Products Introduction：
Geotechnical Cloth, also known as geotextile, is a permeable synthetic fiber fabric made mainly of polypropylene (PP) or polyester (PET). It is widely used in geotechnical and municipal engineering, with core functions including isolation, filtration, drainage, reinforcement and protection. Geotextiles are divided into non-woven and woven types: non-woven ones, formed by needle punching or hot pressing, have good water permeability and strong filtration performance and are the most commonly used; woven ones, made by warp and weft weaving, have high strength and low elongation, suitable for reinforcement scenarios. It has the characteristics of high strength, durability, good water permeability and air permeability, and easy construction, and is typically applied in transportation, water conservancy, environmental protection, construction and other fields such as highway subgrade isolation, dike anti-filtration, garbage landfill liner protection and foundation reinforcement.

Product Applications：
Geotechnical cloth has the most extensive and crucial application in water conservancy engineering. Its core functions of isolation, filtration, drainage, reinforcement, and protection precisely meet the core needs of water conservancy projects for erosion control, seepage prevention, slope stabilization, and drainage, making it a key material for ensuring the safety and stability of water conservancy projects. With its advantages of light weight, convenient construction, aging resistance, and freeze-thaw resistance, this material is well-suited to complex operating environments in water conservancy projects, such as deep water, humidity, and saline-alkali conditions. It improves construction efficiency, reduces construction costs, and provides a solid guarantee for the long-term stability of the project.
In dam, slope protection, and river and canal engineering, geotextile plays a particularly prominent role. In dam and slope protection projects, geotextile is laid on the surface or inside the slope to act as a filter and stabilize the slope, preventing soil particle loss and avoiding hidden dangers such as piping and landslides. At the same time, it drains seepage water from the dam body, reduces internal water pressure, minimizes settlement and cracking, and effectively resists water erosion during the flood season. In river and canal engineering, the combined use of geotextiles and geomembranes can reduce water seepage by more than 30%, significantly improving seepage prevention performance. Simultaneously, it protects riverbanks from erosion, prevents collapse, and extends the service life of the project.
In land reclamation and wharf projects, geotextiles are a core material for soft soil foundation reinforcement. Through their reinforcing effect, they significantly improve the tensile strength and bearing capacity of soft soil. Their auxiliary drainage function accelerates soft soil consolidation, effectively addressing the challenges of difficult soft soil treatment and large settlement, laying a solid foundation for subsequent construction. Whether in main water conservancy projects or auxiliary construction phases, geotextiles play an irreplaceable role, becoming an indispensable core supporting material in water conservancy projects.
Geotechnical Cloth, a type of permeable synthetic fiber fabric, focuses on isolation, filtration, drainage, reinforcement, and protection. With its advantages of durability, efficiency, and versatility, it is widely used in various fields such as water conservancy, transportation, environmental protection, municipal engineering, construction, and agriculture. It can effectively solve engineering problems such as mixed soils, soil erosion, settlement, and leakage. It is suitable for complex environments such as soft foundations, deep water, and saline-alkali soils, playing a crucial role in improving project stability, extending service life, and reducing construction costs. Based on functional requirements, it can be divided into three main types: non-woven, woven, and composite, meeting the selection needs of different engineering scenarios.
