When the top of the slab starts letting go
Spalling and scaling are what it looks like when the surface of the concrete fails — flaking, peeling, and breaking away to expose the aggregate underneath. It is one of the most common conditions on central-Indiana commercial property, and it is progressive: once the surface skin is gone, water and salt reach deeper, and what was a cosmetic blemish at a retail entrance becomes a rough, deteriorating, claim-prone surface.
We restore spalled and scaled commercial surfaces across Hamilton County and, just as importantly, address what caused them so the repair is not eaten away the following winter.
Why surfaces fail here: freeze-thaw plus chemistry
The central-Indiana surface story is a combination. Dozens of freeze-thaw cycles a winter drive water into the surface pores, freeze it, and pop the surface apart. De-icing salts accelerate it chemically and by increasing how often the surface cycles through freezing. And where the original concrete was finished poorly — overworked, sealed wrong, or placed without adequate air entrainment — the surface had little resistance to begin with. Read together, those tell us whether a surface can be restored or is destined to keep scaling.
Repair, resurface, or replace
Spalling is a spectrum, and the right answer depends on how deep it goes:
- Shallow scaling and pop-outs — patch and restore the affected areas
- Widespread surface loss on a sound slab — a bonded overlay or resurfacing to give a new wearing surface
- Spalling that has reached reinforcement or undermined the slab — partial or full replacement
- Honest triage so you are not overlaying a slab that needs replacing, or replacing one that only needs resurfacing
Fix the cause, not just the surface
Restoring a surface without addressing why it spalled is a short-term repair. Where it applies, we pair the restoration with cause control: a quality penetrating sealer to slow water and chloride intrusion, drainage correction so meltwater is not sitting on the surface, and guidance on de-icing practice so aggressive chlorides are not poured onto vulnerable concrete every storm. That is the difference between a surface that holds and one that re-scales.
Where it matters most
Spalling shows up first and worst exactly where it is most visible and most consequential — building entrances, plaza and walkway surfaces, parking-structure decks, and the salt-soaked aprons by doors and drives. Those are the surfaces that shape how a property is perceived and where rough, broken concrete turns into a slip or trip complaint, so they are where we focus the restoration.
Scoping a surface restoration
Spalling pricing depends on area, how deep the surface loss goes, and whether the answer is patching, a bonded overlay, or partial replacement. Shallow scaling is inexpensive to restore; widespread surface loss needing an overlay, or spalling that has reached reinforcement, costs more because it is a bigger or deeper repair. Adding cause control — sealing and drainage correction — is a small line that protects the larger one.
The proposal line-items the surfaces by treatment so you can fund the visible, high-traffic entrances and walkways first and schedule the rest. We are candid about whether a surface is a restoration candidate or genuinely past it, so you are not overlaying a slab that needs replacing. The assessment is free, and it includes the sealing-and-drainage recommendations that keep a restored surface from re-scaling next winter.
