Polyester geogrid is a new type of high-quality geosynthetics substrate, it use high-strength polyester fiber or polypropylene fiber as raw material, by use warp-oriented structure with special process of dipping coating treatment. The warp and weft of the fabric are free from each other, the crossings are combined with high-strength filament bundles to form a firm bond and give full play to their mechanical properties. Specification: Width: 3mm or 4mm or as clients request Length: 100m or as clients request Function: High tensile strength Low elongation Anti-erosion, anti-aging Good affinity with base material Light weight, water drainage Application: Roadbed reinforcement in highway, railway and municipal road. Reinforcement and separation in dam and river, improve soft soil bearing Capacity and stability. Roadbed slope reinforcement, retaining wall reinforcement.
