Method of Construction for Injection


1.Crack and leakage condition inspection
Check the process procedure after finding the thickness, width and depth of crack and leakage condition of the structure


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)


3.Packer Installation
Clean the inside of drilled holes with compressor. Make sure that rubber sleeve of packer and cutting line of tightening nut should be put into the inside of concrete surface when installing. Tighten the packer completely by using the T-box. (Packer might be damaged if you tighten it too strongly)


4.Injection Operation
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.


5.Packer Removing Operation
Remove and break the packer by using vise pliers or hammer as a tool. If there is still a wet section, then inject the water stopping material again.


6.Finishing Operation
Remove the water stopping material that is remained on the crack section. Spreading with the elastic sealing material.
