If the thickness is 10cm~50cm, perforate in the distance of 1/5 thickness of the concrete. ![]() If the concrete thickness is less than 10cm then directly perforate to fractured spot. If it is possible, then make position of perforation hole that contacts crack as thick as 1/2~2/3 of concrete thickness. Perforation angle between concrete surface and crack should keep 45 degree angle or under. External diameter of Drill Bit should be 10mm. During the perforation use hammer drill and make holes with same diameter. Normally when injecting polyurethane foam, it is injected through packer generally. Prepare around leaking and fracturing spot and fixate packer.
