require large equipment for transportation and laying. At the same time, it can be flexibly cut and spliced according to engineering requirements, adapting to irregular terrains such as slopes, roadbeds, and dams, significantly improving construction efficiency.
