Cracked Foundation Wall in Cornwall, Ontario

This client contacted us initially to fix his humidity problem in his crawlspace, but while we were there, we noticed that there was a very large crack in the foundation wall of the crawl space.

We fixed this issue by installing the PowerBrace system. It consists of zinc coated beams and components. PowerBraces utilize a joist reinforcement that distributes the load evenly. The crawl space is now stable and sealed.

Waterproofing a wet basement in South Lancaster, QC

Here is another wet basement that has been waterproofed in South Lancaster.

When our client Joy found our website, she knew that we can fix her basement problems, without taking too much time.

So we installed a complete waterproofing system including 25 feet of WaterGuard interior drain to intercept water coming in, a TripleSafe sump pump system with three pump system for more protection, and finally our SaniDry Sedona dehumidification system which is the best in the market.


Encapsulation and waterproofing of a crawl space in Godmanchester, Qc

Insulation of crawl space discovered in Godmanchester, Qc


Mr. Bruno's crawl space was uncovered and created humidity in the rest of the house. The client did not want this to affect his family's health in the long term.



 Systèmes Sous-sol Québec’s team suggested a solution that guaranteed a dry space all year round. A solution including 3 products; TerraBlock insulation, SmartDrain and CleanSpace encapsulation product.

Our TerraBlock insulation provides a puncture-resistant vapor barrier on all surfaces it covers - one that will not be damaged by water or support the growth of mold, rot, and mildew.

As for the SmartDrain, it is a floor drain installed at the lowest point of the crawl space to intercept water infiltration caused by plumbing leaks.

And finally the CleanSpace will prevent the growth of mold. In addition it is odorless and very safe to use.


Replacing an old sump pump in Godmanchester, Qc


Mrs. Quesnel suffered from water damage in her basement because her sump pump stopped working.


Replacing her sump pump system with our TripleSafe. The TripleSafe includes 3 pumps, one of which is battery operated in case of a power failure. It's our most efficient sump pump system and gives you the peace of mind. We connected our Sanidry Sedona dehumidifier to it to control the level of humidity in the basement.
