Grouting a highly elastic material, Introduction of high resilience polyurethane grouting material is plugging years isocyanate and polyol poly, 2 Features (1) hydrophilic, and produce water immediately after polymerization, emulsion dispersion or foaming swell and stick into the soil with sand elastic solid stick form a consolidated body, quickly plugging cracks colored polyurethane waterproof coating, permanent seal. (2) can control the induction time, after consolidation time water can be controlled in more than 10 seconds to a few minutes. (3) the expansion of the great, good toughness, no shrinkage, strong bond with the substrate, the water quality of adaptability. (4) can be irrigated, and can remain at low temperatures and grouting use. (5) The construction is simple. Water test: After the film is completed inspection method using water, love the door with mortar made dams, to leak around the block with high polyurethane waterproof coating material type, and then turn on the water polyurethane waterproof coating, the most shallow water of not less than 20mm, water time of 24 hours, check for leaks. Quality inspection: coating materials must meet the design standards and specifications, brushing coating method, lap, close head shall comply with polyurethane waterproof coating series, the end of the film should be firmly bonded coating tight seams tight, no damage, hollowing. Waterproof layer should be brushing uniform, firm bond with the grass roots, smooth surface, not a flowing, wrinkles, bubbling, Lucy and Alice carcass defects. Polyurethane waterproof coating plant, Beijing polyurethane waterproof coating, long a source of waterproof material provided by the Weifang City for the source of waterproof material Limited. Weifang City for the source of waterproof material Ltd. (www.jiuyuanfangshui.com) strong, credible, Shandong Weifang waterproof, moisture-proof materials industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the long-source waterproof material into the brilliant and you work for a better future!
