Our customer had big plans to add a second floor on top of their cottage in Gravenhurst, Ontario. Unfortunately, their dreams were put on hold when they found out the current foundation of their cottage would not support the extra weight.

Luckily, Foundation Support Works of Ontario provided a permanent stabilizing solution! 22 Push Piers were installed beneath the home to strengthen and support the added weight of their addition.

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Gravenhurst 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 Gravenhurst, ON
Foundation Issues in Gravenhurst, ON

Cottages have a reputation of having foundation issues. Unfortunately for our customer in Gravenhurst, Ontario, their cottage was built on unstable soil surrounding a swamp. They had big plans to add a second floor shortly but needed the foundation stable enough to handle the extra weight.

After examining the foundation System Design Specialist, Robert Langton recommended to our customer that our team must install 22 Push Piers to stabilize the foundation. Push Piers are straight, steel piers that attach to the foundation wall and extend far below the structure and are attached to firm, stable soil or bedrock.

The cottage is now permanently stabilized and prepared for the added weight of the second floor. Our customer is happy and relieved to have the new Push Piers installed.

I just purchased a cottage and have had two instances of water coming into the basement along the North exterior wall. No a significant amount, but enough that the carpets are wet and there was some standing water in the utility room. I cannot tell if the water is snow melt, a poor drainage system from my waves or something more concerning. Look forward to hearing back from you.

Lake Muskoka 4 seasons cottage, heated year round, built in the late 1950s. About 1000 square feet. Dirt crawl space about 3 feet high, about 6 feet above lake water level, on sand and clay. In early spring some water will pool in crawl space. Musty (mouldy smell, high humidity even in the winter)

House is very old. (+100 years) 2-3/4 storey Victorian. Stone foundation appears to be caving on one corner. Concrete parging is buckled and dirt is sifting in. Previous owners decades ago cut supporting floor joists (I think) to make a stair access to the basement and compromised the support. I would like to know if the steel support beams would rectify the situation. Would like to arrange an inspection and a quote. I have owned the property for about 15 years. Look forward to your reply.

We recently found that our weeper is crushed about 6" into the sump pit. As we noticed our pump hasn't been going off as often as it probably should. We also have a lot of seepage coming up through the cracks in our floor. Our house is only 3 years old and we are located on a very high water table. What would be an approximate cost/quote to fix this issue?
Project Location: Gravenhurst, ON
The back of my cottage is rotting because the joists sit on the granite. My floor is no longer level. I also have a mold issue which will repair itself once the foundation is off the ground. Please contact me. at your earliest convenience. Thanks.

We have a wet unfinished basement - we are looking to get a quote on an internal weeping system and additional sump pump hole created. Would you be available to come by one weekend and take a look at it?
