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.

Does your sump pump have a cover? If not, it is highly likely that your pet is getting dirt and other contaminants in it, which can lead to clogs that will cause it to slow down or stop eventually.

This was the case of our client Mrs. Takla who lives in Saint-Jerome, and contacted us in order to replace her sump with one of the best sump pumps in the market ‘the TripleSafe’.

This sump pump system provides the ultimate protection against basement leaks and moisture problems.

It has three pumps that will respond to the most prevalent problems that a homeowner could experience when their waterproofing systems fail!

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.

Job Stories From Longueuil, QC
A poorly waterproofed basement in Longueil, Qc

Mrs. Takla contacted Systèmes Sous-Sol Québec because of a water infiltration in the basement of her house located on 356 Rue Saint-Sylvestre.

Following the 1.5 hour inspection of the owner’s basement, César Guevara showed Mina what was the waterproofing problem and how he could help fix it.

The water seeped in at the level of the wall as well as through certain critical areas of the concrete slab.

The team proceeded with the installation of an interior foundation drain system called WaterGuard. Next, they placed rock at the bottom of the hole, to lay the WaterGuard drain lengths there. Once they lay the“TripleSafe” pump system. This pump system then evacuates the water to the outside of the house. In order to finish the job properly, the team of technicians put concrete on the drain and around the pump system. In addition, a FlexiSpan membrane, specially designed to act as an elastic barrier, was applied to the basement walls to close the cracks, making it completely waterproof and dry.

Mina is now being able to use her dry basement properly and as she needed.

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!

J'aimerais donc obtenir un diagnostic et une soumission pour résoudre le problème.
