Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Algonquin Highlands 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.

  • Uneven Patios
  • Sinking Sidewalks      

  • Uneven Concrete
  • Sunken Pool Decks

Stabilizing and Waterproofing a Cottage in Algonquin Highlands, ON

Brad N. noticed that his cottage began flooding due to the proximity to the lake. He also realized that one of the walls started bowing. To improve the structural integrity and basement of his cottage, Brad contacted Clarke Basement Systems for a solution.

The solution provided included our patented DryTrak® Interior Basement Drainage System for Monolithic Foundations, TripleSafe™ Complete Sump Pump System and CarbonArmor® Wall Solution. The DryTrak® and TripleSafe™ worked together to ensure that any unwanted water from flooding would be drained away from the cottage, thus keeping the basement dry.
