Concrete Leveling in Houston

Concrete leveling raises sunken slabs, such as driveways, sidewalks, patios, garage floors and pool decks, back to level without tearing them out. In Houston the usual cause is the soil. Clay under a slab shrinks and swells with the weather, and water can wash soil out from under concrete, leaving voids that let the slab sink.

The two methods you will hear most are mudjacking and polyurethane foam. Mudjacking pumps a cement-based slurry under the slab through small holes to lift it. Foam leveling injects an expanding foam instead. Both fill the void and raise the concrete, and contractors differ on which suits which job, so ask why they recommend theirs. Leveling fixes the slab, but it will not stop whatever washed the soil out, so ask how the contractor will deal with drainage.

Angi reports that mudjacking in Houston typically costs about $4 to $8 per square foot, and small jobs may carry a minimum charge of around $300. Smaller slabs cost more per square foot than larger ones. We did not find a reliable Houston price for foam leveling, so ask contractors for written quotes. These are published ranges, not quotes, and every project is different.

Compare quotes on the same scope: the area being raised, the method, how holes will be patched, the warranty, and what happens if the slab settles again. If the problem is a cracked or sinking house slab rather than a driveway or patio, that is a foundation question, so ask a foundation pro or an engineer to look at it first.

Ask how the contractor protects the surrounding landscape, how soon the concrete can be used after the lift, and whether any cracks will be sealed. Leveling is usually much quicker and less disruptive than replacing a slab, but it only makes sense when the slab itself is in decent shape. If the concrete is badly broken or crumbling, replacement may be the better value, and a good contractor will tell you so.
