A clean crawl space in Sainte-Dorothee

Whenever we work on the waterproofing and encapsulation of a crawl space, we are happy to see how this space is transformed from an earthen place with moist air into a dry, clean and bright space that can be used for useful purposes. This adds more usable space to your home and increases its value. Not only can you use it to store your seasonal items, but the air becomes dry and of better quality because the CleanSpace vapor barrier membrane contains an antibacterial additive that prevents the formation and proliferation of bacteria and molds and blocks water vapor. Thus, the air that moves from your crawl space to the upper floors is healthy for your health. We are happy to have completed another crawl space encapsulation project in Sainte-Dorothée!

Job Stories From Laval, QC
Insulate the walls of a basement with Foamax in Laval, Qc

Mr. Demuy has an uninsulated basement under his garage with concrete walls and floors. He wanted to turn this space into a storage place, but he feared the humidity that was there and seeked to insulate his walls from his basement. He contacted Systèmes Sous-sol Québec in order to have a reliable and efficient solution.


To insulate the walls of his basement, our experts installed our Foamax insulating panels. They are made of high performance polyisocyanurate foam coated with a white finish on one side and a vapor barrier on the back. They provide comfort, superior insulation and make walls appear cleaner and brighter.


The walls of his basement are now insulated and Mr. Demuy will be able to finish the work and use his new storage space.

Dampness in a crawl space in Laval, Qc

Mrs. Dube contacted us to have an inspection on her crawl space since she never goes in there and is uncertain of the situation.

Our specialist Jerry went out there to find a large amount of mold and high humidity. Following our client’s approval, we encapsulated this crawl space by installing our CleanSpace vapor barrier that will prevent moisture by separating the house from the ground. An antimicrobial ingredient is also present in the vapor barrier to prevent bacteria from reproducing.

Underneath it we have also installed our drainage mat that will allow water to flow to the sump pump.

 After the installation, Mrs. Dube reached out for us to tell us how happy she was with our work!

Basement Waterproofing in Saint-Jean-Chrysostome, QC

Our Clients noticed that water was coming through the walls in their home's basement. In order to ensure that this water infiltration would not lead to a more serious problem, our clients decided to search on the Internet for a company and found Systèmes Sous-sol Québec, a company located in Laval, which specializes in basement waterproofing.

Following their call, our company sent one of our specialists in water infiltration, Eugene Alexeenco, to inspect their basement. Eugene advised them to install a WaterGuard interior drainage system to prevent water from seeping in through the walls of our client's residence, a CleanSpace Wall membrane, a Supersump sump pump system, and an Iceguard system.

Our client’s problem is now resolved. There is no more water infiltrating their basement and they can now have the peace of mind and benefit from this large living space.

Work Requests From Laval, QC
Project Location: Laval, QC
J,ai une grosse fissure ,m'inquiète bcp .je vis dans l'insécurité avec ma famille. Besoin d'une réponse très urgent .Merci infiniment
Project Location: Laval, QC
Suite à une grande pluie la semaine dernière, une flaque d'eau s'est formé au milieu de ma salle familiale au sous-sol. Il ne semble pas y avoir de fuite, l'eau semble entrer par la dalle. Pour remédier à ce problème et éviter que ça se reproduise, je pense que l'installation d'une pompe à puisard est pertinente. J'aimerais: 1. Savoir que c'est bel et bien le cas. 2. Connaître votre prix pour l'installation complète. Merci,

"Joint froid" entre la fondation originale de la maison et la fondation d'une extension qui a été construite plusieurs années plus tard. On a l'impression que ce joint s'élargit au fil des ans. L'eau pénètre de façon abondante lors de fortes pluies et au printemps lors de la fonte des neiges.

Bonjour, Je dispose actuellement d'une pompe de puisard << standard >> qui est électrique. En cas de panne électrique, je désire ajouter une pompe de secours à batterie. Dans cet ordre d'idées, je suis curieux de connaître vos produits (TripeSafe, SuperSump et SmartSump). Quel serait le meilleur produit pour répondre à mon besoin? Bien attendu, quel est le coût d'installation? Bref, est-il possible de prendre un rendez-vous avec l'un de vos conseillers? Merci,
