Apex Concrete

Concrete Repair & Leveling in the Dayton area

Not every bad slab needs to be torn out. Settled but sound concrete can often be lifted back to grade and sealed for a fraction of replacement cost. We tell you plainly which of the two your slab is.

What repair work includes

  • Polyurethane slab lifting and void filling
  • Structural crack routing and epoxy injection
  • Overlay resurfacing for spalled but sound slabs
  • Honest replace-vs-repair assessment

How we decide between lifting a slab and tearing it out

The question is whether the concrete itself is still sound. A slab that has settled in one piece over a void — common where backfill around a foundation or a utility trench has consolidated — can usually be lifted back to grade. A slab that is broken into several pieces, spalling down past the surface, or sitting on a base that keeps washing out has failed as a structure, and lifting it only buys a season. We tell you which one you have and why.

What slab lifting actually involves

Penetrations about the width of a dime are drilled through the slab, and expanding polyurethane is injected underneath. It fills the void first, then lifts, and the rate is controlled by watching the surface against a level line. The holes are patched, and the surface takes traffic the same day rather than after a week of curing. It is not a cosmetic fix — the void that let the slab drop is gone, which is the part that stops it happening again.
