Concrete Repair in Kansas City
Kansas City Concrete Contractors repairs cracked, spalled, settled, and broken concrete for homes and commercial properties across the KC metro, and tells you plainly when a repair will hold and when replacement is the better investment.
What Kinds of Concrete Damage Do We Repair?
We repair the six problems behind most concrete damage in Kansas City: cracks, spalling and scaling, settled slabs, trip hazards, failed joints, and broken edges. Each one looks different and starts for a different reason, and the cause decides the fix.
Cracks
Hairline shrinkage cracks are normal. Cracks that widen, run through a full panel, or leave one side higher than the other are not.
Most structural cracks here start with clay soil swelling and shrinking under the slab, and water in the crack widens it every winter.
Spalling & Scaling
Scaling is the thin top layer flaking away. Spalling is deeper pieces breaking out, sometimes exposing stone or reinforcement.
Freeze-thaw cycles and de-icing salts drive most of it, especially on concrete that was not air-entrained or was over-finished with water at the surface.
Settled or Sunken Slabs
A panel that has dropped below its neighbors, often beside a downspout, a utility trench, or the garage apron.
Soil under the slab washes out or compacts after water finds a way in through open joints or poor drainage.
Trip Hazards & Heaved Edges
A raised lip between panels on a sidewalk, walkway, or entrance that catches shoes, carts, and wheelchairs.
Tree roots and frost heave lift one side of a joint while the other stays put.
Failed Joints
Missing or cracked sealant, crumbling joint edges, or panels that move independently of each other.
Sealant that was never maintained lets water reach the base, which is how a small joint problem turns into settled panels.
Broken Edges & Approaches
Crumbled slab edges along a driveway, broken approaches at the street or garage, and cracked corners.
Tires riding off an unsupported edge and slabs poured too thin at the approach cause most of these.
Should Concrete Be Repaired, Resurfaced, or Replaced?
It depends on whether the slab and the base under it are still sound. If both are sound and the damage is local, repair it. If the slab is sound but the surface is worn, resurface it. If the base has failed or the damage is widespread, replace it.
We make that call by answering five questions on site. Is the slab structurally sound, or does it rock, move, or sound hollow when tapped? Is the base underneath intact, or has soil washed out or settled? How much of the area is damaged: one panel, or most of them? How old is the concrete, and has it already been repaired? And is water still getting in? A repair that ignores the last question tends to fail.
Resurfacing is only the right answer when the slab underneath is sound. For worn, scaled, or stained concrete that is still solid, our concrete resurfacing and overlays restore the surface without removal. When the slab itself is failing, a new top layer will crack along with it.
| Condition | Usual Fix | Why |
|---|---|---|
| Isolated crack, panels still level | Repair | The base is sound. Sealing the crack keeps water from widening it. |
| Surface scaling or light spalling on a solid slab | Resurface | The damage is only at the surface, so an overlay restores it without removal. |
| One or two settled panels, still in one piece | Lift or replace the panel | The problem is local. The surrounding concrete is fine. |
| Trip hazard at a single joint | Repair | Removing the lip fixes the hazard without disturbing sound concrete. |
| Failed or missing joint sealant | Repair | Cleaning and resealing keeps water out of the base. |
| Cracks across many panels, slabs that rock underfoot | Replace | The base has failed. Any surface fix will crack again. |
| The same area repaired more than once | Replace | Repeated failure means the cause is below the slab. |
| Water ponding against the building | Replace with corrected slope | Drainage cannot be corrected on top of the wrong grade. |
When Is Concrete Replacement the Right Call?
Replacement is the right call when the base has failed, cracking is widespread, or earlier repairs keep failing, because no surface repair can fix what is happening underneath. Replacement does not always mean the whole slab: often only the failed panels come out, cut back to the nearest joints.
- →Tear-out. Sections are saw-cut to clean joint lines, broken out, and hauled away, leaving the sound concrete undisturbed.
- →Base correction. Soft or washed-out soil is dug out, new base rock is placed and compacted, and the grade is set so water drains away from the slab and the building.
- →New pour. Air-entrained concrete with reinforcement and joints sized to the use, doweled into adjoining slabs where vehicles cross the joint.
Not Sure Whether to Repair or Replace?
A site visit answers it. You get a written estimate that explains the recommendation.
How Do We Handle Commercial Concrete Repair?
We fix the failures that create liability and downtime first, such as trip hazards at entrances, failed panels in drive lanes, and broken loading areas, and we phase the work so the property stays open.
Commercial repair is a different job from residential repair. Slabs carry delivery trucks and forklifts, tenants and customers need access every day, and a raised panel at the front door is a liability question as much as a maintenance one. Repairs are priced panel by panel so you can see exactly what is being fixed and why, and they fit into the broader commercial concrete services we provide across the metro.
