Film Geotextile
1.High-Efficiency Drainage:
Water-permeable yet soil-retaining, rapidly drains groundwater while preventing clogging.
2.Reinforcement Capability:
High tensile strength for load distribution and improved foundation stability.
3.Durability & Weather Resistance:
UV-resistant, acid/alkali-proof, with 10-20 years service life in outdoor environments.
4.Easy Installation:
Lightweight rolls , customizable by cutting/sewing to adapt to complex terrains.
5.Eco-Friendly & Cost-Effective:
Reduces aggregate usage and cuts project costs by over 30%.
Product Introduction:
Film Geotextile is a widely used geosynthetic material made from polymer fibers through processes such as weaving, needling, and non-woven technology. It integrates functions of filtration, drainage, separation, reinforcement, and protection in civil engineering projects.
