Before and After Pictures from Gatineau
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.

This client had cracks repaired in one wall of his block foundation, but had not repaired all of the walls. Over time, one of the walls will start to arch and tilt inward from the basement. If nothing will be done, the situation will only get worse. So, he contacted Systèmes sous-sol Québec in order to stabilize his wall once and for all!

Job Stories From Gatineau, QC
A super humid crawl space in Gatineau, Qc

Mrs. Forster recently purchased a property located in Gatineau, and has discovered problems with dampness along with musty smell in the house. In winter the main floor is very cold. She contacted Systèmes Sous-sol Qc to obtain a free inspection and find out the costs of insulating her crawl space.

To solve her problem, our team encapsulated her crawl space with our CleanSpace drainage membrane and liner, and insulated the foundation walls with our SilverGlo panels. With this solution, our client will be able to have a comfortable home.

Water in a basement in Gatineau, Qc

Mr. Sirois has lived in his house for 1 year. The house was humid and he felt cold air on the main floor coming from the floor.

In some places the hardwood floor on the main floor was no longer level.

The problem? Of course the humidity that was in the crawl space. He contacted Systèmes Sous-sol Québec to add a good vapor barrier membrane and clean the crawl space to improve air quality and reduce humidity.

Our solution was the addition of a SmartSump sump pump system and the addition of a drainage membrane and CleanSpace vapor barrier. Most of the moisture in the crawl space comes from the earthen floor which contains water and 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.

With this solution, Mr. Sirois will be able to have a much drier and healthier crawl space. This improves the air quality, but for more efficiency it would also be better to add a dehumidifier like the Sanidry Sedona.

Bonjour, de l'eau se retrouve dans une place précise dans le milieu du sous-sol à tous les printemps. Aucun signe de fissure de la fondation et aucun signe d infiltration au bas des murs. Je sais que le béton a été mal coulé lors de la construction de la maison en 1990...pente descendante vers le milieu du sous-sol qui est probablement impliquée dans la cause. Merci pour votre retour.

Bonjour, j'ai 3 projets pour ma maison aquis en 2021. Maison contruite il y a longtemps et le premier propriétaire a voulu agrandir le vide sanitaire.

Pour finir, j'ai un abri d'auto. En bas des poteaux (3), ils ont mis une boite en bois en dessous de chaque pour cacher le bas du poteau et le ciment. Par contre, le bois s'éffrite. J'aimerais enlever ce bois Merci
