WATERROOF:●Construction?joint●Pipeline and concrete iron in wall or cement board●Surrounding the concrete iron or joint●Inner joint of cableFIX:●Preventive injection hose: type LWRI, I and II●Cross section of water stop Procedure Base surface?must be sound, clean, dry,?no oil?or?dust?ect. Clean all practical, demolding agent, bleeding cement, old coating film and other loose animals.Construction Conditions?Base surf. Temp. ? ? ? Min+5℃ Max.+35℃ Environment?Temp. ? ? ?Min+5℃ Max.+35℃Base surf. humidity????Dry and no visible waterTools?■Applied for fixing water stop or placing injection hose. Apply the sealant on base surface, if base surface is not flat, nozzle?size need to be changed. Fix water stop and injection hose to the sealant. Concreting 2 hours after sealant solidify . ■Applied for sealing of the construction joint If the triangle nozzle?is used, refer to the following instruction:Building ThicknessSize of the triangular sectionLength of the extrusion?600 ml/bar (theory data)Length of the extrusion?320?ml/bar (theory data)<30cm15mm6.2m3.1m30-50cm20mm3.6m1.8mActual length of extruded sealant may be shorter because of condition difference. ■?Apply the sealant flat in the middle of concrete section. Concrete edge: 10cm (reinforced concrete ) or 15cm (non reinforced concrete
