An ounce of prevention is worth a pound of cure, and for a Toronto, Ontario, customer the saying couldn’t be more accurate.

A retaining wall separated his driveway from his front lawn, but over the years, the retaining wall had tipped. If the wall collapsed, it would cause damage to his front yard, possibly the vehicles in the driveway, and the repair cost would be into the thousands. Not to mention the stress of redoing his yard and driveway.

The customer contacted Clarke Basement Systems hoping for a solution that would protect his property and save him money. System Design Specialist Ron Monk met with the customer at his home and after inspecting the situation, developed a plan using our GeoLock™ Wall Anchor System to straighten and stabilize the retaining wall.

GeoLock™ wall anchors go deep into the ground and connect to a wall using a series of rods and plates. Foreman Don Clarke started by excavating the area surrounding the wall before installing the system. Anchor rods and earth anchors were installed next before wall plates were placed overtop of them. Once installed, the plates were tightened accordingly, to straighten and stabilize the wall. Finally, the area was backfilled, and our 25-year warranty ensures the wall will stay stable for many years to come.

Thanks to our system, the customer’s wall is stable, and his investments are protected. He was ecstatic that he didn’t need to replace the whole wall, or complete even more repairs if the wall had collapsed. A happy customer and a job well done by the Clarke Basement Systems team!

Solution to Ground Water Seepage in Toronto, ON

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

The customer called Clarke Basement systems and spoke to Claude Mathieu, who explained the process. Lucio and the team came in and installed WaterGuard® Below-Floor Drain, Flangless WaterGuard®, ThermalDry® Wall Insulation and SuperSump® Premier Sump Pump System. This system ensures that any groundwater penetrating through the basement foundation walls or building up below the basement floor is captured and pump away from the 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 homeowner can now refinish basement and use the space with no concerns of groundwater leaking in.

Fast & Affordable Concrete Repair

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.

  • Uneven Patios

Noticing crack in the interior and exterior of my house. I believe that this maybe as a result of my house requiring waterproofing and pressure being put on the exterior.
