PolyLevel™ Concrete Leveling & Lifting

The sunken and cracked concrete around your Philadelphia County 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 mudslurry instead of foam. Mudslurry 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        

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

Job Stories From Philadelphia County, PA
BQ Saves Plumbing Business from Collapsing

The owners of a Manayunk plumbing business in Philadelphia began experiencing issues with opening their windows and doors due to their cracked foundation. They noticed a large crack forming in the wall that connected their garage door to the building itself. The crack in the foundation was causing the building to sink, and needed immediate stabilization in order to save the building from completely collapsing. They reached out to us after seeing one of our "cracked foundation" yard signs and then scheduled a free estimate to determine how bad the problem actually was. 

After a representative visited the Manayunk business and performed an estimate, he was able to determine that the crack in the wall was causing the business to substantially sink, therefore making it difficult to open windows and doors. He proposed that the best solution for this problem was to insert a push pier system in the wall which would close the crack and stabilize the foundation back to where it originally once was. Four push piers were inserted into the wall, and in just a few days the foundation was stabilized. Since the push pier install, the owners of this Manayunk plumbing business have had fully functioning windows and doors, and the foundation has stopped sinking. Using our push pier system we were able to stabilize the foundation, and save a Manayunk plumbing business from collapsing.
