Jacking, Slabjacking, Lifting, Leveling — All One Service

The vocabulary confuses people, and contractors don't help by each using a different word. Mudjacking is the original technique: drill 1–2 inch holes, pump a cement-and-soil slurry underneath, hydraulic pressure raises the slab. Concrete jacking and slabjacking are trade shorthand for the same thing.

Concrete lifting and concrete leveling are the modern, plainer names and cover both mudjacking and the newer method, polyurethane foam injection — 5/8 inch ports, a two-part expanding foam, full strength in about 15 minutes.

So when you compare quotes, the word on the page tells you nothing. The question worth asking is which material is going under your slab, because that is the actual difference in price, weight and durability.

Which Method for a North Fulton Slab?

Mudjacking costs $3–$5 per square foot. It is proven and economical, and it is fine where the base beneath is genuinely stable.

Foam costs $5–$8 per square foot and is usually the better answer in Alpharetta specifically. Slurry is heavy, and the ground under most settled slabs here is uncompacted fill that has already demonstrated it cannot carry what is on it — adding several hundred pounds of cement slurry to that is working against yourself. Foam weighs a fraction as much, is closed-cell and waterproof so it won't wash out, and can be topped up cheaply at a single port if the fill continues to move.

Why Newer Alpharetta Homes Have Sinking Driveways

It reads as a paradox — the house is twenty years old and the driveway is falling apart — but new construction is the risk factor, not a protection against it. Alpharetta's expansion from the 1990s onward built on lots that were cut and filled to create level pads. Fill placed and compacted properly in thin lifts is stable. Fill placed quickly is not, and it keeps densifying under its own weight for five to ten years.

The house is unaffected because its footings pass through the fill onto competent soil below. The driveway, patio and walkways sit directly on it and go down with it. That is why you so often see a structurally perfect north Fulton home with a driveway separating at the garage apron — and why pouring a replacement on the same fill reproduces the problem within a few years.

Cost in Alpharetta

$3–$8 per square foot: walkway panel $300–$600, sunken driveway section $400–$1,600, full two-car driveway $1,200–$4,500, patio $700–$3,000. Replacement across north Fulton is $8–$15 per square foot. Where a slab qualifies for lifting, the saving is 50–70%. If yours doesn't qualify, our concrete repair page covers the alternatives.

Permits and HOA Approval

No City of Alpharetta permit is needed to level an existing slab — it is repair, not construction. Two things do apply: right-of-way work between your property line and the street needs City approval, and a large number of Alpharetta subdivisions have architectural review covenants that cover visible exterior work. Leveling rarely triggers the latter since the finished appearance is unchanged, but it is worth a check with your HOA before scheduling.

Frequently Asked Questions

What's the difference between jacking, slabjacking, lifting and leveling?

Nothing — four names for one job. Compare the material going under the slab, not the term on the quote.

How much does concrete lifting cost in Alpharetta?

$3–$8 per square foot. Two-car driveway $1,200–$4,500 against $8–$15 per square foot to replace.

Why do Alpharetta driveways sink if the houses are new?

Cut-and-fill lots. The footings reach competent soil; the driveway sits on fill that's still consolidating.

Is lifting better than replacing?

On fill, decisively — a new slab on still-settling ground repeats the problem. Replace only when the concrete itself has failed.

Do I need a permit in Alpharetta?

No for the leveling itself. Right-of-way work needs City approval, and check your HOA's architectural covenants.
