Laiwu Jinda tunnel dedicated tape composite waterproof sheet (1.5mm / 300 g), factory direct price Laiwu City of Geotechnical Materials Co., Ltd. is specialized in the production of acupuncture geotextile, PE, EVA geomembrane, HDPE, LDPE, EVA waterproof board, geomembrane, plastic single, two-way geogrid, steel grating, composite drainage network, tunnels, subways special composite waterproof board, PVC waterproofing membrane, TPO waterproofing membrane, polyethylene fiber, polyester waterproofing membrane, plastic blind ditch and other geotechnical waterproof material. Geomembrane composite made of impermeable geomembrane with a geotextile material. Geomembrane is mainly used for drainage and reinforcement. Geomembrane into a cloth membrane, two cloth one film, Dobb more films. Width 4-6m, weight 200-1500g / m physical and mechanical properties, tensile, tear, bursting and other indicators of high, geomembrane meet civil engineering needs irrigation, municipal, construction, transportation, subways, tunnels and so on. Since its selection of polymer materials and the production process added anti-aging agent. It can be used in unconventional temperature environment. Features: 1, geomembrane seepage collection, filtration and drainage effect in one. Along with isolation and reinforcement functions. 2. High geomembrane composite strength, peel strength, high puncture strength. 3, geomembrane friction coefficient, linear expansion coefficient. 4, geomembrane anti-aging performance, adapt to the environment temperature range, quality and stability. Applications composite waterproof board: 1, river bank, lake dam, tailings dam, water dam and reservoir area, channels, build liquid pool. 2, subways, basements and tunnels, tunnel impermeable lining. 3. The roadbed and other foundation saline seepage. 4, embankment, dam levels impervious blanket. Foundation vertical impermeable layer construction cofferdam, scrap yard. 5, seawater, freshwater farms. 6, road, highway, railway roadbed: expansive soil and loess of the waterproof layer. 7, roofing seepage.
