Sika Japan showcased their SK Grout Plug A construction method for repairing cracks in concrete structures at the Architectural Restoration Expo 2023. With rainwater or air intruding into reinforced concrete, the rebars inside corrode and weaken the structure. This construction method prevents corrosion from decreasing structural strength. The injection device is attached to the actual wall, with a pressure gauge to temporarily seal it. Once the temporary sealant has hardened, epoxy resin is sucked up into the injection pump using this type of injection pump. SK Grout Plug A is then injected into the crack, compressing the air in the pressure tank with resin entering, using a check valve for construction. With cracks in reinforced concrete being inevitable, Sika Japan’s SK Grout method is an effective solution for repairs.Generated by OpenAI
