Full Basement Waterproofing in Oshawa, ON

Before After
Full Basement Waterproofing in Oshawa, ON Full Basement Waterproofing in 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 fix. The homeowners couldn't use their basement anymore due to mould 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 correct these water issues. Lucio Flores and the team came in and installed a WaterGuard® Below-Floor Drain, CleanSpace® Vapour Barrier, TripleSafe™ Complete Sump pump and an IceGuard® Discharge Line System. The CleanSpace® was installed on all the walls keeping the moisture and water away from the basement, dropping it all into the installed WaterGuard®. The WaterGuard® pushes all the water into the TripleSafe™. The sump pump pushes the water out through the IceGuard® away from the home. This leaves the customers confident in renovating their basement again and no worrying about water damage in the future.

A Flooding Basement Church in Cobourg, ON A Flooding Basement Church 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™ Complete Sump Pump System was installed to rid the area of the pressure and stop any future flooding. Two IceGuard® Discharge Line Systems 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.

Fast & Affordable Concrete Repair

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
Basement Waterproofing and Mould Removal in Cobourg, Ontario

Every homeowner is afraid of mould. It’s unsightly, smells, and can have terrible health effects. In many cases it can simply be scrubbed away, and the issue is gone, but sometimes mould can take over and cause damage to your beloved space. Caused by moisture, when you find mould in your home, you’re usually dealing with not only a mould problem, but a water seepage problem too. 

Katy, a homeowner in Cobourg, Ontario, owns a gorgeous bungalow with a finished basement. She discovered that water was entering the front wall of her home in three different spots, causing mould to grow and build up. She was concerned about potential health issues caused by the mould and it was difficult to use the space. With a bungalow only consisting of two floors, she was unable to use almost half of the space in her home, causing frustration and cramping on the main level. A fun space to entertain and shoot some pool was inaccessible and the problem was only getting worse. 

Katy reached out to Clarke Basement Systems for a permanent solution for her mould madness.  A team was sent out to remove the mould, along with 83 feet of drywall and insulation. System Design Specialist Ryan Hanlon designed a waterproofing system and Foreman David Jackson got busy installing it. The system consisted of CleanSpace® Vapor Barrier, WaterGuard® and a TripleSafe™ Sump Pump. Together these products prevent moisture from entering the space and send any water that does enter into a drain where it is pumped out. Since most Ontario basements deal with high humidity on a regular basis, we also installed an Aprilaire De-Humidifier to ensure the basement stays dry and safe. 

Since the repairs have been done Katy has been ecstatic that she can finally use her basement again. She was very pleased with how the work turned out and has played many games of pool since its completion! She has since refinished her basement too and can finally entertain guests in a dry and safe area.

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.

The east side basement wall (which is concrete block foundation) has always leaked a bit. I think a lot of the house may have been water proofed etc at some point... not exactly sure... but I'd like a free quote on possibly fixing the leaking on the back wall in a few different spots and possibly a sump pump installation.
