Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Pefferlaw 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

  • Sunken Pool Decks

Job Stories From Pefferlaw, ON
A Little Funky in Pefferlaw, Ontario.

A customer in Pefferlaw, Ontario, was sick and tired of not using their finished basement. The basement was unusable because it was constantly plagued by musty odours caused by water seeping into the basement walls through the home's exterior perimeter. This customer wanted functional use of their basement and wanted to clear his mind of worry. So, Clarke Basement Systems installed a complete perimeter system backed by a 25-year warranty. This particular and unique perimeter system is a combination of patented and industry-leading technologies dedicated to keeping your basement dry and free of mould and mildew. After the water is drained and captured by the interior perimeter drainage, it is safely and efficiently pumped out of the home to the main drain using one of Clarke Basement Systems' extremely reliable sump pump systems. After Foreman Lucio Flores and his installation team were complete, the customer regained use of their basement space and could continue to remodel and renovate. More importantly, though, they no longer had to worry about more future damage to their beloved family home.
