Wall Crack Leads to Sleepless Nights in Courtice, Ontario Wall Crack Leads to Sleepless Nights in Courtice, Ontario

Trying to fix a repair repeatedly is frustrating. It leaves you wondering if the issue will ever be resolved and can keep you awake at night.

In Courtice, Ontario, a customer was tired of dealing with a pesky water leak in his basement. The problem had persisted for years, and he had tried many different store-bought solutions with no success.

Clarke Basement Systems came in and finally changed his basement for the better. System Design Specialist Ryan Hanlon met with the customer and inspected the basement before recommending our FlexiSpan® Crack Repair.

Foreman Ali Fereidouni started by injecting the polyurethane sealant within the crack before caulking the exterior. FlexiSpan® stays durable but can still shift without losing its seal, keeping seeping water at bay. Lastly, a drain is placed over the entire crack in case of any future gaps that occur.

The customer doesn’t have to worry about his basement anymore and can use the space for storage again. No more headaches and sleepless nights!

Our customers were in the middle of finishing their basement to sell their home when the contractor spotted a leak in the foundation. Our customer wanted the crack sealed immediately to stay on schedule with the renovations and retail listing.

Our team installed a FlexiSpan® Foundation Crack Repair System that never dries out or breaks since it adapts with the foundation.

The customers were thrilled to have a dry, protected basement. They were able to finish renovating the basement and finally put the house up for sale.

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Courtice 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 have a slow leak on the basement wall, this became noticeable some weeks back when we had heavy rainfall. I pulled away the drywall and found two locations where water beads were rolling down the wall after another heavy rainfall. We are looking to arrange a visit from your team to assess the cracks on the wall and to provide a quote to address the issue. Thank you, Graham

We have a crack in our foundation that is leaking. It is in the unfinished section of our basement right behind our washer & dryer. Vapour barrier goes about halfway down the wall and now I can see water behind the barrier. The crack comes down below the vapour barrier and in the past (usually in the spring when snow is melting, we would occasionally see a bit of water. Today I was doing something behind the dryer and saw some water on the floor.
