1, the laying of the foundation and the substrate between the latest professional drainage network, for discharging water between the foundation and the substrate, blocking capillary water and drainage networks have effectively integrated into the edge of the drainage system. This structure is automatically shortened foundation drainage pathways, drainage greatly reduce the short time, and can make use of the number of foundation material selection to reduce (to use materials with more fines professional drainage network, low permeability). You can extend the life of the road. Three-dimensional composite drainage network is a new geosynthetics. Composition structure is a three-dimensional geonet core, both sides have a needle stick perforated nonwoven geotextile. Three-dimensional geonet core includes a thick vertical rib special Professional drainage network, as well as the top and bottom of each one oblique ribs. Can be quickly discharged groundwater road, there is a void to maintain its own system of professional drainage network market, can block the capillary water under high loads. At the same time, it can also play the role of isolation and foundation reinforcement. A new geosynthetics. Three-dimensional composite drainage network is made of a unique three-dimensional geonet double-sided adhesive geotextile. Combination of geotextiles (filtration effect) and geonet (drainage and protection), to provide a complete "filtration - drainage - protection" effect. Three-dimensional composite drainage network unique three-dimensional structure of the core network in the whole course can withstand high compression loads, and to maintain a considerable thickness, provide good hydraulic conductivity. Neijiang professional drainage network, Edison, new materials, professional manufacturers drainage network provided by New Materials Co., Edison. Edison New Materials Co., Ltd. (www.fangshenmo.com) Shandong Texas, site construction materials leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. New material in Edison led the staff warmly welcome all inquiries negotiations to create new materials Edison a better future.
