Job Stories From Oshawa, ON
Oshawa, ON Foundation Crack Repaired with FlexiSpan

Stephen D. of Oshawa, ON noticed that his foundation wall was showing signs of water seepage, manifested in the form of a lengthy wall crack. Worried for the healthfulness of his home, he sought out assistance in fixing this problem, which led him to the talented team at Clarke Basement Systems.


Claude Mathieu met Stephen at his residence to analyze the problem and determine what the best course of action for remediation would be. Claude recommended the FlexiSpan waterproofing system, designed specifically to fix leaks in foundation walls. Primary Foreman Lucio Flores arrived with his crew to perform installation, which took only a single day and required minimal intrusion into the home. Stephen was ecstatic about the finished project, and greatly appreciated the peace of mind that his foundation would remain leak free.

I am looking for a quote to inject epoxy or urethane into a hairline crack in my interior poured concrete basement wall. It is a short wall that is 31 1/2 inches (both the crack and the wall). This is my house and I am not selling. The wall has been cleared of all studs etc and is ready to go. Thanks ..Wayne

The basement walls are fine, no signs of bowing or damage, however there is a crack in the wall that leaked during heavy periods of rain. We've redirected the downspouts away from the crack and haven't seen any further leaking. We're looking into having the crack filled and repaired.
