 Twenty years ago, the Byam’s built a beautiful log home as their retirement home. Over that time, they began noticing severe cracking in interior and exterior walls as well as windows and doors becoming out of square and difficult to operate. Later determined that one section of the home had been built over poorly compacted fill soils and caused settlement of nearly 5 inches. A permanent solution was required to stop the settling foundation and, if possible, restore the home to its original, level position. 

 After considering several options, Clarke Basement Systems was the contractor of choice due to their high level of professionalism, reputation, and thorough explanation of the solution. Clarke Basement Systems excavated the soil around the foundation walls and installed ten (10) Foundation Supportworks™ Model 288 Push Piers to permanently stabilize the foundation. L-shaped foundation support brackets positioned below and against the footings; steel pier sections were driven approximately 20 feet to competent load-bearing strata. Hydraulic cylinders were then used to lift the foundation nearly 5 inches to a level position, closing cracks throughout the home and bringing the doors and windows back into operation. The homeowners now have peace-of-mind thanks to their permanently stabilized, and they have the added assurance of a 25-year warranty.

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Coboconk 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.

Need an estimate on sealing a basement in coboconk.
Project Location: Coboconk, ON
Purchased a cottage with a crawl space. Space is full of garbage and insultation that I'd like to have removed. Dirt floor which I'd like to have covered so I can use the space.
Project Location: Coboconk, ON
Our crawl space is terrifying! The sump pump is working hard. The spiders are plenty.
Project Location: Coboconk, ON
We have a sump pump in the cellar but no hole and the floor is very thick concrete. We are curious about the cost to have someone come in and put in a hole and update the system. We dont have a lot to spend so we need to know what we are getting into.

Hello, We have a block concrete basement that is leaking water and need to have waterproofed!
Project Location: Coboconk, ON
The property is waterfront with a good slope down to the lake but the basement is damp all summer. I was thinking if the back foundation wall (the one holding back the moisture filled earth) was made waterproof, less moisture would push its way into the basement alleviating much of the dampness in the basement. The cinder block foundation does have a black tar coating around it, and there seems to be sand all around the house. The building is approx. 36 years old. Thank you, Robert Stabile
