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
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.

Rue Cousineau in Laval
Nous avons acheté une maison le printemps dernier, APRÈS la fonte de neige et de glace. Toutefois, avec le redoux des derniers jours, nous avons eu une infiltration d'eau sur une petite partie dans notre sous-sol. Comme la maison nous a été vendue avec garantie légale et que ce problème était déclaré comme réglé, il est maintenant considéré comme inconnu et pourrait être potentiellement un vice-caché. J'aimerais savoir si c'est possible d'obtenir l'avis d'un expert qui pourrait trouver la cause du problème. L'expert devra aussi juger si cela pourrait s'apparenter à un vice caché et être en mesure d'estimer les coûts d'une éventuelle réparation. Merci de votre aide.

Water leaks in the basement when temperature is mild like today. Due probably to water/snow accumulation around the outside of house.
Rue Fred-Barry in Laval
For the second time in 15 days I can see water entering in our basement, in the same spot. Not a lot of water, but looks like that everytime that the temperature goes up the issue comes back. I would like to check it as soon as possible. Thank you.

Hi, I speak french also, I have a concrete cold room under my concrete balcony that water comes in from walls and the bottom. Is there anyway this can be fixed without a french drain from the outside. It has been injected once by the old owner over 10 years ago but it has been leaking from when i purchased the home 10 years ago. Merci Pietro

Réparations d un fissure dans le sous sol (non aménagé) qui cause infiltration d'eau
Rue Sicotte in Laval
Bonjour, nous avons eu de l'infiltration d'eau à l'automne au niveau de la dalle de béton du sous-sol et au niveau de la base d'un des murs de fondation. Mes assurances prévoit une fouille exploratoire au printemps pour inspecter l'état du drain français (datant de 1979). Nous prévoyons qu'il sera rendu à un état où il faut le remplacer. Je cherche donc une entreprise pouvant effectuer les tâches suivantes: excavation autour de la maison (incluant des espaces restreints, présence d'arbre à proximité, etc.), remplacement du drain français, installation de cheminée et de margelles vis-à-vis les fenêtres du sous-sol, correction de la pente du sol sur la largeur arrière de la maison. C'est un dossier pris en main par mes assurances, je n'ai donc pas le contrôle sur l'entrepreneur qui fera la fouille exploratoire, mais je l'ai sur l'entrepreneur qui effectuera le reste des travaux par la suite. J'aimerais donc obtenir une soumission (visite des lieux nécessaire) et obtenir plus d'informations sur les façons de financer ces travaux également. Merci beaucoup.
Rue Simoneau in Laval
Bonjour, J'ai remarqué la semaine passée qu'il existe de l'eau sous le parquet de mon sous sol lorsque la température a baissée. En regardant de l'extérieur de la maison, j'ai constate qu'il y une fissure dans sur le coin de la bâtisse. Pouvez-vous SVP envoyer un expert pour l'examiner et me donner une soumission pour la réparation? Merci et bonne journée Chafic

Some water in the basement at the base of the external wall. Hardwood damaged. Obvious that this was not a one-time incident.
