Hydrophilic Urethane Grout?is a kind of rapid and high efficiency chemical grout material?used for seepage-proofing and leaking stoppage. It has unique sealing effect for a great quantity water burst and leaking in variety of projects,Website:http://www.long-wee.com, which has been applied widely in plenty of projects. The mentioned achievement has ever won National Process Awards in Science and Technology. Characteristic: ●Good hydrophily. Wate is not only a thinner, but also a curing agent. Grouting disperses and emulsify firstly after meeting water then gels.●Can be grouted under moist and water burst case, strong adaptability to water. Can solidify in seawater and water with ph value 3-13.●Nontoxic.●Convenient operation,no complex mix.●The gel is elastic and can swell after meeting water.It can be applied to water proof treatment of deformation joint.It has double function of elasticity?water stop and stop water by water.●Can be mixed used with HW hydrophilic polyurethane chemical grouting material at any ratio to get the material with various intensity and swelling ratio.Main data: ? ? ?Item index （25℃,mPa.s）viscosity 150－350（min）gel timeGrout : water＝1﹕10≤3（％）swelling ratio≥100strength?of viscosity

?It is mainly applied to treatment of basic seepage-proofing in concrete expansion joint, crack, construction joint of water conservation water and electricity, tunnel, subway, civil defence, metallurgical engineering, industrial and civil architecture ect.. Precession:
1. Check the part of leaking and clean up the dirt of surface. 2. Drill the hole near the part of leaking. The slant hole can be drilled through the crack if the crack is deep. The width of two holes is different according to the width of crack. Normally it is 20-50cm.The crack is narrow the width is small. If wide then big. 3. Bury the grouting hose (box) with quick speed cement or epoxy, polyurethane adhesive.. 4.?S
