Systèmes Sous-sol Québec is proud to have Trudeaux as part of the production team. 

Before and after photos from jobs I've worked on:
  • Insulated and encapsulated crawl space in Baie-d'Urfé
    Insulated and encapsulated crawl space in Baie-d'Urfé

    In 2015, a client located in Baie-d'Urfé did business with us to install the TripleSafe sump pump system and to finish the basement with finishing products specially designed for basements.

    Three years later, our satisfied customer contacted us again because she was now ready to carry out a crawl space insulation and encapsulation project.

    Our specialist, therefore, recommended the installation of SilverGlo insulation panels, which are insulation panels made of graphite particles that increase the value of thermal resistance. This insulation is also covered with a radiant barrier to reflect and preserve the heat towards the interior.

    The floor has been encapsulated with the CleanSpace vapor barrier membrane, which is a 7-layer expanded polyethylene coating containing an antibacterial additive to block the growth of mold. This membrane blocks the vapors of water that evaporates into the air and redirects them to a well. We are the experts in crawl space insulation and encapsulation and our products are the most effective for your basement space.

    If, like this client, you want to solve your problem once and for all, do not hesitate to contact us!

  • Foundation support in Lachute, Qc
    Foundation support in Lachute, Qc

    Our customer’s foundation in Lachute was curving, which is a serious problem and sign of failure in the basement foundation walls.

    We have solved this problem, by installing PowerBrace galvanized steel beams and several smartJacks.

    The beams form a system designed specifically to support the walls of failed foundations and to straighten the walls to their original position over time. Zinc coated, the PowerBrace system resists erosion, reduces abrasion and makes beams non-toxic

    As for the SmartJack  Support Pillars , those are steel support systems used to stabilized and level the girders and floor joists in a crawl space.

    In Addition they are super strong (support loads of more than 60,000 lbs.), and is the only solution that addresses problem soils.

    Our patented system stands out from the others and we are very happy to have had the chance to install it at our customer’s place to solve his problem once and for all!


  • A wet crawl space in Côte Saint-Luc
    A wet crawl space in Côte Saint-Luc

    This Côte-Saint-Luc customer needed an assessment from our company for a mold-to-crawl problem. When you see traces of mold in the crawl space, this is a sign that you need to dehumidify the space efficiently and permanently. As the crawl space is a space built in a hole in the ground, the water pressurizes and infiltrates through the ground and pores of the concrete.

    Our waterproofing solutions solve these problems at the source. The CleanSpace drainage mat and vapor barrier membrane are installed on the floor to prevent water vapor from escaping into the air. We install on the walls the SilverGlo insulation which is an insulation board composed of graphite particles and which is covered with a radiant barrier to preserve the heat inside. It is a product that saves you a lot of energy consumption. Finally, the SaniDry dehumidifier keeps the space at an optimal relative humidity level. It is a system that empties automatically through a water drain pipe.

  • SuperSump sump pump in Saint-Mathias-sur-Richelieu

    Very often, people suffer from water infiltration but wait several years before recognizing the problem and wanting to solve it.

    Fortunately, Systèmes Sous-sol Québec is solving the problems of water infiltration at its source, because we are the experts in all that is underground.

    We have easily solved the problem of water in this house, through the installation of a sump pump system. The choice of a system must be made correctly.

    It is not enough to dig a hole and throw a pump. Among other things, the system must have an airtight cover so that infected water vapors do not come out of the system.

    The pump must be installed on a raised support so that the sediments in the water do not diminish the performance of the pump.

    In addition, the cover must serve as a floor drain that allows water to enter in the event of a plumbing leak, but must not allow the water vapor or water to exit through this hole.

    Our system is very powerful and contains all these features that make SuperSump the best sump pump coating.

    One of the citizens of Saint-Mathias-sur-Richelieu called us asking about our sump pumps since she learned from her friend that we have the best products in the market. Mrs. Dion needed a sump pump that does not fail, nor clogs especially during flood season.

    Furthermore, our specialist recommended the installation of our SuperSump pump.

    Our SuperSump is a complete sump pump unit that has a powerful 1/3 hop cast iron pump within a polyethylene superliner sump liner. It also resists clogging and can pump solids of 12.5 mm diameter.

  • Encapsulating a crawl space in Mascouche, Qc
    Encapsulating a crawl space in Mascouche, Qc

    We have transformed this crawl space in Mascouche into a very beautiful area.

    The soil was very wet, mold and insects were growing. So we installed our CleanSpace membrane to insulate the house from the ground and our company’s SmartDrain that intercepts water infiltration caused by plumbing leaks.
