Concrete Leveling Built for Harford County
Sunken sidewalks, driveways, and patios in Bel Air are almost always caused by voids or poorly compacted soil underneath the slab, not a bad slab. Our polyurethane foam injection fills those voids and lifts the existing concrete back to level in hours, not days.
Full Replacement / Mudjacking
- Days of jackhammering, dust, and blocked access
- Mudjacking pumps heavy cement slurry into already-failing soil
- Added weight can cause the same settlement to recur
- Slurry is water-sensitive and can wash out over time
- Higher material cost and disposal fees
Polyurethane Foam Injection
- Small injection holes, no demolition
- Cures in about 15 minutes; walk on it same day
- High-density foam adds minimal weight to the soil
- Hydro-insensitive, won't wash out or break down
- Stabilizes the base while lifting the slab
