Full Basement Waterproofing, Oshawa, ON

Full Basement Waterproofing, Oshawa, ON Full Basement Waterproofing, Oshawa, ON

A home in Oshawa, Ontario had water leaking into the basement. There was water at floor wall joint as well as cracks on the foundation wall that had attempted to be fixed. The homeowners couldn't use their basement anymore due to mold and constant water making the area unhealthy. 

The customer called Clarke Basement Systems to fix their basement problems and make use of the space again. Steve Matthews, the inspector,  explained what we would be doing to fix these water issues. Lucio Flores and the team came in and installed a Watergaurd, CleanspaceTripleSafe Sump pump and an Icegaurd. The Cleanspace was installed on all the walls keeping the moisture and water away from the basement, dropping it all into the installed Watergaurd. The Watergaurd pushes all the water into the TripleSafe Sump pump. The sump pump pushes the water out through the Icegaurd away from the home. This leaves the customers confident in renovating their basement again and no worrying about water damage in the future.

A Church With Basement Flooding in Cobourg, ON A Church With Basement Flooding in Cobourg, ON

A church in Cobourg, Ontario, had a basement that water was found puddling in, in the low areas of the floor. This was happening because of hydrostatic pressure pushing water up through the floor. With constant puddles, comes water damage and odours that no customer wants.

The customer called Clarke Basement Systems and we came up with a solution that fit their needs and budget. Our TripleSafe sump system was installed to rid the area of the pressure and stop any future flooding. Two IceGuards were also installed on the discharge line to prevent the possibility of future freezing of the lines. The church is now waterproofed so that the customer does not have to worry about flooding or water damage in the future.

Concrete repair experts

The sunken and cracked concrete around your Cobourg 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.

Job Stories From Cobourg, ON
Crack in Foundation in Cobourg, ON

Our customer living in Cobourg, Ontario, contacted our company regarding a crack in their basement foundation. They wanted to finish their basement, but the issue needed to be fixed first. They needed a quick and budget-friendly solution.

Steve Matthews, System Design Specialist, assessed the crack and provided a permeant solution. Mark Dougherty, a Foreman, installed:

  • a FlexiSpan® Foundation Crack Repair System

The FlexiSpan® System is a polyurethane polymer that will never dry out or crack. This system is perfect because it bends with the natural movement of the foundation.

Our customer was thrilled to have a permeant solution for their cracked foundation. They are now able to finish their basement with no worry of future water damage.
