Our kitchen is the heart of the home, but what is the crawl space? The backbone of your home. An often forgotten but essential place of your home's overall functionality. For this house in Innisfil, Ontario, the customers called us as they were concerned with the pungent odour coming from the crawl space and making its way to their main floor. System Design Specialist Dean Merendino created a well-suited, long-lasting solution for the crawl space. An organized installation team installed our SmartPipe® drainage system and a SmartSump®. For insulation and preserving energy, we set up our ThermalDry® wall system. To encapsulate the area, our CleanSpace® vapour barrier was installed to keep the site clean and dry. Lastly, we installed our IceGuard® discharge line protection system.


The customers were so pleased with the turnout of the crawl space and couldn't believe it was the same one they were having problems with. They immediately noticed a difference in the air quality as there was no longer a nasty odour bothering them.

In the midst of a basement renovation, a family in Innisfil, Ontario discovered water seeping into their basement during heavy rain and thaw season. Frustrated and looking forward to finishing their reno, the customer turned to Clarke Basement Systems to find a solution to their wet basement woes.

Sales Rep Alex Barnik reviewed the situation and decided upon a complete basement waterproofing system to fix the problem. Our team used CleanSpace® Vapor Barrier to seal the walls from moisture. Next we installed a WaterGuard® Drainage System to feed water to the sump pump, and a SuperSump® system to ensure the basement stays dry. The family was extremely satisfied with the final product and their basement is now a safe and dry area to complete their renovation.

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Innisfil 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.

Job Stories From Innisfil, ON
Encapsulation and Waterproofing in Innisfil, Ontario

No one wants to discover a wet basement during a renovation, or at all for that matter. But for an Innisfil, Ontario family this was the unfortunate card they were dealt. They wanted to turn their basement into a play area and laundry room, but a wet basement was holding them back. They had recently purchased the 43-year-old home, but they think the problem had been going on for some time.

They reached out to Clarke Basement Systems looking for a solution. System Design Specialist Alex Barnik met with the customer and helped them decide on a plan to waterproof the basement, and at the same time relieve their frustrations. We installed CleanSpace® Vapour Barrier, a WaterGuard® Drainage System, and SuperSump® system. Collectively these products work together to prevent and expel any water in the basement and keep the basement dry year-round. The family was thrilled with the work and loved the look of how bright the space became. They were able to continue their renovation, creating a useable space in the house and freeing up some desperately needed space.

Water seeping under the wall into crawl space. Not much. Got sub pumps. Just want to see if we can stop it. Never had an issue before. But with all the rain this spring the water levels are high. Please contact me. Thank you

Bought an old cottage and want to have the crawl space made pest proof and to make sure proper venting.
Project Location: Innisfil, ON
We live in a 1967 built cottage that has been renovated, with the exception of the crawl space. We are dealing with moister issues in our main living areas. I suspect our crawl space condition has much to do for this. The previous vapour barrier has all but disintegrated on the dirt floor of the crawl space. Insulation wrapping the duct work has also disintegrated and fallen off. I'm looking for a quote on potential full encapsulation/new vapour barrier laid out on the dirt floor. The crawl space has very tight clearance, and is approximately 1100 square feet. Thanks, Mike

I have a periodic water seepage near a corner of my basement. There is a plywood covering the wall, in the utility room. I have cut the wood back, near where I think that the problem may be. As well, I would like to speak to someone, regarding the installation of a back up sump pump. As well, my basement is not finished, and this might be a consideration. The house is approximately 7 years old. (poured foundation)

I live in a roughly 1000 square foot home with a crawlspace. The only things in the crawlspace are furnace pipes and a water meter. It's damp in the crawlspace and my water meter guy refused to go down there because of a bit of water on the floor in 2018. I have a mandatory appointment for July 18th for someone to inspect the water meter and possibly replace it. I'm hoping to encapsulate the crawlspace (with sump pump?) before the service guy comes. In 2019 I sealed the only indoor hatch to the crawlspace when I replaced my laundry room floor (the water heater had leaked and rotted out the floor and joists). Before having the crawlspace encapsulated, I'll have to have my handyman come and create a new indoor hatch to the space. Just wondering how busy you are and if you could give me a ballpark estimate. I'm hoping to fix the moldy smell and also to alleviate my icy cold winter floors. I'd also like to be able to use the crawlspace for storage. Thanks! (I own the house.)
