Ⅰ.Product Introduction
Filament woven geotextiles is a geosynthetic material used in geotechnical engineering and civil engineering. It is made by web formation and consolidation of polyester filament, and its fibers are arranged in a three-dimensional structure.
Ⅱ.Product Series
Filament woven geotextiles are divided into polypropylene, polyester, nylon, polyethylene and other filament woven tgetextiles according to fiber types; mould-bag fabric, anti-filter fabric, composite base fabric and so on according to the use .
Ⅲ.Product Specifications
The main specifications of the product are expressed by the longitudinal breaking strength. The width and unit area mass indicate the auxiliary specifications. The recommended series are as follows: longitudinal breaking strength (kN/m): 35, 50, 65, 80, 100, 120, 140, 160, 180 , 200, 250, etc.; width (m): 2.0, 3.0, 4.0, 4.5, 5.0, 5.5, 6.0, and the like.
Ⅳ.Production Application
Reverse-filtration of dykes and slope protection of irrigation works, isolation and anti-seepage of channels; foundation isolation of roads, railways and airport runways, reverse-filtration, drainage, reinforcement and drainage of soil slope, retaining wall and pavement; soft foundation treatment of port engineering , reinforcement and drainage of beach levees, harbor piers and breakwaters;
