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

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.

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

There is water leakage in the crawl space in a couple of areas and I would like someone to take a look at it and give me an estimate on repair. Thanks very much

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.
