Polyester Long Fiber Geotextile
Product survey
SK Polyester long fiber anti-sticking needle embroidering Geotextile is a new building material used in rock earthworks and civil works. It is produced by the way of Polyester long fiber netting and consolidation, and its fibers are arranged into three-dimensional structure.
Performance feature
Besides chemical strength features such as good tension, tearing, breaking and puncture resistance, it has good vertical and horizontal drainage performance, good tension performance and good chemical functions such as biology, acid, alkali and aging resistance. It also has wide hole diameter range, zigzag gap layout and good penetration and filtering performance.
Application and function
1. Isolation between different materials: Use between roadbed and foundation of non-laying (lain) road and airport road, use between earthwork film and sand drainage layer, use between foundation and road bank earth, bearing additional load, use on additional load, use between foundation earth and foundation pile, use below sidewalk, parking lot and playground, and use between new and old asphalt layers.
2. Reinforcing soft foundation: Use on soft foundation of non-laying road surface, use on soft foundation of airport road, railway, landfill yard and playground, prevent foundation earth from breaking earthwork film, and prevent foreign object or stone layer in landfill yard from breaking earthwork film.
3. Anti-filter: Protect earthwork net below landfill yard that has seepage, prevent earth particle from entering, protect earthwork composite material, and prevent earth particle from entering.
4. Drainage: Use for drainage below earthwork film, drainage below playground and drainage below railway ballast.