Parking Lots
Failed panels in drive aisles, around storm drains, and at dumpster pads are saw-cut at the joints and replaced on a rebuilt base. When failures are widespread, a full parking lot replacement is often the better long-term spend.
Trip Hazards & Liability
Raised panels at entrances, along storefronts, and on accessible routes are the repairs that expose a property to claims. We remove the hazard, record what was fixed, and give you the details for your files.
Failed Joints
Resealing joints on a schedule is the simplest way to extend the life of a concrete lot. Open joints let water under the slab, and panel failures follow.
Loading Areas & Dock Aprons
Truck traffic breaks down thin or under-reinforced aprons first. Replacement sections are poured at 8 inches with added rebar, the same standard we use on new loading areas.
Warehouse Floors
Spalled joint edges under forklift wheels, cracked panels, and uneven slabs at dock doors. Interior repairs run year-round, and our warehouse floor repair and replacement work is phased around shipping.
Phased Work
Repairs are sequenced by area so entrances, fire lanes, and loading docks stay usable. Where operations cannot pause during the day, the work moves to nights or weekends.
Which Home Concrete Repairs Do We Handle Most Often?
Driveways, sidewalks, patios, steps, retaining walls, and pool decks account for most residential repair calls. Each has its own page for when a repair turns into a replacement.
Driveways
Cracked and settled driveway panels, broken approaches, and crumbling edges. When the damage covers most of the slab, see our concrete driveway replacement work.
Sidewalks & Walkways
Heaved and sunken sections are usually replaced one panel at a time. Our sidewalk and walkway repair page covers city requirements and replacement details.
Patios
Settled patio slabs pull away from the house and tilt water toward the foundation. Isolated panels can be replaced; a patio that has settled as a whole usually needs a new base and pour.
Steps
Broken nosings, crumbling treads, and steps pulling away from the house. Minor damage can be repaired; steps that have shifted as a unit usually need to be rebuilt on a proper footing.
Retaining Walls
Leaning, bulging, or cracked walls are usually a drainage problem behind the wall. Our retaining wall repair and rebuilding work starts by finding where the water is going.
Pool Decks
Cracked deck panels, failed joints at the coping, and worn surfaces. For worn but solid decks, see our pool deck resurfacing options.
Can a Sunken Concrete Slab Be Lifted Instead of Replaced?
Often, yes. A settled slab that is still in one piece can often be lifted back to grade instead of torn out, and the site visit tells you whether yours qualifies.
Lifting works when the slab is intact and the ground beneath it has stabilized. It is not the right fix for a slab that has broken into pieces, a panel that keeps dropping because water is still washing out the soil, or concrete that was too thin to begin with. In those cases, replacing the section on a corrected base is the repair that lasts.
How Does a Concrete Repair Job Work?
A repair runs in five steps: a site visit, a diagnosis of the cause, a written estimate, the repair itself, and cure time before the area goes back into use.
Site Visit
We look at the damage in person: the extent of cracking, whether panels move or sound hollow, the condition of joints, and where water goes when it rains.
Diagnosis
We identify the cause, not just the symptom. A crack caused by a failed base needs a different fix than a crack caused by a missing joint.
Written Estimate
You receive a written estimate that lists what will be repaired, resurfaced, or replaced, why, and the expected return-to-service timing.
The Repair
Damaged sections are saw-cut to clean lines, the base is corrected where needed, and new concrete or repair material is placed and finished to match the surrounding surface.
Cure & Return to Service
Replaced sections are new concrete: foot traffic is typically fine after 24 to 48 hours, and vehicles should wait about 7 days. Sealant and crack repairs return to service sooner.
What Does Concrete Repair Cost in Kansas City?
Repair cost depends on the size of the damaged area, whether the base needs work, access, and the finish that has to be matched, so every job is priced after a site visit rather than from a list.
For budgeting a full driveway replacement, our Kansas City driveway cost guide walks through what goes into the number. For damage that is worth acting on before it spreads, see five signs your concrete needs repair.
Size of the Damaged Area
Sealing a few cracks and replacing several panels are very different jobs.
Condition of the Base
If the soil or base rock under the slab has failed, it has to be dug out and rebuilt before new concrete goes down.
Removal & Haul-Off
Saw-cutting, breaking out, and hauling old concrete is part of every replacement.
Access
Backyard patios and tight commercial sites take more handling than an open driveway.
Finish Matching
Broom finishes are straightforward; stamped, colored, or exposed aggregate surfaces take more work to match.
Scheduling Requirements
Night, weekend, or phased work on a commercial property changes the labor plan.
