Should You Repair or Replace Concrete? The Signs That Decide It

Stable concrete with small, isolated damage can be repaired. Major settling, wide cracks in many places or sections breaking apart mean it is time to replace it.

Free, no-obligation estimates. We look at the slab and tell you plainly which fix will last.

Start with the slab

When concrete can be repaired

Concrete is worth repairing when it is mostly stable and the damage is isolated: small cracks, minor chips or a worn surface.

That means the slab still sits where it was poured and the trouble stays in one place. We patch the crack, fill the chip or renew a worn or flaking top, the flaking the trade calls "spalling", and the rest of the slab keeps doing its job. Concrete Network: Concrete Repair walks through how damage like this is judged.

A repair is the right call when all of this is true:

  • The slab is mostly stable and level
  • The damage stays in one spot
  • It is small cracks, minor chips or surface wear

When a repair will not last, replacement is the better choice, and we tell you so on the estimate rather than patch it twice.

When it has to go

Signs concrete needs replacing

Major settling, wide cracks in many places and sections breaking apart all point to replacing the concrete, not repairing it.

These are the signs of a slab past repair:

  • Major settlingThe slab has sunk well out of level, not just a small lip at one joint.
  • Wide cracks in many placesNot one crack to patch, but wide ones running across the slab.
  • Sections breaking apartPieces have broken loose and the slab no longer holds together.
  • Large areas that have shiftedOn a driveway, big shifting areas or damage across the whole slab usually call for a new one.

Only part has failed

Partial replacement and color matching

When only some sections have failed and the rest are sound, we replace just the failed sections and leave the good ones where they are.

The catch is how it looks. New concrete always comes out lighter than the old, so matching the color and texture is hard, and the new section will show against the old. On a side yard or a back walk that is often a fair trade for the savings; on a patio or a front driveway you look at every day, it is worth talking through before we cut.

A new top, the same slab

Resurfacing as the middle option

Resurfacing suits concrete that is structurally sound but looks old and worn.

Instead of tearing the slab out, we bond a thin new top layer over it, the trade's "overlay". It takes care of a tired, stained or flaking surface. It does not fix a slab that has settled or is breaking apart, so the replacement signs above still decide.

Past a patch

Other ways to fix a failing slab

A sunken slab is often raised in place, while a slab past saving comes out and is replaced with new concrete. One keeps the slab you have; the other starts over on solid ground.

Whichever it turns out to be, this is how we handle it:

  • Free, no-obligation estimates
  • We quote the whole job before we start, with no surprise charges after
  • We show up when we say we will
  • We clean up when the work is done

Lifting a sunken slab instead of replacing it

Lifting a sunken slab back to level can cost far less than tearing it out and replacing it, as long as the concrete is in good condition.

The trade calls it "slabjacking" when grout or slurry is pumped underneath to raise the slab, and "polyjacking" when foam does the lifting. A slab with too many cracks may need replacing instead.

Replacing with new concrete

Replacement takes out the failed concrete, fixes what made it fail and pours new concrete on a compacted base.

Before anything new goes in, we deal with the cause, whether that is roots, poor compaction or drainage, so the new slab does not go the same way as the old one.
