A crack is a symptom — the question is of what
Cracks are the most common and most misread concrete defect on a commercial property. Some are harmless shrinkage that will never move again; others are the visible edge of a structural or base problem that will keep opening until it is addressed. Sealing them all the same way is how money gets wasted — caulking a moving structural crack does nothing, and over-engineering a dormant hairline is just as pointless.
We repair cracks in commercial slabs, walls, and pavement across Hamilton County, and the first thing we do is figure out which kind you actually have before we quote a method.
Structural, non-structural, active, dormant
We sort cracks along two axes. The first is structural versus non-structural: does the crack compromise the slab's ability to carry load, or is it a surface and serviceability issue? The second is active versus dormant: is the crack still moving with load or temperature, or has it stabilized? A dormant non-structural crack can simply be sealed against water. An active structural crack needs the underlying cause — base movement, overload, missing control joints — addressed, or any repair will reopen.
The right method for the crack in front of us
Method follows diagnosis. We carry the full range so we are not forcing one approach onto every crack:
- Epoxy injection to structurally re-bond and restore load transfer across a sound, dormant crack
- Polyurethane injection to seal and stop water movement through active or wet cracks
- Rout-and-seal to widen, clean, and flexibly seal surface cracks against water and de-icer
- Stitching and stabilization where a crack needs mechanical reinforcement across the break
Cracks are how water gets in — and water is the real enemy
In central Indiana, an open crack is an invitation for the freeze-thaw cycle to do its worst. Water enters, freezes, expands, and levers the crack wider every winter, while below the slab that same water erodes and softens the base. A crack sealed promptly is cheap insurance; the same crack ignored for two seasons becomes a spalled, faulted, water-undermined repair that costs many times more.
Documented, and monitored where it matters
We document crack repairs with location and method, and for cracks we judge to be potentially active, we can establish simple monitoring so you know whether movement has truly stopped. That record tells you — and an engineer or owner, if one is involved — whether a slab is stabilizing or whether something larger is developing underneath it.
What determines the crack-repair approach and cost
Crack pricing is set by the method the diagnosis calls for, the total length, and access. Rout-and-seal of surface cracks is economical; structural epoxy injection and stitching of active cracks cost more because they restore load transfer and require precise work. The bigger cost variable is whether the cause has to be addressed — a moving crack over a failing base is a base scope as much as a crack scope, and we are clear about that distinction before you commit.
The proposal line-items the cracks by method and, where movement is suspected, includes monitoring so you are not paying to seal something that needs a structural answer. The assessment is free, and it sorts the cosmetic shrinkage cracks you can leave from the ones worth treating now before water and freeze-thaw widen them. That triage keeps a crack scope from quietly becoming a replacement.
