Repair or Replace: Getting It Right
Concrete repair and replacement covers the problems South Bend winters leave behind: sunken walks, driveway panels that heave and drop, cracked and crumbling steps, and surfaces that have scaled away under salt. The hard part is not doing the work, it is choosing the right fix. Leveling or patching can save a lot of money on a sound slab. On a slab that is broken up or sitting on a failing base, the same repair just delays the bill. We look at the concrete and the ground under it and tell you which one makes sense.
Why concrete fails here
Lake-effect snow, an average of 64.5 inches a year according to Wikipedia's climate data for South Bend, keeps slabs wet through the winter. Water that gets under a slab or into its surface freezes and expands, lifting panels and breaking off the top layer. Spring melt can wash fine soil out from under a slab, leaving a void that lets it sink. Add decades of age, since South Bend's median home was built in 1955, and many slabs here have been through dozens of winters on a base that was never built for it.
Repair options
- Mudjacking (slab jacking): a cement-based slurry is pumped through small holes to fill voids and lift a sunken slab. HomeGuide lists $4 to $9 per square foot, with results that typically last 5 to 7 years with good drainage.
- Polyurethane foam leveling: lightweight foam is injected through smaller holes and expands to lift the slab. HomeGuide lists $8 to $25 per square foot and notes that foam often lasts longest because it adds little weight to weak soil.
- Crack repair: cracks are cleaned out and filled with a flexible sealant or repair material to keep water out.
- Resurfacing: a thin cement-based overlay over a sound but scaled or worn surface. HomeGuide lists $3 to $7 per square foot.
- Step repair: rebuilding broken edges and corners on otherwise sound steps.
When replacement is the better fix
- The slab is broken into many pieces
- Sections heave every winter, which points to a base or drainage problem leveling cannot fix
- Scaling covers most of the surface and is deep
- The slab is too thin or was never reinforced
- The slope sends water toward the house
Replacement means cutting out the failed sections at joints, removing them, rebuilding the base with compacted gravel, and pouring new air-entrained concrete. HomeGuide puts slab replacement at about $6 to $15 per square foot. Often we replace only the worst panels and leave the sound ones in place.
Fixing the cause
Every repair should also look at why the concrete failed. Common causes around South Bend homes:
- Downspouts emptying onto or beside a slab
- A yard graded toward the walk or driveway
- Tree roots lifting panels
- Salt use on young or poorly finished concrete
- No control joints, so cracks run wherever they like
We point these out and include the fix, such as extending a downspout or regrading a strip of lawn, so the new work does not fail the same way.
After the repair
Leveled slabs can usually be used the same day or the next. Replaced sections need the same curing time as any new concrete. Seal the repaired area and the slabs around it, keep water moving away from the concrete, and go easy on salt.

Concrete Repair & Replacement Questions
Is it cheaper to level concrete or replace it?
Leveling usually costs less. HomeGuide lists mudjacking at $4 to $9 per square foot against $6 to $15 for replacement. Leveling only makes sense if the slab is mostly intact.
How long does mudjacking last?
HomeGuide says mudjacking typically lasts 5 to 7 years with good drainage, and foam leveling often lasts longer.
Can scaled concrete be fixed?
Light scaling on a sound slab can be resurfaced. Deep scaling over most of the surface usually means replacement.
Why does my sidewalk keep heaving every winter?
Water under the slab freezes and lifts it. The fix is drainage and a proper gravel base, which usually means replacing the panel rather than leveling it.
Will new concrete match my old concrete?
Not exactly at first. New concrete is lighter and weathers toward the older color over time.
