Concrete Group of Lakeland injects epoxy into vertical cracks and cuts out and patches spalled or hollow concrete, so the slab keeps its footing and the repair is sized to the damage.
What signs mean you need concrete repair and restoration?
Vertical cracks wider than a hairline, spalled concrete that shows reinforcing steel, and hollow-sounding patches are the signs. Exposed steel is the clearest one, because it means the damage is structural and not cosmetic. Concrete Group of Lakeland confirms the extent by tapping the slab with a concrete-sounding hammer before recommending a repair.
Solid concrete rings under the hammer. A dull, hollow sound means the top layer has lost its bond with the slab below, even when the surface looks fine. Concrete Group of Lakeland marks every hollow area, then sorts the damage: a vertical crack gets epoxy injection, and a spalled or delaminated area gets cut out and patched.

How does Concrete Group of Lakeland scope the job and what drives the price?
Structural spalling repair with exposed reinforcing steel is priced at $7 to $13.50 per square foot. The final figure moves with how much area is spalled and which repair method the damage calls for.
We measure every affected square foot after the tap survey, since hollow concrete often reaches past the visible damage. Epoxy injection on a crack and a sawcut patch on a spall are different jobs with different labor, so a slab with both is quoted for both. A driveway also brings a city permit into the scope, covered under the timeline below.
What are the steps of the job, start to finish?
Concrete Group of Lakeland marks the damage, saws clean edges around any patch, prepares the concrete, then injects epoxy or places patch material and cures it per the product instructions. Cracks and spalls get different methods, so a single job can include both on the same slab.
For a patch, the concrete saw and sawcutting blades cut the perimeter so the repair has defined edges and the loose concrete comes out. We bring the prepared concrete to a saturated-surface-dry condition, so the old slab doesn't pull water out of the new material. Then we place the repair material, consolidate it, finish it, and cure it according to the material instructions.
For a vertical crack, we pressure-inject epoxy starting at the lowest port. When epoxy emerges at the next port up, we move to that port and continue, so the crack fills from the bottom.
How long does the repair take to complete?
Three things set the schedule: the size of the repair area, the cure time of the material, and whether the work needs a permit. Cutting and placing are the short part; curing sets the pace. Concrete Group of Lakeland gives a schedule once the slab has been tapped and measured, and keeps traffic off until the material has cured per its instructions.
Driveways are on the city's list of work that requires a permit, and Lakeland currently works under the Florida Building Code, Eighth Edition (2023). On a driveway repair, permit lead time comes before any cutting. Lakeland gets a light freeze only now and then in winter, and on those mornings we wait to place material until it warms.
What Goes Into the Work
In plain terms, the job can include:
- Remove unsound concrete; use a smaller chipping hammer for final removal near reinforcing steel.
- Where reinforcing bars are corroded, expose the affected bars fully and leave clearance beneath them for repair material.
