A home in Toronto, Ontario was experiencing basement flooding due to a window that was located close to a down spout. It was not draining away the water fast enough and when it rained the homeowners spent a lot of time mopping up the water to prevent damage from the flooding.  

The customer called Clarke Basement Systems and Claude Mathieu explained the solution we came up with to rid them of their problem. Don Clarke and the team came in and excavated to create new positive drainage.  They installed the new Sun House Window Well enclosure allowing  more sunlight in and none of the leaves and debris backing up the drain would cause the basement to flood again.  

The homeowner was extremely happy knowing they wouldn't have to waste any time cleaning up water that leaked into the basement. They wouldnt need to pay for damaged floors and the window brought in more light.

A home in Toronto, Ontario had a basement that was very damp and leaked in several locations when it rained. The basement is large and they would see water coming up through the ceramic tile joints.  The issue was hydrostatic water pressure from below the house, as well as moisture penetration through the foundation walls. This was happening due to the failure of a proper external waterproofing system when the home was built. The basement was finished and they wanted to have a space with no water leaking in causing mold and damage.

The customer no longer wanted to deal with a smelly basement and damaged items so they called Clarke Basement SystemsJose Martinez and the team installed a WaterGuard around the perimeter of the basement to capture ground water.  A ThermalDry Wall membrane was used to direct moisture from foundation walls and direct it to the WaterGuard.  A SuperSump sump pump with UltraSump Battery Back-up in case of power failure was installed to collect water and discharge it outside through our IceGuard. This system ensures that any ground water penetrating the basement is captured and pumped away from foundation. The customer is happy knowing they can finish the basement and use the space with no worry about water damage.

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 home 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.

Concrete repair experts

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.

Job Stories From North York, ON
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.

Sonnet Court in North York
Our house is a 1962 North York semi with a partially finished basement. We've owned the house for two years; every spring and winter, especially in periods of heavy rain or snow melt, we seem to get some water or dampness coming through the cinder block walls of the unfinished section of the basement. We had some cracks around our foundation & driveay which were repaired in the summer, which we thought was the source of the problem. However, with the recent snow melt, we are still getting water seepage in all the same places. I'm afraid either our weeping tiles are overflowing, or the moisture is coming in through the ground. Each of the three instances of water seepage is coming through the cinderblock walls, about 6 inches off the floor, and it is worst in the cantina from the adjoining wall with our neighbours. We would love it if you could provide some options/solutions. We would like to finish the basement and put in a bathroom, but don't want to do so until we find and fix the source of these water issues. Thank you!!
