Concrete often cracks. It is inevitably recognized and experienced. Concrete construction requires construction joints and cold joints. All of these unwanted openings in concrete structures may cause very serious problems leakage.
Most of these problems can be economically solved by utilizing the High Pressure Injection Systems.
STEP 1: Clean Surface
Sometimes the concrete surface is hidden under a surface of mineral deposits left from long-term water leakage.
STEP 2: Drill Injection Holes
In order to inject the resin into the crack, it is necessary to install injection ports, also called mechanical packers.
The depth of the drill hole intersecting the crack should be somewhere close to the center of structure, if possible.
STEP 3: Insert Injection Packers
Place packers in the previously drilled hole, so that the top of the rubber sleeve is below the concrete surface. If the packer can't be pushed into the hole, tap it in. Tighten the packer with a wrench as tight as necessary.
STEP 4: Flush Crack If Necessary
In some circumstances, it can be very useful to flush the crack with water to improve the subsequent penetration of the injection resin into thicker walls.
STEP 5: Crack Injection
Choose the proper resin for the correct application. The nature of the crack / joint and the conditions at the job site determine the choice of material.
