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.

Where do you go when you’re looking for something you haven’t seen in years? Typically, it’s the basement storage room. These rooms are generally unfinished but make a great storage space.

A customer in Pickering, Ontario, noticed water was pooling on the floor of his storage room. His belongings were always getting wet, and he was concerned the leak would grow and create a more severe issue. He decided to deal with the problem sooner rather than later and reached out to Clarke Basement Systems.

System Design Specialist Chris Luke met with the customer and inspected his basement. He found a crack in the poured concrete foundation and showed the customer our FlexiSpan® Repair System. The customer was happy to hear the repair was non-invasive and could be done in a day. 

Foreman Lucio Flores started by digging a small hole in the floor for a dry well. Next, he sealed the crack by injecting it with a urethane-based sealant. A polyurethane foam strip was then applied on the wall over the first seal to complete the repair. If there is the slightest bit of moisture, the foam strip will drain it into the dry well.

 The customer is surprised by how fast the team repaired the foundation crack. He’s very excited about using his completely dry basement and not worrying about unwanted water in his home again.

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.

It appears I have a small crack in my basement foundation within the crawlspace might be a landscaping issue as the water pools on the side of the house and doesn't drain happened last winter when the ground was still frozen and we had a heavy rainfall. So I'm not sure if the crack needs to be repaired/filled or the drainage outside in that area needs to be fixed? I have a small deck and patio stones laid out where the crack appears and there's also a heavy population of trees in close proximity...

Vicinity of Yeremi St in Pickering
I had a leak in my basement in January. It was minor and hasn't recurred but it seemed to have come from a small crack in the concrete foundation. The insurance company is now insisting that I fix something that is not causing an issue. I believe an injection would satisfy them. I need someone to let me know if this can be done, how fast it can be done any what it will cost. It is rented property, I don't actually live there but I can be there on Saturday if someone can come by. The crack is under an enclosed stairwell but I have cut a hole in the drywall for access. I really need someone to see it to determine what to do. Cheers, Lindsay
