A home in Toronto, Ontario had a problem located at the side of the home along the concrete walkway. The concrete walkway was sinking in various places along the house with the vast majority of the slabs sinking towards the foundation. The sinking concrete was causing trip hazards, and water was flowing towards the foundation. If it continued, it could lead to future basement and foundation problems. 

The customer called Canadian Concrete Leveleing, and John DiNicolantonio explained what would be done to help fix the problem. Kyle McKeown and the team came in and used the PolyLevel® Foam and NexusPro® Joint Sealant. The foam followed the path of least resistance beneath the slabs to fill all of the voids and lift the concrete. The NexusPro® Joint Sealant is then used to seal the gaps to prevent water from damaging the foundation. The customer was happy we could eliminate the risk of future foundation damage and rid them of all trip hazards.

A homeowner in Toronto, ON had too much water flooding their lawn and walkway from the sump pump discharge and downspouts. This area was so saturated that the homeowner and his family could not use this part of the yard. It was a frustrating situation. The family loved to spend time in this area in the summer.

 Claude Mathieu, Senior System Design Specialist, visited the homeowner and discussed ways to solve this problem. To get the water under control, Don Clarke, Project Foreman, and production crew installed a TripleSafe™ Sump System, buried discharge line, Heat-Line and Drywell. The system works together to send water below grade to the Drywell. It helps eliminate surface flooding. The TripleSafe sump system maintains pumping capacity when needed.

 Now on bright, sunny days, there’s nothing better for the family than enjoying their well-drained yard in the summertime or any time during the year.

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your North 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. We also offer professional installation of LintelLift to repair and support sagging, cracked garage lintels.

Job Stories From North York, ON
Storefront in Toronto Needs Waterproofing

Store owners of a brokerage firm in Toronto, ON, had a bit of a water seepage issue that was ongoing for some time. After realizing it was getting progressively worse, they decided to call Clarke Basement Systems for a solution that would keep them safe from mould growth. First, we placed our patented WaterGuard® as a drainage system. Then they closed off the area with our CleanSpace® water vapour barrier. This will protect the place from water seepage and guide it to the drainage system, later discharging it outside the store.

Wet Toronto, ON Basement Fixed With WaterGuard and TripleSafe

The City of Toronto, ON was having issues with one of their water waste plants, which was suffering from water intrusion into the basement after heavy rainfall. The building was 50 years old and was in need of repair, so they reached out to Clarke Basement Systems to remediate their problem.


Claude Mathieu went to the water waste plant to assess the situation, and found that they were in need of effective drainage. He suggested the DryTrak interior waterproofing system, combined with the Flangeless WaterGuard perimeter drainage system. He also advocated the use of the TripleSafe Sump Pump for added protection against future flooding. Primary Foreman Rob Trevisan brought a team of specialists to perform installation, and they have saved the water waste plant from future water issues.
