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) Concrete height: ＜50cm------- Solidifying time :2-3 hours Concrete height: >50cm-------- Solidifying time :2 days Press the sealant tightly during concreting to avoid cellular holes. Clean Tools clean all the tools and equipment when process finishedConditionsLW swell sealant will expand some hours after water contact. It is not allowed to stay a long time in water (water draining complete in 24 hours) before concreting. Placing  the sealant in movable crack is not allowed. When water level rise, the sealant expand and sealed the crack. In drying condition, the sealant shrinks to original size; but will re-expand when touching water. Suggest to apply the sealant under less than 2 bar pressure  (test pressure is 5 bar) because of sealing width limit. If the pressure is high than 2 bar, the sealant can be used to fix the injection hose.StandardDB11/581-2008Shelf time12 months  (sealed packing, Temp. +5℃---+25℃, drying condition)Package600 ml/bar (20 branch/box) 320 ml/bar (24 teams/box)
