Concrete slab cracking, settling, heaving, and slab-jacking — diagnosed and repaired by local crews.
Slab Repair Overview
Slab repair covers cracking, differential settlement, heaving, and uneven sections — both in homes built on slab and in attached concrete (driveways, patios, garage floors). The fix depends entirely on what caused it.
Common slab situations in Middle TN
Slab issues in the Murfreesboro area come from a predictable mix of clay-soil movement, drainage, and original construction quality. Patterns we see most often:
- Hairline shrinkage cracks from original cure — usually cosmetic only
- Wider, growing cracks tied to active soil movement underneath
- One corner of the slab dropping where downspouts dump water against the foundation
- Center sections heaving upward in expansive clay during wet seasons
- Plumbing leaks under the slab that wash out fill and create voids — common in 1960s–1980s homes
- Uneven garage floors from poorly compacted fill or freeze-thaw under the apron
- Cracked tile or hardwood floors above slab cracks that telegraph through
- Sloped or sinking driveway and patio sections
How slab repair is typically done
- Assessment. Visual walkthrough plus elevation readings to find low and high spots. Sometimes a leak detection company is brought in if a plumbing leak is suspected.
- Diagnosis. Determine cause: drainage, soil movement, plumbing, or original construction. The repair scope hinges on this.
- Plan. Written scope: crack injection, slab-jacking (mudjacking or polyurethane), pier installation under the slab edge, drainage work, plumbing repair sequence.
- Repair. Inject cracks, lift sections back to level, install piers if needed, address drainage. Plumbing leaks must be fixed before the slab is lifted.
- Verification. Re-measure elevations, confirm no further movement, document the work.
What it usually costs in Murfreesboro
Crack injection runs $500–$2,000. Slab-jacking a sunk section (driveway, patio, garage floor) usually lands at $900–$3,500. Larger interior slab lifting with piers can reach $8,000–$20,000+. See our foundation repair cost guide for the full breakdown.
Warning signs that need attention now vs. can wait
Call this week:
- Cracks that have widened or extended in the last 6 months
- Visible vertical displacement (one side of a crack higher than the other)
- Doors that suddenly bind or scrape
- Wet spots on the floor that never dry — possible plumbing leak under the slab
- Tile or hardwood lifting / cracking along a clear line
- Water pooling against the foundation after every rain
Monitor and address with normal scheduling:
- Stable hairline cracks from original cure
- Minor surface spalling on a driveway
- Cracks that haven’t changed in years
What we ask when you call
- Where is the slab issue — interior floor, garage, driveway, patio?
- How long have you noticed it and is it changing?
- Have you seen any unexplained moisture on the slab or in the surrounding area?
- Has water bill spiked or has the water meter been spinning with everything off (sign of slab leak)?
- How old is the home and what’s the floor finish above the slab?
- Photos help — wide shot plus a tape measure across the crack.
Frequently asked questions
What’s the difference between mudjacking and polyurethane lifting?
Mudjacking pumps a cement slurry under the slab — cheaper, heavier, takes 24–48 hours to cure. Polyurethane foam lifting is faster, lighter, and cures in minutes — costs more but works in tighter spaces.
Can a cracked slab be repaired without removal?
Almost always, yes. Tearing out and re-pouring is rarely the right answer for residential slabs — crack repair, slab-jacking, and edge-pier work are usually more cost-effective.
Is a hairline crack a problem?
Usually not. Most slabs develop a few hairline cracks during the first year as concrete cures. Watch for changes — width, vertical displacement, or moisture seeping through.
Will lifting damage my floor finish?
For interior lifts, the lifting itself is gentle, but tile, grout, and brittle finishes sometimes crack. Crews usually warn you up front if a floor finish is at risk.
Do you serve areas outside Murfreesboro?
Yes — Smyrna, La Vergne, Eagleville, Christiana, Rockvale, Walterhill, Blackman, and the rest of Rutherford County. See service areas.
