If any of these sound like your slab, you probably need it lifted before it gets worse.
Your basement floor or sunroom slab has dropped, and there's a gap where the slab meets the foundation wall. Water sneaks in every time it rains.
A door that worked fine last year now scrapes the floor or won't close all the way. The slab moved, the frame shifted, and the door followed.
One section of concrete sits a quarter-inch or more below the next. People stub toes on it. Anything over that height is a real trip hazard.
You tap the slab and it sounds like a drum. That hollow sound means the dirt under it is gone and the slab is sitting on a void.
Concrete slab lifting raises a sunken slab back to its original height. Your slab is fine. The dirt under it isn't. We drill small holes, pump material underneath, and the slab rises back into place. You walk on it the same day.
We handle every type of sunken slab — basement floors that pulled away from the wall, sunroom slabs that dropped from the house, garage floors that dipped in the corner, interior slabs in slab-on-grade homes, and porches that scrape the door now.
Two-part foam injected through dime-sized holes. It expands in seconds, fills the void, and lifts the slab. Cures in about 15 minutes. Lightweight, waterproof, and lasts the longest of any method.
A cement and soil slurry pumped under the slab through larger holes. Lower price, works well on big outdoor slabs, but heavier and shorter-lived than foam. We use it when it's the right call — not as our default.
Sometimes the slab hasn't dropped much yet, but there's already a void underneath. We fill it before the slab fails. Same process, no full lift needed.
Our Process
We come out, walk the slab with a level, find the dip, and check what caused it. You get a written price before we drill anything.
Holes are dime-sized for foam, slightly larger for mud. They go in a planned pattern so the slab lifts evenly — not in one spot.
We pump material underneath in small amounts. The slab rises while we watch the level. We stop the second it's where it needs to be.
Holes get patched with cement mortar. We sweep up. With foam, you walk and drive on it the same day.
We don't push replacement when lifting works. Replacement costs two to three times more and takes days. Lifting fixes the same problem in hours. If your slab can be lifted, we'll lift it. If it can't, we'll tell you that too.
The price you see is the price you pay. We give you a written quote before we start. No change orders, no upsells once we're on site, no surprise charges at the end. The number we wrote down is the number you sign for.
Most jobs are done the same day. We don't book you out three weeks. We don't disappear after the quote. Foam cures in 15 minutes, so by the time we leave, your slab is ready to use.
Foam lifts hold 5 to 20 years or longer in most cases. Mudjacking holds 2 to 5 years before the slurry can wash out. The biggest factor is what caused the slab to sink — if water keeps running under it, even the best lift won't last. Fix the water source and the lift holds.
Polyjacking uses lightweight polyurethane foam through small holes. It cures in 15 minutes and lasts longer. Mudjacking uses a heavier cement slurry through bigger holes and takes a day or two to cure. Foam costs more up front. Mud is cheaper but doesn't last as long. We explain both before you pick.
Yes — usually 50 to 70 percent less. Replacement means demo, haul-off, new pour, and waiting for it to cure. Lifting keeps the slab you have and just fixes what's underneath. Same outcome, lower cost, and you don't lose use of the area for days.
We lift in small amounts and watch the level the whole time. The second the slab is back where it should be, we stop. Slabs that crack during lifting are usually slabs that were already cracked before — and those we tell you up front to replace, not lift.
Sometimes. Hairline cracks lift fine. A slab broken into several pieces lifts unevenly because each piece moves on its own. If lifting won't give you a clean result, we'll tell you. Concrete crack repair covers the cracks that don't need a lift. Replacement is the right call in worse cases — and we'll say so instead of taking your money.
