If you have a vented crawl space, especially in a humid climate, it most likely has moisture problems.

Moisture might come from several sources, such as uncovered soil, foundation walls, foundation vents and more.

Encapsulating your crawl space with quality products engineered for this space is the best way to keep it dry and clean.

You can see in these pictures one of our crawl space encapsulation projects in Montreal-Ouest!

Sump pump systems will evacuate water before it seeps into the basement and causes flooding and damage. All the water intercepted is evacuated far from the house.

Our SuperSump pump system is a full-featured system that includes the best components available.

It has a superliner: the liner's airtight lid keeps out pests and debris, while also eliminating the safety hazard of an open sump pit. The WaterWatch alarm will ring when the water rises above the operating range of the pumps to warn you of a potential problem. 

In addition, it is equipped with a powerful, top-quality Zoeller sump pump.

Job Stories From Montreal-ouest, QC
Moisture in a crawl space in Montreal-Ouest

Our client in Montreal-Ouest was suffering from her wet crawl space.

Moisture was coming from the ground outside her house by migrating through the foundation walls. Since vented crawl spaces rarely get any kind of damp-proofing, wet soil outside the crawl space can come all over.

When we received our client’s call, our team went to check the place and informed her that she needs to encapsulate her crawl space because moisture is bad and will eventually affect the entire house!

So we started by insulating the walls and installing our SilverGlo insulation panels, that reflects heat and decrease the thermal conductivity of the material, thus keeping the walls and floor on the upper floor warmer.

And then we installed our CleanSpace drainage matting which is a dimpled drainage matting system that's designed to collect water from the crawl space floor.

Finally our CleanSpace was installed on the floors, “this Plastic membrane blocks the growth of mold and will protect the area from water vapor coming from the ground”

You can see now how clean and beautiful this crawl space has become!

Bad smells and contaminated air in a basement in Montreal-Ouest, Qc

Not only does a wet basement feel and smell horrible, it also create a great risk to your home’s value. Basement moisture can ruin floors and walls, encourage mold, even damage roofing.

So when Mr. Philipe from Montreal-Ouest started having problems with water infiltration in his basement, he contacted us immediately, to take the opinion of one of our specialists in waterproofing.

We sent our specialist Jorge a few days later, and he recommended the installation of a complete waterproofing system to keep his basement dry and healthy no matter what.

As a result, we solved the problem by installing a complete waterproofing system that includes the WaterGuard interior drain which is designed to capture water seepage through walls and leaks along the wall/floor joint,a SuperSump sump pump system for a great pumping performance, a IceGuard  accessory to prevent freezing of pipes, and a LawnScape discharge line accessory.

We are always proud to solve problems of infiltration of water in an efficient way!
