Crack in Foundation Wall Caused a Flooded Basement in Pickering ON

Crack in Foundation Wall Caused a Flooded Basement in Pickering ON Crack in Foundation Wall Caused a Flooded Basement in Pickering ON

A home in Pickering, ON had basement flooding issues. The problem was located in the side of the foundation of the basement wall. The whole wall had cracked open, and water was draining into the customer's basement. The customer's belongings got damaged over time because of the consistent flow of water in the basement. Not only did the customer have personal property loss, but mould was starting to penetrate the basement as it was always consistently wet. 

The customer called Clarke Basement systems and had our System Design Specialist, Steve Matthews, come out to assess the situation. The customer chose Clarke Basement Systems to fix the issue and had Mark Dougherty come out to install our patented Flexispan® Crack Repair product. Mark used the FlexiSpan® to seal the crack, thus preventing any future water from draining into the customer's basement. 

The customer was ecstatic to hear that Clarke Basement Systems provided a full warrantied solution that the crack would never leak again in the future.

A home in Pickering, Ontario, had some water seepage in their basement that appeared to be coming from the ground level at the wall joint. They called CBS as a trusted friend and referred us to her. She called and explained her concerns, so we sent a trusted inspector to check it out and gave her a free quote.


The solution was to implement a new drainage system and new window wells at the back of her home to ensure water was no longer pooling at the side of her home. This was a preventative investment that this customer made, and she was relieved she acted on it before it damaged her foundation or flooded her basement.

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Pickering 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. We also offer professional installation of LintelLift to repair and support sagging, cracked garage lintels.

Janice from Pickering gave Clarke Basement Systems a call when she discovered some water leaking along the walls of her unfinished basement. We sent an inspector to assess the situation, and he gave her a free quote on the solution he designed for her with his expertise.


She decided to move forward with the solution provided and was very glad she did. We educated her on the detrimental damage water seepage can cause to your home if left for too long. We installed a drainage system in the back to keep water from pooling against her home and damaging her foundation walls.

My house was built in 1984. I just moved in during the winter. I am noticing that after any rain the water pools outside of the house at the one back corner, and inside the house the concrete floor in the same area is wet. Today is the worst I've ever seen it the water has actually pulled away from the corner and along the back wall inside the house and then there is a huge wet spot just in the middle of the room.

I own a semidetached house in Pickering. The crawlspace is damp and mold develops there which I get rid of using chlorine bleach. There are 2 exterior east side wall cracks that I have observed. There is water accumulation at the exterior east perimeter of the home during winter months especially, and very rainy days. I need a dry crawlspace and a way to get rid of the accumulation of water outside the home.
