Products Introduction：
Geotex Fabric is a functional engineering material made from high molecular weight polymers (such as polypropylene, polyester, polyethylene, etc.) through processes such as non-woven, woven, and needle punched processing. Its core functions cover five dimensions: filtration, drainage, isolation, reinforcement, and protection. As a fundamental category of geosynthetic materials, it has been widely used in civil engineering as a key bridge for "material interlayer coordination+environmental protection" due to its lightweight, flexible, and durable characteristics. It is widely used in fields such as roads, water conservancy, environmental protection, and municipal engineering.
Compared with traditional engineering materials such as sand and concrete, Geotex Fabric focuses more on the combination of "functionality and ecology" - it can optimize the performance of engineering structures through physical effects, reduce resource consumption, and meet the needs of modern engineering for "efficiency, environmental protection, and low cost". It is an important material for promoting the lightweight and green development of civil engineering.
Product Features：
1. Functional composite, one material with multiple uses
It has multiple functions such as filtration, drainage, and isolation: as a filter layer, it can intercept soil fine particles to prevent blockage; as a drainage layer, it can quickly divert accumulated water; as an isolation layer, it can prevent the mixing of different materials, without the need for multiple materials to be stacked together, simplifying engineering design and construction processes, and adapting to multi process composite engineering scenarios.
2. Mechanically stable, resistant to damage and durable
The longitudinal and transverse fracture strength can reach 5-50kN/m (depending on the type), with excellent tear and tensile resistance, and can withstand the stress generated by heavy machinery compaction, water flow erosion, and soil displacement; After UV and acid-base treatment, the performance is stable in environments ranging from -30 ℃ to 80 ℃, with a service life of up to 5-20 years, reducing maintenance and replacement costs in the later stages.
3. Flexible and adaptable, with a wide range of scenarios
The texture is soft and has good extensibility, which can tightly adhere to irregular base layers such as slopes, ditches, and curved structures, without blind spots for laying; Lightweight (50-1000g/m ²), easy to cut, suitable for heavy-duty projects such as large dams and highways, as well as light projects such as courtyard renovation and small-scale water conservancy.
4. Eco friendly, permeable and breathable
Using non-toxic and harmless raw materials, the production process has no harmful emissions, and after laying, it does not pollute the soil and water bodies; The porous structure allows for the free infiltration of air and water, providing conditions for the growth of vegetation roots, and can directly cooperate with ecological greening projects to achieve synchronous promotion of "engineering protection+ecological restoration".
5. Economically efficient and easy to construct
The unit price of materials is lower than traditional protective materials, and construction does not require large equipment. It can be quickly laid manually, and the overlap width is ≥ 10cm to ensure integrity. The construction efficiency is 30% -50% higher than that of sand and gravel filter layers; The utilization rate of raw materials is high, and the comprehensive engineering cost can be reduced by 10% -20%.
