Before After
Cold Cellar in Need of Waterproofing, Cheltenham, ON Cold Cellar in Need of Waterproofing, Cheltenham, ON

A home in Cheltenham, Ontario, had a problem located in the cold cellar of the home. Groundwater was seeping in at the floor/wall joint. The homeowner wanted to store items in this room safely without them getting wet and damaged.

The customer called Clarke Basement Systems and spoke to Ben Wallis who explained the solutions to their problem. Luke Havercourt and the team were able to complete the work in one day. They installed WaterGuard sub-floor drainage system and ThermalDry wall membrane. They were installed to prevent groundwater from getting to the floor, by collecting any future water or moisture into the newly installed WaterGuard  around the perimeter.

The customer is satisfied because they will no longer have groundwater on the floor in the cold cellar, and can safely store personal items with peace of mind.

Concrete repair experts

The sunken and cracked concrete around your Cheltenham 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.
