Concrete Raising in Houston, TX
Your Concrete Isn't Broken, It's Just Sitting Too Low
Walk around enough Houston neighborhoods and you'll spot the same thing everywhere. A sidewalk panel that dropped an inch below its neighbor. A driveway that tilts toward the garage. A patio slab that slopes the wrong way, so rain runs toward the house instead of away from it. The concrete itself is often still in good shape. It just isn't sitting where it used to.
That's good news, because it means you may not need to rip anything out. Concrete raising lifts a sunken slab back to level by filling the empty space underneath it, which is usually faster, cleaner, and cheaper than demolition and a new pour. PaveTec raises concrete across Houston, and we'll tell you honestly whether your slab is a good candidate or whether replacement makes more sense.
Why Concrete Sinks in Houston
The ground is the culprit. Houston sits on expansive clay that swells when it's soaked and shrinks as it dries, and over many wet and dry cycles that movement can leave gaps under a slab. Heavy rain makes it worse. A hard storm can wash soil out from under an edge or carry it away through a crack, and a leaking downspout or an irrigation line that soaks the same spot for months can do the same slowly.
Once a void opens up, the slab above it has nothing to hold it up. It settles under its own weight and the weight of whatever drives or walks across it. If the cause isn't fixed along with the slab, it can sink again, which is why we look at water first.
How We Raise Concrete
Mudjacking. A mix of soil or sand, water, and cement is pumped through small holes drilled in the slab. As it fills the void, mudjacking pushes the concrete back up to level. It's a long-established method and works well on heavier slabs like driveways and large patios.
Polyurethane foam leveling. Instead of a cement slurry, an expanding polyurethane foam is injected through smaller holes. It fills voids and lifts the slab as it expands. It's lighter than a slurry, which matters on soft or already weak soil, and the holes are usually smaller.
We'll talk through which approach fits your slab, the soil underneath, and your budget, rather than defaulting to one method for every job.
What Can Be Raised
Most flat concrete that has settled can be considered, including driveways, walkways and sidewalks, patios and pool decks, garage floors, steps and stoops, and slabs that have pulled away from the house. Whether it's a good candidate depends on the condition of the concrete itself, which is why every job starts with a close look.
When Raising Isn't the Right Answer
We'd rather tell you the truth than lift something that won't last. If the slab is badly cracked into many pieces, crumbling, or was poorly built to begin with, lifting it may only buy you a short time and replacement is the better value. The same goes for a slab that keeps sinking because the underlying problem is still there. We'll point out which situation you're in and show you why, so you can compare the options yourself.
Signs Your Concrete Needs Lifting
Look for slabs that sit higher or lower than the ones next to them, uneven edges that catch a foot or a wheel, concrete that slopes toward your home, water pooling on a surface that used to drain, and gaps opening between the slab and the house or between panels. A sunken panel is also a trip hazard, which is reason enough to deal with it sooner rather than later.
How the Process Works
Inspection. We look at the damaged slab and the area around it, checking for the source of the soil loss, including drainage, downspouts, and leaks.
Straight recommendation. We explain whether raising makes sense, which method we'd use, and what it will cost.
Drilling. We drill small injection holes in the slab, placed to lift it evenly.
Lifting. We pump in the fill material and raise the slab gradually, checking level as we go.
Patching and cleanup. We seal the holes, clean the area, and walk the finished work with you.
Concrete Raising Across Houston
PaveTec raises sunken concrete throughout Houston and nearby areas, including the Heights, Katy, Sugar Land, Pearland, and The Woodlands. Older homes with settled walkways and newer subdivisions where fill soil is still compacting each have their own sinking problems, and we've worked on both.
Keeping It Level
Once your concrete is raised, a few habits help it stay put. Make sure gutters and downspouts carry water well away from slabs. Fix leaking irrigation or plumbing near concrete promptly. Keep soil from washing out along edges. And if you see a slab starting to dip again, call early, because small movement is much easier to correct.
Wondering If Your Slab Can Be Saved?
Send PaveTec a few photos or set up a visit, and we'll tell you whether your concrete can be lifted or if it's time to replace it. You'll know where you stand before you commit to anything.
Frequently Asked Questions
How much does concrete raising cost in Houston? It depends on the size of the slab, how far it has sunk, and the method used. Raising is usually less expensive than replacing the concrete, and we'll give you an exact price after an inspection.
Is raising concrete better than replacing it? Often it's faster and less disruptive, and it costs less, when the concrete itself is still in good shape. If the slab is badly cracked or crumbling, replacement can be the better value, and we'll tell you honestly which applies.
How long does it take? Many raising jobs can be done in a few hours to a day, depending on how much concrete is involved.
How soon can I use the concrete again? Often within a short time after the work is done, but it depends on the material used. We'll give you a specific timeline for your job.
Will the concrete sink again? It can if the cause of the soil loss isn't addressed. That's why we check for drainage problems, leaks, and washout, and recommend fixing them alongside the lift.
Does lifting fix the cracks? Not by itself. Raising levels the slab, and we can repair cracks and seal the surface as part of the same job.
