    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.

    Water Infiltration problems in Saint-Anicet,Qc

    Mrs. Emannuelle, a client from St-Anicet, was having water infiltration problems that were damaging her entire basement area, even though she had already a pedestal sump pump installed in the basement. After contacting us, we have recommended the replacement of her old sump pump system with the new SuperSump pump since the old one was not efficient and was letting moisture come inside the house.

    Installation of a vapor barrier and a sump pump in a crawl space in Gatineau, Qc

    The problem Mr. Sirois noticed a high humidity in the house, cold air on the main floor coming from the floor and some places of the hardwood floor on the main floor was no longer at level. The cause was the humidity in the crawl space. He contacted Systèmes Sous-sol Québec to add a good vapor barrier membrane, clean the crawl space to improve air quality and reduce the humidity.   The solution Adding a SmartSump sump pump system, a drainage membrane and CleanSpace vapor barrier. Most of the moisture in the crawl space comes from the earthen floor that contains water and it can come also from the walls. The SmartSump will therefore be able to remove water from the ground outside and away from the foundation. The drainage membrane, on the other hand, is placed on the ground and makes it possible to drain the water that is on the surface towards the sump pump system. The CleanSpace coating which acts as a vapor barrier is placed over the drainage membrane and blocks moisture from the ground.

    Waterproofed basement in Gatineau, QC

    Our clients in Gatineau were suffering from water infiltration problems in their home's basement which caused humidity in the area and has also lead to severe coldness in the basement that has reached the whole house as well. As you can see in the first picture, the water has penetrated the floors and structural paint damages have occurred on the walls. Furthermore, our professionals have installed a WaterGuard system, our SuperSump sump pump, as well as our SaniDry and IceGuard systems and finished it with the EverLast wall restoration systems. Our clients are now very happy since they did not face any humidity problems again and can enjoy their new warm, dry and beautiful basement.
