Concrete Raising in Austin, TX

Is Your Driveway Tilting, or Is It Just You?

It usually starts small. You notice the walkway panel by the front door sits a little lower than the one next to it. Then the patio seems to slope toward the house instead of away from it. A few months later you catch your toe on a lip that wasn't there before. In Austin, that's often a slab that's settled, not a slab that's ruined.

Concrete raising lifts a sunken slab back to level by filling the empty space beneath it, so you may be able to skip the demolition and the new pour. PaveTec raises concrete across the Austin area, and we'll tell you honestly whether your slab is a good candidate or whether replacing it makes more sense.

Why Concrete Settles Around Austin

Austin's ground is a patchwork. In some neighborhoods, limestone sits close to the surface, and a short distance away you hit expansive clay that swells after rain and shrinks during dry spells. Soil like that doesn't stay put under a slab for long.

The weather adds to it. Long dry stretches followed by hard, fast storms can wash soil out from under edges and through cracks, especially on sloped lots where runoff moves quickly. Mature tree roots pull moisture from the soil and shift things around underneath. A downspout that dumps beside a patio, or an irrigation leak that keeps one area wet, can quietly carve out a void over time. Once there's a gap under the concrete, the slab settles into it.

If the cause isn't dealt with, the slab can sink again, which is why we start by looking at where the water and soil are going.

How We Raise Concrete

Mudjacking. A mixture 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 proven method for heavier slabs like driveways and large patios.

Polyurethane foam leveling. An expanding polyurethane foam is injected through smaller holes, filling voids and lifting the slab as it expands. It's lighter than a cement slurry, which can matter on soft or weak soil, and the injection holes are typically smaller.

We'll talk through which approach suits your slab, the soil beneath it, and your budget instead of using the same method on every job.

What We Can Raise

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 yours is a good candidate depends on the condition of the concrete, which is why we inspect before we recommend anything.

When Raising Isn't the Right Call

We'd rather be straight with you than lift something that won't last. If the slab is cracked into many pieces, crumbling, or was poorly built from the start, lifting may only buy you a little time, and replacement is the better value. The same applies if the underlying cause of the soil loss is still active. We'll explain which situation you're in so you can weigh the options yourself.

Signs Your Concrete Needs Lifting

Watch for slabs sitting higher or lower than the ones beside them, lips and uneven edges that catch a foot or a wheel, concrete sloping toward your home, water pooling where it used to drain, and gaps opening between the slab and the house or between panels. A sunken panel is also a trip hazard, so it's worth dealing with sooner rather than later.

How It Works

1. Inspection. We examine the slab and the surrounding ground, looking for the source of the soil loss, including drainage, downspouts, roots, and leaks.

2. Straight recommendation. We explain whether raising makes sense, which method we'd use, and what it will cost.

3. Drilling. We drill small injection holes, placed to lift the slab evenly.

4. Lifting. We pump in the fill material and raise the slab gradually, checking level as we go.

5. Patching and cleanup. We seal the holes, clean up, and walk the finished work with you.

Concrete Raising Across the Austin Area

PaveTec raises sunken concrete throughout Austin and the surrounding communities, including Round Rock, Cedar Park, Pflugerville, Georgetown, and Lakeway. Hill country lots where runoff carries soil away, older neighborhoods with large trees, and newer subdivisions where fill is still settling all have their own reasons for sinking slabs, and we've worked on each.

Keeping It Level

A few habits help raised concrete stay where it belongs. Send gutters and downspouts well away from slabs. Fix irrigation or plumbing leaks near concrete quickly. Keep soil from eroding along edges. And if you see a slab starting to dip again, call early, since small movement is much easier to correct than a big drop.

Curious Whether Your Concrete Can Be Raised?

Send PaveTec a few photos or set up a visit, and we'll tell you if your slab can be lifted or if replacement makes more sense. You'll know your options before you commit.

Frequently Asked Questions

How much does concrete raising cost in Austin? It depends on the size of the slab, how far it has sunk, and the method used. Raising usually costs less than replacing the concrete, and we give you an exact price after an inspection.

Is raising concrete better than replacing it? Often it's faster, less disruptive, and less expensive when the concrete itself is still in good shape. If the slab is badly cracked or crumbling, replacement may 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 soon after the work is finished, but it depends on the material used. We'll give you a specific timeline for your job.

Can tree roots cause a slab to sink? They can contribute, by changing soil moisture and shifting the ground beneath a slab. We look at roots as part of the inspection and talk through your options.

Does lifting fix the cracks? Not on its own. Raising levels the slab, and we can repair cracks and seal the surface as part of the same job.
