Is foam concrete lifting worth it, or should I just replace the slab?

If the slab is mostly in one piece and has only sunk, foam lifting usually costs $800 – $3,500 in Greater Columbus versus $6,000+ for tear-out and replacement, and it is done the same day. If the slab is crumbling, broken into many pieces, or pushed up by tree roots, replacement is the better fix.

What is the difference between mudjacking and foam lifting?

Mudjacking pumps a heavy cement-and-soil slurry through holes roughly 1.5 to 2 inches wide. Foam lifting injects a lightweight polyurethane foam through dime-sized holes (about 5/8 inch). The foam weighs far less, so it adds little load to the soft clay soils under Central Ohio slabs, and it cures in about 15 minutes.

Can foam be used on concrete that was mudjacked before?

Sometimes. Old mudjacking slurry under a slab can block or redirect the foam. We check the old injection holes and how the slab has moved before quoting, and tell you if lifting is not a good bet.

Will lifted concrete sink again?

Foam fills the empty space under the slab and does not wash out the way loose soil does, but water still matters. If a downspout or poor grading keeps soaking the soil next to the slab, fix that drainage too.

Can foam lower concrete that has been pushed up?

No. Lifting only raises sunken concrete. Slabs pushed up by tree roots or frost need grinding, root work or replacement.

Cost and Downtime at a Glance

Foam lifting, mudjacking and replacement compared
Method	Typical cost (Greater Columbus)	Hole size	Back in use
Polyurethane foam lifting	$800 – $3,500	About 5/8 inch (dime-sized)	About 15 minutes
Mudjacking (cement slurry)	Often quoted lower than foam	Roughly 1.5–2 inches	Typically a day or more
Tear-out & repour	$6,000+	Full removal	3–7 days plus curing time

Foam and replacement ranges are our Greater Columbus pricing. Mudjacking prices vary by contractor; we don't offer it.

Lifting is usually the right call when…

The slab is in one or two pieces and has simply dropped
Cracks are hairline or narrow, not crumbling
You want it usable the same day
You need to fix a trip hazard without tearing out the surface

Replacement is the better fix when…

The concrete is crumbling, flaking or broken into many pieces
The slab has been pushed up by tree roots or frost (foam can't lower it)
You want a new size, shape or finish anyway
Old mudjacking has failed in a way foam can't get past

Foam vs Mudjacking: What Columbus Homeowners Ask

Why does foam cost more than mudjacking?

Foam material costs more, but it is light, goes in through small holes and is ready in about 15 minutes. Mudjacking slurry is heavy, and on the soft Crosby-Miami-Kokomo Silty Clay Loam under Central Ohio slabs, extra weight is exactly what you want to avoid.

My mudjacking sank again within a few years. Why?

Slurry can wash out or compress, and it adds weight to soil that is already moving through Central Ohio's freeze-thaw and wet-dry cycles. Foam does not wash out, but drainage still matters: send downspouts away from the slab so the soil next to it isn't soaked every rain.

For $2,000 should I just pour a new stoop?

Sometimes, yes. Get both prices. A small, badly cracked stoop can be worth repouring. A sound slab that only dropped is usually cheaper and faster to lift — and you keep the concrete you already have.
