Concrete repair: cracks, scaling, broken steps and slabs in Connecticut
Free assessment. We tell you whether to repair, resurface or replace, and why.
- Repair first when the concrete underneath is sound
- Overlays only over slabs that haven't moved
- Foundation crack injection for leaks
Repair methods we use
Connecticut is hard on concrete. Salt and freeze-thaw flake the surface off (scaling), pop out chunks (spalling) and open every crack a little more each winter. Settled slabs tip toward the house and trip people.
Not all of it needs replacing. If the slab underneath is sound and hasn't moved, a repair or resurfacing costs a fraction of a new pour. If it has moved, a surface fix is money wasted, and we'll tell you that up front.
- Crack sealing
- Cracks routed and filled with flexible sealant so water stays out
- Patching
- Spalls cut back to sound concrete, rebuilt with polymer-modified repair mortar
- Resurfacing
- A thin cement-based overlay over a scaled but solid slab
- Step nosings
- Broken edges formed and rebuilt, pinned into the old step
- Lifting
- Sunken panels raised with foam or slurry; see concrete leveling
- Crack injection
- Polyurethane or epoxy injected into foundation wall cracks
- Panel replacement
- Sawcut out and re-poured when a section is beyond repair
- A
- Scaling: surface flaking; resurface if the slab below is sound
- B
- Spalling: cut back to sound concrete and patch; rusting steel treated
- C
- Settlement: lift or replace; a patch won't hold
How the job goes
Assess
We look at what failed and why: salt, water, settlement or overload. The cause decides the fix.
Recommend
Repair, resurface, lift or replace, with a price for each where more than one makes sense.
Prep
Grind, sawcut or clean back to sound concrete. Repairs fail when this step is rushed.
Repair
Material matched to the depth and the job, placed and finished.
Cure and protect
Cured properly, and sealed where it helps keep water and salt out.
Planning prices
| Work | Planning range | What drives it |
|---|---|---|
| Rout and seal cracks in walks, drives or slabs | $4–$9 / linear ft | Small jobs carry a minimum |
| Resurface a sound but scaled slab (overlay) | $5–$10 / sq ft | Only works if the slab hasn't moved |
| Rebuild broken step nosings and corners | $600–$2,500 | Per set of steps |
| Lift a sunken walk or driveway panel | $600–$1,800 | Typical one-to-three panel job |
| Foundation crack injection | $600–$1,500 per crack | Interior injection on poured walls |
Planning ranges for Connecticut in 2026, not quotes. Ledge, tight access, long pump or wheelbarrow runs and very small pours push a job up. Your price comes in writing after we've seen the site.
Common repairs
- Scaled driveways and walks
- Resurfacing over a sound slab, or replacement if the scaling runs deep.
- Broken steps
- Nosings and corners rebuilt; replacement when steps have pulled away. See concrete steps.
- Garage floors
- Cracks, spalls and pitting repaired, and resurfacing before a coating.
- Foundation cracks
- Interior injection to stop leaks. See foundations.
- Commercial walks and curbs
- Trip hazards, broken curbs and spalled ramps. See commercial concrete.
- Sealing
- Penetrating sealer to slow down future salt damage.
What damages concrete in Connecticut
Scaling is the surface flaking off in thin layers, usually from deicers and freeze-thaw on concrete that wasn't air-entrained or was finished with extra water. Resurfacing works if the concrete below is sound.
Spalling goes deeper: chunks breaking off, often over rusting reinforcement or at edges hit by plows and shovels. Patches have to go back to sound concrete.
Settlement is the slab itself moving, usually because water washed out or softened the base. Lifting or replacement fixes it; a patch doesn't.
Deicers. Fertilizer-type deicers with ammonium nitrate or ammonium sulfate cause a lot of the damage we see. Rock salt in moderation and sand for traction are kinder.
Questions we hear about concrete repair
Can scaled or flaking concrete be fixed?
Yes, if the concrete under the scaling is sound. We grind off loose material and apply a cement-based resurfacer. If scaling is deep, or the slab is cracked and moving, replacement is the better buy.
Is resurfacing worth it?
When the slab is level and solid, yes: it costs a fraction of replacement and gives you a new wearing surface. Over a slab that's cracked through or settling, the overlay cracks with it.
Why do concrete patches keep failing?
Usually because the patch went on dirty or weak concrete, was feathered too thin at the edges, or used the wrong material. A lasting patch has square-cut edges, sound concrete underneath and a mortar meant for the depth.
Repair or replace: how do you decide?
Movement decides most of it. If the concrete hasn't settled or heaved and the damage is at the surface, repair. If it's tipping, cracked through, or holding water against the house, replace or lift.
Can you repair my garage floor?
Yes: crack filling, spall patching and resurfacing, including prep for an epoxy or polyaspartic coating.
Do you fix foundation cracks?
Yes, by injection from inside to stop leaks. If a crack looks structural, we'll recommend an engineer before any repair.
