Before and After Pictures from Gooderham

A homeowner in Gooderham, Ontario, was complaining of an ongoing damp feeling in their crawl space. The moisture in the crawl space caused mould to form leading to structural damage to the floor joists. The customer was worried about the health and safety of their home.


Our team at Clarke Basement Systems was able to fix the problem with a complete encapsulation. 1.5-inch Styrofoam was sprayed onto the walls and a wall membrane was added installed over the Styrofoam. We also introduced a SmartSump™ Crawl Space Sump System. This sump pump system is specially designed for crawl spaces to protect against flooding or leaking water.


The homeowner was pleased with the finished project. The system will protect this home from future water leaks or floods – no more mould, musty smell or rotting floor joists.

Bowing Foundation Wall Threatens Home in Gooderham, Ontario

Bowing Foundation Wall Threatens Home in Gooderham, Ontario Bowing Foundation Wall Threatens Home in Gooderham, Ontario

When you picture a wall, specifically a foundation wall, you get a petty clear picture in your mind. We imagine foundation walls as perfectly straight, and typically made of concrete blocks or poured concrete, but this isn’t always the case. Nature loves to toy with foundations, and expansion and contraction can often lead to cracking and bowing. 

A homeowner in Gooderham, Ontario, learned just how much foundation walls could bow. Her home is close to 60 years old and built on a block foundation, but in recent years she has noticed her basement wall bowing more and more. 

The customer already had exterior work done on the upper portion of the wall and wanted to have the interior part fixed at the same time. Unsure who to turn to, she reached out to Clarke Basement Systems. 

System Design Specialist Robert Langton met with the worried homeowner and explained her options. She was happy to hear we had a solution for her basement, and a date was set to complete the repair. 

Foreman Dave Jackson used our CarbonArmor® Wall Repair System to straighten the bowing walls. CarbonArmor® is ten times stronger than steel and is flexible, contouring perfectly to the foundation wall. ArmorLocks® then attach the CarbonArmor® strips to the floor joist, permanently straightening the wall.

The customer is smiling ear to ear now that her basement walls are straight. She knows her home and is stable and safe, and she can continue to do exterior work without any worries.

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Gooderham 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.
