Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Concord 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

Job Stories From Concord, ON
Business Owner Needed a Reliable Drainage System, Concord, ON

A warehouse in Concord, Ontario needed to be able to wash cube vans without flooding the warehouse. They had no drainage in this area, and they needed a drain that would be strong enough to hold heavy loads of trucks and forklifts without being damaged.

The business owner called Clarke Basement Systems and spoke to Claude Mathieu who explained the solution we had and how the job would be done.  Don Clarke and the team installed Exterior steel TrenchDrain and a SuperSump sump pump system. The TrenchDrain captures the melting snow, slush, and water and drains it to the Supersump. The Steel TrenchDrain was use in the area that they would wash the trucks, capturing the water before it could do any damage to products in the warehouse.

The owner was happy because it saves time washing the trucks and there is no damage to inventory.
