PolyLevel™ Concrete Leveling & Lifting

The sunken and cracked concrete around your Allentown 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 use mudjacking instead of foam. Mudjacking is heavier, requires 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      
  • Sinking Basement & Garage Floors   

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