When you have a sump pump that does not have a lid, it is highly likely that your pit is getting dirt and other contaminants in it, which can lead to clogs that will cause it to slow down or stop eventually.

So when we came to check this sump pump in Longueil, we knew right away that it needs to be replaced by a new one.

Our TripleSafe sump pump comes with a three-pump system that adjusts automatically to meet pumping requirements, in addition to a battery-powered pump to protect the place from flooding during power outages.

Ms. Perreault had a very wet crawl space that was not isolated. The humidity was felt all over the house so she was worried about the quality of the air in her home. She decided to call Systèmes Sous-sol Québec in order to solve her problems once and for all.

 

At start, our specialists installed our EZ Flow drainage system which was connected to our SuperSump sump pump system. This way, the water is directed down the drain and discharged by the sump pump. Then, in order to eliminate the humidity, our drainage membrane as well as our CleanSpace coating was installed. The membrane, among other things, allows surface water to flow into the sump pump system and create a thermal cushion. Our CleanSpace serves to insulate the house from the earthen floor and lock in moisture. It also gives a clear and clean appearance to the crawl space.

Brick blocks and columns do not provide effective and permanent support for the crawl space, as they will move according to the weak ground motions.

So we must put pillars that support the house on stronger soil.

We have stabilized this crawl space in Longueuil by adapting one of our simple solutions from which SmartJack pillars and galvanized steel PowerBrace beams that will lift the foundation to their original position immediately.

Job Stories From Longueuil, QC
Humidity in a crawl space in Longueuil, Qc

Ms. Perreault has lived in her house for several years. Since 2015, she has had humidity problems and was worried about the quality of the air in her home. She even had up to 3”of water in her crawl space.

So she received quotes from many contractors, but she chose to do business with Systèmes Sous-sol Québec for the reliability and performance of the proposed solutions.

The solution was to first install our EZ Flow drainage system which was connected to our SuperSump sump pump system. This way, the water is directed into the drain and is evacuated by the sump pump. Then, in order to eliminate the humidity, our drainage membrane as well as our CleanSpace coating were installed. The membrane, among other things, allows surface water to flow into the sump pump system and creates a thermal cushion. Our CleanSpace insulates the house from the earthen floor and locks in moisture. It also gives a clear and clean appearance to the crawl space.

With this solution, Mme Perreaut has a permanently dry crawl space!

Work Requests From Longueuil, QC
Project Location: Longueuil, QC
Nous aimerions faire egaliser le sol du vide, ajouter des poteaux de soutien et faire isoler le vide sanitaire. Merci
Project Location: Longueuil, QC
Taux d'humidité élevé dans le sous sol (58-63%), ouverture de mur démontre haut taux d'humité sur la lice de 2x4 sur la dalle de béton, pas de moissisures generalisées mais odeur d'humité, une zone semble montrer infiltration ou percolation plus importante avec présense de moisisures sur la dale sous le coupe vapeur d'un plancher d'ingénérie. Colombages sains mais trop humides, Taux d'humité baisse dans le bois en montant sur le mur. Isolant sain, par vapeur efficace, gypse sain/taux humidité ok. Inspection de drain Francois par caméra, 50% visible, démontre mauvais niveaux (ventre de boeuf), zone mal drainée alignée avec section intérieur présentant signe d'infiltration/accumulation d'humidité. autre 50% drain Francois par visible car écrasé a 6pi du point d'accès. Inspection faite par caméra via regards sous-sol car pas de cheminée d'accès exterieure. Le drain Francais ne semble pas fonctionnel, le Ptrap est vide. Aimerais avoir une évaluation de la situation et proposition de solutions. Merci

It's regarding a pre-purchase inspection and the inspector has noted a significant amount of efflorescence on the basement under the floor and can potentially increase moisture problem. My clients are wondering how much it would cost to remove such/problem and how can this be fixed. Therefore they are inquiring a trusted expert to give an estimation and do the work once they proceed with the property. Thank you

Bonjour Nous avons déposé une offre d'achat qui a été accepté par le propriétaire. L'inspecteur nous recommande de faire une inspection du vide sanitaire avant la signature finale. La locataire nous parle d'odeur d'égout dans son appartement pendant l'été. Nous avons aussi remarqué de la moisissure en surface et de la corrosion à l'entrée du vide sanitaire. Nous avons besoin d'une expertise très rapidement si possible le 20 où le 21 avril.
