A crack in a poured concrete wall is typically caused by concrete shrinkage due to the concrete setting for years after the wall is initially poured. Other factors that can worsen the cracking and separation would be foundation settling and soil expansion. For these reasons, a solution is needed that will permanently repair the crack, even during further wall movement.
A whole market of injection sealants has arisen to repair the wall cracks, but due to further shrinkage and wall movement, these repairs will eventually fail. So, if your only repair solution is just the injection, then the crack will eventually become larger and continue to leak. American Basement Solutions has found a solution that will repair the crack permanently.
First, the crack is sealed with a flexible sealant on the surface of the crack from top to bottom. In many cases, this sealant will slow, if not stop the flow of water through the crack. Second, a waterproofing panel system is fastened to the wall over the sealant, and tucked into our AmeriGuard waterproofing system or drainage created at the floor. The outside edges of the panel are sealed to the basement wall to ensure any wall seepage will drain into the drainage system below the floor.
