Systèmes Sous-sol Québec Before & After
  • Encapsulation of a crawlspace in Montreal

    Encapsulation of a crawlspace in Montreal

    Mr. Robert contacted us because he needed help with moisture problems in his crawlspace. Upon arriving at the free inspection, we found that the best solution was to encapsulate his crawlspace with the CleanSpace vapor barrier. To start, our team removed the debris from the crawlspace. They then installed the drainage mat, followed by the CleanSpace vapor barrier. Finally, they installed a SaniDry Sedona dehumidifier and a SmartDrain drain system to ensure good humidity and prevent flooding.

    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.

    Insulation of crawl space discovered in Godmanchester, Qc

    PROBLEM 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.    SOLUTION  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.
