Concrete leveling
Driveway Leveling in Rockford, IL
A driveway is the largest slab most homes have and the one that carries actual weight, so when the ground under it gives way the drop shows up fast and keeps going.
Cause
Why This One Settles
Driveways fail at the apron and at the street first, because both ends sit against something that was backfilled rather than on undisturbed ground.
- The apron at the garage sits on ground that was dug out and refilled during construction. Backfill keeps compacting for years after the pour.
- The street end sits over the utility trench. Every buried line under a driveway is a strip of soil that was disturbed once and never got the decades of settling the rest of the lot had.
- Water running off the roof and down the drive finds the joints and washes fines out from under the slab, which is how a small void turns into a big one.
- Vehicle weight does not cause the void, but it is what makes an existing one show up as a visible dip rather than a hairline crack.
The underlying reason any of it moves here is the frost line. Rockford requires footings at 42 inches because the ground freezes that deep, and flatwork is poured well above it. Full explanation on why concrete sinks in Rockford.
The work
How This Job Runs
- Step 1
Walk the drive and mark every panel that has moved, not just the obvious one. Panels move in groups.
- Step 2
Drill injection holes, roughly penny-sized, spaced across the low area.
- Step 3
Inject in stages, watching the slab with a level as it comes up rather than filling to a number.
- Step 4
Stop at grade, patch the holes, and clean the surface.
When lifting is the wrong call
Where This Does Not Work
If a panel is broken into several pieces rather than settled as one, lifting it just spreads the cracks. A slab has to be structurally intact to be worth raising, and a cracked-through panel is usually a replacement of that panel only, not the whole drive.
Cost
What It Runs
Most driveway work lands in the $500 to $3,000 range depending on how many panels moved and how far they dropped.
Full per-square-foot breakdown and the comparison against replacement is on the pricing page, and the method choice is covered on mudjacking versus foam.
