Geotextile drainage
Geotextile Drainage has ultra-high permeability, and its drainage efficiency is 50%+ higher than that of traditional gravel layers. It integrates drainage, filtration and protection, is easy to construct, and saves 30% of costs. It is acid- and alkali-resistant, UV-resistant, and has a service life of more than 15 years. It is suitable for scenes such as roads, tunnels, and landfills. Its lightweight design can reduce the thickness by 50%, making it an efficient and economical drainage solution.
Geotextile drainage is a composite material consisting of geotextile and drainage core layer, used for drainage, filtration and isolation applications in civil engineering. It combines the excellent filtration performance of geotextile with the efficient water conduction capacity of drainage structure.
