Sunken driveways, sidewalks, patios, garage floors, and pool decks do not need to be torn out. Modern concrete leveling raises sunken slabs back to grade in hours — at a fraction of the cost of replacement.
We drill a few small holes through the sunken slab, then inject high-density polyurethane foam underneath. The foam expands, fills voids, and gradually lifts the slab back to level. Once the slab is at proper elevation, the holes are patched. The whole process typically takes 1–3 hours per area.
Older "mudjacking" used a slurry of soil, sand, and cement to lift slabs. It works, but it is messy, requires bigger holes, adds significant weight (which can cause re-sinking), and takes 24+ hours to cure. Polyurethane foam is lighter, cures in minutes, requires only small dime-sized injection holes, and is waterproof. We use polyurethane.
Same reason foundations move: soil. When soil under a slab compacts, washes out, or shrinks, the slab loses support and sinks. Common causes include poor original compaction, plumbing leaks, downspout discharge, tree roots, or just decades of normal soil settlement.
Replacement requires demolition, removal, new pour, days of curing, and is typically 3–5x more expensive. Leveling fixes the same problem in a few hours, with no demo and no waiting.
A typical residential concrete leveling job runs $400–$1,500 per area depending on size and lift height. Larger commercial projects scale from there. Most jobs are completed in a single visit. The leveled slab can be walked on immediately and driven on within a few hours.
If your slab is severely cracked, crumbling, or has lost structural integrity, replacement may be the better call. We tell you honestly during the inspection. Leveling is for slabs that are intact but have settled.
Most residential concrete leveling jobs in Houston run about $400 to $1,500 per area, depending on the size of the slab and how much lift it needs. That is typically 3 to 5 times cheaper than tearing out and replacing the concrete. We give you a firm price after a free on-site look.
Most jobs are done in a single visit, usually 1 to 3 hours per area. Because we use polyurethane foam, the slab can be walked on right away and driven on within a few hours.
Polyurethane foam is waterproof and does not wash out or break down, so the lift is long-lasting. As long as the underlying cause (such as a plumbing leak or poor drainage) is addressed, a leveled slab stays put, and we back our work with a warranty.
We use polyurethane foam. It is lighter, so it will not re-sink the slab, cures in minutes instead of a day, needs only small dime-sized holes, and is waterproof. Traditional mudjacking is messier, heavier, and slower.
Yes. Foam injection lifts a sunken pool deck back to grade without disturbing the pool or requiring demolition. It is one of the most common concrete leveling jobs we do in Houston.
If the slab is intact but has settled, leveling is faster and far cheaper. If it is severely cracked or crumbling, replacement may be the better call, and we will tell you honestly during the free inspection.
Concrete leveling with polyurethane foam is quick but precise. First, we mark the low areas and drill a series of dime-sized holes, about 5/8 inch, through the sunken slab. Next, we inject high-density polyurethane foam through those holes; the foam expands in seconds, fills the voids under the slab, and raises it back to grade in a controlled lift while we monitor elevation. Once the slab is level, we patch the holes, and the surface is ready to use within a few hours.
Three things drive the price: the size of the slab, how much lift it needs, and how many voids have to be filled. A single sunken driveway panel or a short section of sidewalk is inexpensive; a large patio, garage floor, or pool deck with significant settlement costs more because it takes more foam. Because leveling avoids demolition, new concrete, and days of curing, it typically runs a fraction of full replacement — and we give you a firm number after seeing the slab.
Polyurethane foam is waterproof and does not wash out, compress, or break down the way older mudjacking slurry can, so a properly leveled slab stays put as long as the underlying cause — a plumbing leak, poor drainage, or eroding soil — is addressed. That is why we look at drainage during the visit and, when needed, pair leveling with a drainage fix so the concrete does not sink again.
