Basement Waterproofing Systems in Greater Toronto

The TripleSafe® Sump Pump, combined with a SaniDry® dehumidifier, is the ultimate in basement waterproofing and humidity control.

At Clarke Basement Systems, we understand that a large part of your living space is the basement. If you live in a one-story home, your basement could be half your square footage! That is why it is important to be vigilant against basement flooding, a common occurrence in homes new and old and rarely a one-time event.

Luckily, our crew can install a quality basement waterproofing system in as little as one to two days. We use patented Basement Systems® products, including weeping tile and interior drainage systems, sump pumps, and dehumidifiers. All of which have a nationwide track record of keeping basements dry for more than 20 years.

Understanding basement flooding & how to fix it

Two factors contribute to basement leaking — the clay bowl effect and hydrostatic pressure:

  • The "clay bowl effect" & your foundation

    When building a home, contractors begin digging a hole in the ground a little larger thhnan the space your basement and foundation will need. Then they build the foundation inside this space and pour the concrete floor. Once they finish the foundation, they use some of the excavated soil to fill in the gap around the outer edge of your foundation. This "backfill" soil will be loose and fluffed from the excavation. Meanwhile, the untouched "virgin soil" may have been settling for hundreds, even thousands of years.

    What does this mean for you? The backfilled soil surrounding your foundation will always be looser and more absorbent of water than the dense, hard-packed soil around it. This forms a sort of "clay bowl" around your house, one that creates an artificial water table around your home. Water collects the most right around your foundation, exactly where you don't want it to be.

  • Hydrostatic pressure & wet soils

    Water is heavy! As the soil around your home becomes soaked with moisture, the soil will expand, and the weight of the water will press on your foundation, known as hydrostatic pressure. As hydrostatic pressure builds against your foundation, water enters through any way possible, including concrete cracks in the walls or floors, openings around pipes, basement windows, or even directly through the porous concrete. If you have block walls, water may pass through the block and begin to fill the open cavities.

    However, the most common way water enters a home is through the foundation wall-floor joint. We find that most flooded basements start with a leak here.

Why invest in basement waterproofing?

Homes with wet basements are incredibly difficult to sell. In fact, reports show that a wet basement is a top "red flag" that deters buyers. Combined with our lifetime written warranty, which is transferable to the next owner, home buyers will be confident that their home is protected, restoring 10% or more of its market value.

Also, after basement waterproofing, many consider basement finishing since it is the most cost-effective way to add living space without the hassle of adding pipes, electrical wires, and utilities needed for an addition.
