2.Drilling Operation
Drill directly into crack section if the thickness of concrete is thinner than 10cm. For the thickness of 10~50cm, drill it with 45 degree angle by keeping a distance of 1/5 of concrete thickness. Make sure it penetrates the crack section. If the thickness is over than 50cm, keep the distance of 20~30cm and drill it with 45 degree angle until it penetrates crack section. And keep drilling by maintaining the fixed interval. (5 holes per 1 meter. Drill it in zigzags)​

5.Injection Operation,Polyurethane high-pressure injection
Inject the waterstopping material by using the high pressure device or grease gun. Maintain the initial injection pressure as around 40kg/cm and increase the pressure by each 10kg/cm gradually until the waterstopping material flows out from crack section. Water will come out from the crack section first and then waterstopping foaming agent and then water stopping liquid at last. If the waterstopping material that is not foamed comes from the crack section, then move to next packer for injection.​
