Concrete Leveling in Marietta, GA

Marietta's concrete problem is an age-of-housing problem. Cobb County's established neighbourhoods went in between the 1960s and 1980s, and a great deal of that original flatwork is now settling — not because it was badly poured, but because it was poured to the base standards of its day. Leveling raises those slabs without replacing them. Call (770) 637-7481 for a free assessment across Marietta, East Cobb and the surrounding area.

Slabjacking, Concrete Jacking, Mudjacking, Lifting: One Service

If you searched for slab jacking, slabjacking or concrete jacking in Marietta, this is the right page. They are different names for one job: filling the void under a settled slab and raising it back level. Mudjacking pumps a cement-and-soil slurry under the slab. Polyurethane foam injection uses a lighter expanding foam. Concrete lifting and concrete leveling cover both.

Sunken walkways, driveways and patios in Marietta and East Cobb are the usual jobs. When you compare quotes, ask which material goes under the slab. The word on the quote does not tell you.

Why Established Cobb County Driveways Settle

A driveway poured in 1974 in East Cobb typically sits on native Piedmont soil with a thin layer of stone under it — sometimes none at all. That was normal practice and it holds up for a remarkably long time, because undisturbed Piedmont saprolite is reasonably competent ground.

What eventually breaks it is a void. Water finds a route under the edge and washes out fines; a downspout gets re-routed during a renovation; a tree matures and starts moving serious volumes of moisture. Once a void opens, a slab with almost no base beneath it has nothing to span with, and it drops. This is why settlement in these neighbourhoods tends to appear suddenly after decades of nothing — the ground didn't gradually weaken, a cavity opened.

The East Cobb Tree Problem

Mature canopy is what makes these neighbourhoods desirable and it is also what breaks their concrete, in two opposite directions at once. A root running beneath a slab lifts it. The same tree, during an Atlanta summer, pulls enough moisture out of the surrounding clay that the adjacent slab section settles as the soil shrinks.

The practical consequence is that a single East Cobb driveway can show heave and settlement within a few feet of each other. Lifting fixes the settled half. If a root is actively raising the other half, injecting foam under it achieves nothing — we'll identify that at the assessment and tell you what the actual sequence needs to be rather than quoting a lift that won't hold.

When Lifting Is the Wrong Answer

Age itself is not disqualifying — condition is. A 40-year-old driveway that has settled but remains structurally intact is an excellent leveling candidate. One that is map-cracked across its area, spalling at the surface, and shedding aggregate should be replaced; lifting it buys you a level slab that is still at the end of its life. Our concrete repair page covers the middle ground where targeted repair beats both.

Cost in Marietta and Cobb County

Leveling runs $3–$8 per square foot: roughly $300–$600 for a walkway panel, $400–$1,600 for a sunken driveway section, and $1,200–$4,500 for a full two-car driveway. Replacing that same driveway in Cobb County is $4,800–$9,000. Mudjacking sits at the lower end of the range, polyurethane foam at the upper — and foam is generally the better choice on the thin-base slabs common in these neighbourhoods, because it adds almost no weight to ground that has already proven it can't carry what's on it.

Frequently Asked Questions

Is it worth leveling a 40-year-old driveway?

If the concrete is sound and has simply settled, absolutely — it costs a third of replacement. If it's map-cracked and spalling, replace it. Condition decides, not age.

Why do older Marietta driveways settle?

They were poured on native soil with minimal stone base, which was standard at the time. That's fine until a void opens beneath — then there's no base to span it.

How much does concrete leveling cost in Marietta?

$3–$8 per square foot. Two-car driveway $1,200–$4,500 against $4,800–$9,000 to replace.

Do tree roots cause driveway settlement in Cobb County?

Both heave and settlement, often on the same slab — a root lifts one section while the tree dewaters the soil under the next.

Do I need a permit to level concrete in Marietta?

No — it's repair, not new construction. Right-of-way work is the one exception.
