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.

Vicinity of Jarvis Street in Oshawa
I have a very old house; it was built in 1927. The basement has always leaked. At least since I pulled up the sub-floor put down by the previous owner. In the past year, the walls and ceiling have started to really crack. There is a soft spot in my living room floor and the ceiling in the living room is beginning to sag. The wall at the top of my staircase seems to be bowing out and the plaster is severely cracked
