Basement Waterproofing Contractor in Montreal, Quebec City, Laval

Sump pump and SaniDry™ dehumidifier

Since Basement Systems, Inc. was started in 1987, we've been upgrading and perfecting our product line to always be the best available.

The issue of water in basements has been an ongoing problem since the first basement was built. Sub-floor structures like basements and crawl spaces are not perfect by design and are built on soil that constantly shifts and moves. Water collects around and under basements and can leak in through walls, floor slabs and in between the walls and floors.

There are contractors out there that have similar products and solutions to basement water problems. The line of Basement Systems products have been developed, produced, and updated for over 25 years in basements. We know basements!

Let our waterproofing professionals give your home a free basement assessment and fix your water problems once and for all. Being in the business as long as we have, there is not a problem we haven't seen and fixed. We serve residents in Quebec City, Montreal, Laval and nearby.

    Insulation of crawl space discovered in Godmanchester, Qc

    PROBLEM

    Mr. Bruno's crawl space was uncovered and created humidity in the rest of the house. The client did not want this to affect his family's health in the long term.

     

     SOLUTION

     Systèmes Sous-sol Québec’s team suggested a solution that guaranteed a dry space all year round. A solution including 3 products; TerraBlock insulation, SmartDrain and CleanSpace encapsulation product.

    Our TerraBlock insulation provides a puncture-resistant vapor barrier on all surfaces it covers - one that will not be damaged by water or support the growth of mold, rot, and mildew.

    As for the SmartDrain, it is a floor drain installed at the lowest point of the crawl space to intercept water infiltration caused by plumbing leaks.

    And finally the CleanSpace will prevent the growth of mold. In addition it is odorless and very safe to use.

    Waterproofing a wet basement in South Lancaster, QC

    Here is another wet basement that has been waterproofed in South Lancaster.

    When our client Joy found our website, she knew that we can fix her basement problems, without taking too much time.

    So we installed a complete waterproofing system including 25 feet of WaterGuard interior drain to intercept water coming in, a TripleSafe sump pump system with three pump system for more protection, and finally our SaniDry Sedona dehumidification system which is the best in the market.

    Waterproofed basement in Gatineau, QC

    Our clients in Gatineau were suffering from water infiltration problems in their home's basement which caused humidity in the area and has also lead to severe coldness in the basement that has reached the whole house as well.

    As you can see in the first picture, the water has penetrated the floors and structural paint damages have occurred on the walls.

    Furthermore, our professionals have installed a WaterGuard system, our SuperSump sump pump, as well as our SaniDry and IceGuard systems and finished it with the EverLast wall restoration systems.

    Our clients are now very happy since they did not face any humidity problems again and can enjoy their new warm, dry and beautiful basement.

WaterGuard® drainage system

How Our Waterproofing Solutions Work

WaterGuard® is a waterproofing drainage system that rests under the floor slab. It keeps your basement dry while being clog-free from existing soil and dirt.

The openings and the extending flange collect water and carry it away from the foundation walls.

By adding a TripleSafe Sump Pump System you can ensure a permanently dry basement.

DryTrak® system DryTrak® basement water control system

Some basement floors and footings are one solid piece of concrete. These "monolithic" floors cannot be jackhammered to install some systems. For these instances we offer the DryTrak® system that sits on top of the floor and works as a basement drain.

    Customer Testimonial

              Yes, we were very impressed with Systèmes Sous Sol’ professionalism, the letter beforehand outlining our responsibilities, precautions to be taken, etc. The book you sent ahead of time to help us know the company, possible solutions to the issues homeowners face was very well done. As a former graphics designer, I was impressed. It’s pretty scary when as a homeowner you experience leaks in your home (small or large) and companies you call for quotes don’t respond, yet you can’t move forward as was our case. The laundry room and adjoining bathroom are in their original state (53 yrs.old) needing to be renovated but having to deal with water infiltration every few years. Hi again, I forgot to mention the prompt service we received from Sam. When I had questions, he responded very quickly. He phoned us the night before and that morning too because he was going to be a bit late. He did a great job! Now we can move forward knowing that the problem was resolved thanks to your company.

    Customer Testimonial

              I contacted Systemes Sous-sol in April/2021 via the internet and quickly received a reply from their office in Laval through which I booked a free inspection and estimate with Jerry Evangelatos, System Design Specialist for April 5th, 2021. Mr. Evangelatos drove to Wakefield, Quebec and sat down with me to fully explain the "Dry basement solution". His presentation was clear and precise and provided full details of the systems, the cost, the time for the work. the lifetime guarantee and the preparations required. I had read the complete booklet sent to me earlier but Jerry showed me an additional video of the work to be done and with all of this information. I was able to make a decision immediately after I fully understood this system. He was able to give me the date of April 29 for the installation. Later, I received a call from Valerie, who was pleasant, professional and enthusiastic and who offered me an earlier date. After confirmation with my plumber, I was able to accept this new appointment. On Tuesday, April 19th, two company employees arrived, having called me to inform me when they could get here. I was very impressed with the friendliness and professional manner of Felix, who was obviously perfect bilingual, very competent and very comfortable with people. When he and his fellow Worker, Quan, arrived, they spent some time with me in the basement going over the work that would be done, the estimated time it would take and offered to respond to any questions. Felix reviewed the contract I had signed with Jerry and then set about their work. I have never seen two men so motivated, so knowledgeable and so willing to do this job as efficiently and carefully as possible. They were both respectful of me and my home and did their work with as little disruption as possible. They worked as a team and obviously knew what needed to be done and how the best to do it. Felix kept me informed with regard to their progress and always asked whenever he needed to use an indoor plug or whatever. I have already spoken to friends and neighbors about the quality of the workmanship and the integrity that both Felix and Quan demonstrated throughout the 3 days here in my home. They worked together tirelessly and rarely if ever stopped for breaks. Felix was extremely professional and knowledgeable and though, obviously in charge, treated his coworker with respect at all times. Quan worked comfortably alongside Felix, and both of them worked with amazing strength and speed and wasted no time in bringing the job to completion in a timely manner. I have never been so impressed by two young men who are obviously both loyal employees, promote their products with confidence and respect and are wonderful ambassadors for your company and worthy of my respect and admiration. I compliment the entire company on its successful completion of this contract. Sincerely,
    Sally S.
