When a garage slab drops, you get a sloping floor, a lip at the threshold, and cracks that spread. We inject high-density polyurethane foam to raise that interior slab back toward its original position — fast, low-mess, and drivable the same day.
A garage slab is poured on its own pad of fill, separate from your home's footings. When that fill moves, the slab follows — and Utah's soils give it plenty of reasons to move.
Builders in newer Utah County and Salt Lake County subdivisions often backfill quickly. When that loose dirt finally compresses under years of weight, the slab above it drops.
A slab plumbing leak, a downspout dumping next to the garage, or eroded sub-base can wash soil out from under the concrete, leaving hollow pockets the slab caves into.
Cars and trucks parked on the same spots every day concentrate weight on already-soft fill, accelerating settling near the door and wheel paths.
Much of the valley sits on expansive clay and soft former Lake Bonneville lakebed sediments that swell when wet and shrink when dry, pulling away from the slab.
Catch it early and the fix stays simple. Watch for these before the gaps and cracks widen.
Water, oil drips, or a dropped ball all roll the same direction — toward the door or back into the garage — instead of staying put.
A visible separation where the garage floor meets the foundation or the back wall means the slab has pulled down and away from the structure.
A step or ridge where the garage door meets the floor or driveway — enough to trip on or scrape a low bumper — points to a settled slab.
Cracks that are widening, offset in height side to side, or sound hollow when you tap them usually mean there's an empty void underneath.
An indoor slab needs a method that's clean, precise, and quick. Foam injection fits a finished garage far better than heavy demolition or a wet slurry.
We drill ports about ⅝ inch across — roughly the width of a dime — then patch them to blend in. No jackhammering, no tearing up your floor.
High-density polyurethane weighs only about 2 lbs per cubic foot. It expands to fill the voids and lift the slab with almost no dust or slurry mess indoors.
The foam cures in about 15 minutes. The slab is walkable in roughly 15 minutes and driveable within about an hour — most jobs wrap in 1–3 hours, same day.
The whole process runs off a hose and small ports, so there's no demolition crew or machinery rolling across your garage floor to do the work.
Lifting your garage slab runs roughly half the cost of tearing it out and pouring a new one — and there's nothing to pay up front.
Most residential jobs run $1,000–$2,500 depending on slab size, the number of injection points, and how far the concrete has dropped. That's roughly half the cost of a full tear-out and replacement. Financing and flexible payment options are available, and there's no deposit — you pay when the work's done. Every job starts with a free inspection and an upfront written price, and it's backed by our 2-year re-lift guarantee. Beehive Concrete Lifting is insured and installs foam only.

We monitor the rise in small increments to raise the slab back toward its original position without forcing it. On rare occasions a slab that's already badly broken may not fully raise, and we'll tell you that up front after the free inspection.
Yes. We plan our injection points around floor drains, cracks, and control joints so the slab rises as one piece without putting stress on those features. Existing cracks often tighten back up as the sections return toward their original height.
Very little. The ports are only about ⅝ inch wide, drilling is quick, and the polyurethane goes in as a liquid that expands in place — there's no wet cement slurry to clean up. We patch the small holes to blend in when we're done.
Yes. The foam cures in about 15 minutes, so the slab is walkable almost right away and driveable within about an hour. Most residential garage jobs finish in 1–3 hours, the same day.
It's backed by our 2-year re-lift guarantee, and Beehive Concrete Lifting is insured. The polyurethane itself is water-resistant and rated for 25+ years, so the lift is built to last.
