SL High pressure Injection packers for leak stoppage material

FeaturesHigh pressure injection packers for concrete crack repairs , waterproofing ,rehabilitation of concrete structures , basement leak sealing cracksealing etc.

Shenglong injection packer for injection machine spare parts is uesd with the Shenglong injection machine in concrete crack repair and water leaking stop. It suits for both polyurethane and epoxy injection.

Method of Construction for Injection

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

2.Drilling OperationDrill directly into crack section if the thickness of concrete is thinner than 10cm. For the thickness of 10cm~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 20cm~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 InstallationClean 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 OperationInject 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 OperationRemove 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 OperationRemove the water stopping material that is remained on the crack section. Spreading with the elastic sealing material.

Construction Notes

a. First, analysis cracks’ width and length,take cores to determine the development of crack depth.

b. If the surface is not easy dry, you can use torch drying, cracks due to moisture, can be found immediately to improve efficiency.

Crack Repair

 a. Injection should be started in elevation from bottom to top, when the foam materil emerge from the cracks should immediately stop,and start again after a while. In the infusion process, if the material adjacent to the needle position has been filled, you can jump without injection. If found cracks extension in both ends or cracks with cross, should drill holes again, re-grouting .

 b. To fill cracks with polyurethane, should grout again before the material become solid.
