Geotextile fabric
Property
1. High tensile strength, low deformation and have a high capability
2. Durability: steady property, resolve resistance, air slaked and can keep the
original property for a long time.
3. Anti-erosion: anti-acid, anti-aklia, insects and mould resistance
4. Permeability, could control the sieve size to retain certain permeability
Geotextile is a kind of new building materials,the raw material is polyester, polypropylene, acrylic, nylon and other synthetic polymers. According to the manufacturing methods are divided into: woven geotextile and non-woven geotextile two types.General engineering mainly use the non-woven geotextile .
Geotextile is impervious, filter, drainage, isolation, reinforcement and protection, sealing and other functions, it compared with the conventional masonry and concrete materials anti-seepage effect, low investment, simple construction technology, short time limit, good anti-seepage effect, channel high effective utilization coefficient, etc

3. Key Applications
• Civil Engineering: Roadbed reinforcement (prevents soil subsidence), pavement separation (isolates aggregates and soil), and slope protection (reduces erosion).
• Water Conservancy & Hydraulic Engineering: Riverbank stabilization, reservoir lining filtration, drainage systems for irrigation canals, and flood control projects.
• Environmental Protection: Landfill liner protection (prevents contaminant leakage), sewage treatment filtration, and ecological restoration (vegetation growth support).
• Construction & Infrastructure: Foundation drainage for buildings, basement waterproofing, and soil stabilization in airports, ports, and railway projects
