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.

Leveling concrete porch. Water pooling and seepage into basement with heavy rain/snow.

Hi, we are looking to get a quote to repair a foundation crack. I've only seen it leak during a rain storm with high winds, but I'm sure there are other times it has leaked as well. There are also holes in the wall from where the electrical connection comes in and from an old panel. We are also looking to replace the window and frame, but are unsure if it would be better to do it before or after the foundation crack repair.
