Many homeowners in Saint-Constant suffer from Foundation cracks in their houses. Patching repairs are not always the best solution.

We opted to install SmartJack poles in order to stabilize the floors, and a vapor barrier to drain the water to the inner drain and have a permanent solution.

ThermalDry waterproofing membrane does not only stop humidity from dissipating into the basement but also could lead any water infiltration down to the WaterGuard. ThermalDry also reflects the heat back into the basement.

Many residents in Quebec suffer from water infiltration into their basements and our client in Saint-Constant find out that his existing sump pump was not working properly and the open sump which allowed all the moisture to rise in his basement.

Our team has installed our powerful sump system, the SuperSump, which is equipped with the best features such as a fully sealed sump, holes in the sump to drain water from the ground, a cast iron pump that performs best as well as an alarm that would sound if the water level rose too high in the sump.

Ms. Nadia had moved into this house last year and from the start she had problems with water infiltration. Yet she had bought a property that already had a sump pump. So she thought her basement was protected and waterproofed.

Mrs. Nadia did several researches to realize that there were several solutions and models of pump and she decided to contact us for good a advice.

 Our certified waterproofing specialist has completed his full assessment, lasting nearly 2 hours, making sure nothing is missing as the cause of this water entry. He agreed that there was regular water infiltration and that installing a new pump would be the solution to the problem. We recommended the SuperSump pump, which can evacuate 8,300 liters of water per hour. The basement has remained dry ever since.

Job Stories From Saint-constant, QC
Installation of a pump in Saint-Constant, Qc

Our client Ms. Nadia had just purchased this property about a year ago. It was a 1984 construction and this house already had a pump. It is therefore believed to be protected in case there was a flood or water infiltration. Water infiltration was even worst during the spring thaw. She was in constant trouble and was well aware that her basement was not as well waterproofed as she thought. Ms. Nadia did her research and decided to give us a call for a free quote.


The sump pump is the heart of any drainage system in a home. Having a pump that works well and efficiently is essential. If not, your basement could be flooded. There are several elements that come into consideration when it comes to choosing the model. Our team is certified in waterproofing and will be able to guide you to the best solution. In this case, our client Ms. Nadia chose the SuperSump model. She can now feel confident that her basement is waterproofed and will stay dry, in her home in Saint-Constant, Qc.

Waterproofing a basement in Saint-Constant, QC


Our client in Saint-Constant wanted to finish his basement. During his inspection of the state of the basement, he found traces of water and some damages to the floors, walls and some furniture he had stored in there. 

His insurance company asked him to repair the source of the problem before they could let him finish the basement at their expense. His search for a reliable company to do the work led him to us.

Our specialist Jorge  inspected the basement, inside and out, and explained to the client what was causing the water seepage. By identifying the client's needs and budget, Jorge was able to recommend the best solution.



Jorge recommended a partial WaterGuard internal drain. In contrast to a French Drain, the WaterGuard does not have to be installed around the full perimeter, even though this is the mostly recommended solution. Our client had a limited budget and Jorge worked within his budget to install the internal drain where it was needed.

He also recommended connecting the drain to the exisitng sump pump to stay within budget. Our foreman Michel did the installation exactly as per Jorge's plan and connected the drain to the pump.

Our client was happy to be able to have a dry basement and get the money from his insurance company to do the work.

After many years of suffering due to the infiltration of water in the basement, Mr.Ruslan wanted to find a permanent solution. With a very high level of humidity in the basement, it also smelled musty all the time.

Every time there was rain, water was seeping into the basement, and during the last water infiltration, our client had enough.

The owner wanted to finish his basement once and for all, and for this reason, he wanted to have a permanent solution to regulate the infiltration of water.

Our team chooses to install a Waterguard system throughout the interior perimeter of the house. This sole drain takes the water from the walls and joints of the foundation, which was perfect for this basement.

The installation was completed very quickly within only a few days and the customer paid less than twice the costs he received in the submissions to install a French drain system!
