Solution to Ground Water Seepage, Toronto, ON

Before After
Solution to Ground Water Seepage, Toronto, ON Solution to Ground Water Seepage, Toronto, ON

A home in Toronto, Ontario, had a problem in the basement. Over the years there was ground water leaking into the space. It was damaging the finished walls, floor, personal items. It was also causing odours and the homeowner did not want it to effect the rest of the home. They were also unable to use the basement space.

The customer called Clarke Basement systems and spoke to Claude Mathieus, who explained the process that would be done to the basement. Lucio and the team came in and installed WaterGuard, Flangless WaterdGuard, ThermalDry Wall and SuperSump. This system ensures that any ground water penetrating through the basement foundation walls or building up below the basement floor is captured and pump away from foundation. These products were used around the full perimeter of the basement and across the middle, below the concrete floor, to ensure no more basement leaks.

The home owner can now refinish basement and use the space with no concerns of ground water leaking in.

Concrete repair experts

The sunken and cracked concrete around your York home is both an eyesore and a safety hazard. It is also likely to get worse with time, but we can fix it for you!

Our experts use PolyLevel, a superior polyurethane foam to provide reliable concrete lifting & leveling solutions. Small holes are drilled in the concrete and the expansion of the foam lifts & levels the concrete. The majority of contractors you will call use mudjacking instead of foam. Mudjacking is heavier, requires larger holes in the concrete and does not last as long as PolyLevel.

If your home has cracked concrete steps, pool decks, patios, or other slabs, then NexusPro is the right solution. NexusPro repairs concrete cracks and joints and is ultra-durable, so it will withstand UV rays, extreme weather, and more.

After utilizing our expert concrete repair solutions, consider the powerful concrete sealant, SealantPro. SealantPro further protects your concrete by bonding with it to guard against oil, gasoline, liquids, and other debris. In just one coat, SealantPro extends the life of your concrete by 3 to 5 times overall. 

Call us today to learn more about our proven concrete leveling, cracked concrete repair, and concrete sealing techniques.
