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.

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.

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.
