High-Strength Long Fiber Geotextile For Civil Engineering Applications
Product Introduction
Long fiber geotextile is the polyester method by spinning needle consolidation directly made, product specifications from 100-800g/m2 arbitrary choice, it is a geotechnical engineering and civil engineering application of a geosynthetic material, is made by polyester filament mesh and consolidation method, the fibers arranged into a three-dimensional structure. In addition to good mechanical properties, it also has good vertical and horizontal drainage performance and good extension performance and high biological resistance, acid and alkali resistance, aging resistance and other chemical stability. At the same time, it also has a wide aperture range, zigzag pore distribution, excellent permeability and filtration performance.
Product Properties
High strength, aging resistance, acid and alkali resistance, wear resistance, good flexibility, easy construction.
Product Application
1. The filtration of dam and slope protection, the isolation and seepage prevention of channel;
2. Foundation isolation, reverse filtration, drainage, slope, retaining wall, pavement reinforcement and drainage of roads, railways and airport runways;
3. Soft foundation treatment of port projects, reinforcement and drainage of beach embankments, harbour wharves and breakwaters;
4. Polyester filament geotextile has been widely used in the field of infrastructure construction, and is gradually applied to a wider range of fields.
