Concrete Sinking Before Building is Even Finished in Toronto, Ontario

There’s a lot that goes into building a home. It’s a huge undertaking, so when things go wrong, it can be a significant setback. 

In Toronto, Ontario, a custom home builder was working on a home when he noticed something going wrong. The concrete back patio he had poured six months earlier was already starting to sink. The house wasn’t even through the building stage yet, so he knew he needed a long-term fix.

The builder reached out to Canadian Concrete Leveling and met with Project Manager Paul Mendell. He explained to Paul what happened and that he was surprised the concrete failed so quickly. Paul explained how and why concrete sinks and played a demonstration video of our PolyLevel® System. Bad fill material allowed a gap to form, causing the slab to sink. Our solution not only lifts the concrete but also compresses fill soils below. The customer was delighted to hear about such a unique solution and looked forward to seeing it for himself.

Foreman Kyle McKeown drilled several dime-sized holes in the concrete slab to inject our PolyLevel® System. As the high-density polyurethane is injected, it expands, lifting the slab and stabilizing substrates below. 

The home builder couldn’t believe his eyes as he watched the concrete lift back to an even grade. He’s glad he didn’t need to repour the slab and knows who to call if he ever runs into this issue again.
