PolyLevel™ Concrete Leveling & Lifting

The sunken and cracked concrete around your Bolton home is both an eyesore and a safety hazard. It is also likely to get worse, but we can fix it for you.

Our experts use PolyLevel, a superior polyurethane foam. Small holes are drilled in the concrete, the foam is injected and the expanding foam lifts the concrete. The majority of contractors you will call use mudjacking instead of foam. Mudjacking is heavier, require larger holes in the concrete and does not last as long as PolyLevel. Call us today to learn more.

We Fix
  • Cracked Driveways
  • Uneven Patios
  • Sinking Sidewalks      

  • Uneven Concrete
  • Sunken Pool Decks
  • Highway & Commercial Issues

Job Stories From Bolton, ON
TripleSafe Sump System Remedies Bolton, ON Basement’s Moisture Issue

Chris and Elvira T. were having trouble controlling their Bolton, ON basement’s moisture problem. Without effective drainage, their basement was flooding and causing them unnecessary headache. They reached out to the professionals at Clarke Basement Systems for help.


David Macdougall met with Chris and Elvira to analyze their basement’s predicament. After a comprehensive examination, David suggested the installation of the TripleSafe Sump System and the IceGuard Discharge Line Anti-freeze device. The combination of these two products would solve their drainage issues and prevent the cold weather from causing the drain lines to freeze. Primary Foreman Graham Gottschalk managed the installation of these products quickly and effectively, and Chris and Elvira were thrilled with the final result.
