The problem: This Pierrefonds client had a crack in his foundation wall. As we can see in the photo, it was still quite important.


The solution: We injected the crack with a polyurethane and then we covered it with our product called Flexispan. At the crack, we dug a small hole to put a drainage membrane to redirect the water.

We repaired the basement slab that was sagging at this house in Pierrefonds. Symptoms can be clearly seen in the cracks separating between the top of the interior walls of the basement and floor upstairs. By installing our slab piers, we did not just stabilize the slab, but also we were able to close the existing cracks as you see in these 2 pictures.

In Pierrefonds, this homeowner faced a common yet troublesome issue - a damp crawlspace, which can be seen in the before photo displaying signs of moisture and possible damage risks. Fortunately, our team stepped in with a seamless solution. On the floor we installed CleanSpace drainage matting and TerraBlock since the temperature fluctuation was significant. And on the walls we installed SilverGlo thermal insulation. As noticed in the after photo, we transformed the previously damp and neglected crawlspace into a dry, energy-efficient, and healthy area under the home. This upgrade not only solved the current moisture problem but also provided a durable solution that supports a healthier living environment above.

Our Basement Waterproofing Solutions in Pierrefonds

Basements are a common spot for water intrusion in homes due to the soil around them. When soil gets wet, dries out, or is displaced, it can cause shifting around the basement and lead to cracks or other vulnerabilities in the exterior wall. Though this is a common problem, the right solution for your home can be a unique combination of techniques and products. Thankfully we carry all of the most up-to-date basement waterproofing products available, including sump pumps, perimeter drains, wall repair products, and more.

Don't let water intrusion stop you from using your basement the way you want to. Whether it's a simple storage area or you're looking to finish the space, keeping it dry will do wonders for the long-term health of your home.

Professional Basement Finishing & Remodeling Services

If you see your unfinished basement as an opportunity for expansion rather than just another dingy, dark room for storage, then you've come to the right place. We can improve and transform all aspects of your basement, including the walls, floors, ceiling, insulation measures, and finishing touches to give it your special flare. The benefits of basement finishing are endless and can create a totally new, usable space in your home. Some design ideas we can help you explore include:

  • Additional living space
  • In-law apartment

Foundation Repair & Structural Improvements by Systèmes Sous-sol Québec

Foundation problems can affect your entire home in significant ways. If the foundation shifts out of place, it can no longer properly support your home and may result in slanted floors, cracked walls, cracked ceilings, windows and doors sticking in place, and more. Similarly, when your foundation is cracked it can allow for serious water intrusion or pest infestations. Both pests and water use foundation cracks as their way into your home where they wreak havoc, especially when mold begins to grow. What starts as mold or mildew around the foundation can negatively affect whole-home air quality from top to bottom and result in wood-rot, compromising the structural integrity of your home.

Foundation products & services we offer:

  • Push pier systems
  • Helical foundation piers
  • Crawl space supports
  • Basement wall anchors

With our full suite of foundation repair products, we can address almost any foundation problem you may be having. Unsure about the health of your home's foundation? Start with a free inspection and cost estimate from us.

Crawl Space Encapsulation, Sealing, & Other Repair Services

Systèmes Sous-sol Québec installs the unbeatable CleanSpace® crawl space encapsulation system that will take your crawl space from dirty and useless to clean and usable storage space. In addition to sealing off your crawl space and making it waterproof, we also offer crawl space jacks for structural support and prevention of sagging crawl space ceilings— this will also help prevent sagging of floors above the crawl space. To finish off your new crawl space, we also install access wells and thermal insulation to protect your property.

The CleanSpace® system completely transforms your dirt floor crawl space into a sealed environment, dramatically reducing the humidity levels. Lower humidity levels can reduce or eliminate mold growth, rot, and pests from your crawl space. This ensures long-term home health and air quality, starting with your crawl space. We offer free estimates on any of our crawl space encapsulation and repair services in Pierrefonds.

Job Stories From Pierrefonds, QC
Repairing a crack in a foundation with Flexispan in Pierrefonds, Qc

This crack repair project was done in Pierrefonds. The client found that his basement had abnormal humidity and when he opened the wall he found that there was a fairly large crack in his foundation. He called in an inspector to have his expertise on what to do with this crack and the inspector told him to bring in experts to fix it and by doing a quick little search on the internet this client came across our page and he filled out a free quote request.


When our representative came to the customer and noticed the condition of the crack, he suggested to repair the interior by injecting a polyurethane and then cover the crack with our product called the Flexispan. This product is a flexible polyurethane that is spread over the crack to seal it completely. In addition, a cavity is dug in the ground to insert a drainage membrane in the event that water flows behind the Flexispan.


Following our intervention, this Pierrefonds client can have peace of mind and no longer have to worry about this crack, because it is now very well sealed.

I'm thinking a sump pump might be what I need. With all the rain we've been having I noticed that there was an accumulation of water near the pipe in my crawlspace that leads to the city pipes outside (if I'm explaining myself properly). There is a bad odour coming from it. My house is built on higher ground and since I have bought my house (13 years ago), I have not had any issues until now. I do not have a French drain. Would I be able to get an evaluation?
