This caving foundation wall in Lakefield, Ontario, was a significant concern for our customer. The primary worry was that the wall would cave in resulting in a costlier repair. To stabilize the wall our team installed CarbonArmor®, to secure the wall from any further movement. ThermalDry® Insulation was placed over the foundation of the walls to funnel any water or moisture collected into the WaterGuard® Below-Floor Drain. WaterGuard® was installed below the floor to capture groundwater seepage and help with the hydrostatic pressure. Both of these systems direct the water collected into the SuperSump® Premier Sump Pump System. By correctly assessing the issue our team was able to provide a permanent waterproofing solution for our customer.

We always need more space. Extra closet space, more cupboards, a bigger garage; the options are endless for additional space.

A customer in Bridgenorth, Ontario, was looking to add more storage at her cottage. She had an open crawl space below the building, but some of the sides were exposed, and it was a dirty, musty space most of the year. 

She reached out to Clarke Basement Systems and met with System Design Specialist Rob Malcomson. Rob designed an encapsulation system for the homeowner, and a date was set for the repair. 

Foreman Lucio Flores and his crew worked hard waterproofing the space. Drainage matting was used on the ground to help disperse water. ThermalDry® Wall Membrane was installed around the walls' perimeter to act as both an insulator and a vapour barrier. Lastly, CleanSpace® Vapour Barrier was placed on the walls and floor the help keep moisture from seeping in and giving the space a finished, clean look. 

The customer is looking forward to more storage space at her cottage. The entire family has room to store their toys now without filling the living space.

In Lakefield, Ontario, a pair of new homeowners had noticed their sump pump system going off frequently. The irritable sound had called for an investigation where they found that their block foundations were cracking and about to lean inward. They called Clarke Basement Systems right away to have this problem solved before matters got worse. Our System Design Specialist, Ryan Hanlon, visited the home for a further look. He diagnosed the issue as from all the constant pressure from the soil during the wet and thawing months, which aggravated the foundation, causing it to crack. His solution was to have our team install Carbon Armour. This material is a carbon fiber roll that, when placed on the cracked block foundation and covered with a mixed resin, hardens stronger than metal. Our installation Foreman, Alan Murphy, and Specialist, Andrew Latour, started the work. The results were impressive; even the handyman husband was blown away.

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Selwyn 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.

  • Cracked Driveways
  • Uneven Patios
  • Sinking Sidewalks      
  • Uneven Concrete
  • Sunken Pool Decks
  • Highway & Commercial Issues

We have an old cottage that has occasional leakage that we would like to have assessed
Project Location: Selwyn, ON
Crawl space at the above cottage location is in need of repair. Corner blocks are shifting out of place, parts of the walls are cracking. The offset on one wall was not tied in together properly and has opened up. There is also a large crack on the same wall. When the cottage was lowered onto the wall, the space between the foundation and the cottage was taken up with a number 2 by 6 on the flat. They placed the ends of the 2 by 6 over top of a vent and as a result the vent is pushing out.
