Concrete Repair in Houston for Cracked, Sunken, and Uneven Concrete
A crack in your driveway rarely stays small. The clay soil under Houston keeps moving, water gets in, and the damage spreads.
Slabs on Grade handles concrete repair in Houston for driveways, patios, sidewalks, and commercial flatwork. We find out why the concrete failed and fix that first. Then we tell you straight whether a repair will hold or a section needs to be replaced.

Concrete Repair Contractors for Houston Homes and Businesses
Cracked or sinking concrete can trip a guest, send water toward your house, and cost more to fix every year you wait. Slabs on Grade is a family-owned concrete contractor that has served the Houston area since 2010. Owner Jesus Jimenez grew up working construction with his father and started the company with one truck. Today we repair the concrete you walk and drive on every day, for homeowners, HOAs, property managers, and business owners.
Repair is a core part of our residential concrete services. The work includes crack repair, saw-cut section and panel replacement, trip hazard removal, settled slab repair, and resurfacing. We look at the cause of the damage on every job, not just the crack you can see. Our written workmanship warranty covers defects from our installation, sub-base, or workmanship. It does not cover tree roots, outside soil events, or misuse, and we go over the terms before you sign.
Driveway Repair in Houston
Driveways carry the most weight of any slab on your lot, so they show damage first. We seal cracks, cut out broken or sunken sections, and pour new concrete that ties into the slab you keep. When we re-pour a driveway section, we use the same 4,000 PSI mix and steel rebar we use on our new concrete driveways.
Sidewalk Repair in Houston
Lifted and cracked sidewalk panels are a common trip hazard, and tree roots are a frequent cause. We grind down small lips and replace panels that have heaved or broken. For front walks on a public street, we can pull the permit when the job needs one. Learn more on our concrete sidewalk page.
Patio and Commercial Flatwork Repair
We also repair cracked patios, worn walkways, and commercial flatwork like entrances, loading areas, and parking lots. For businesses, we can often replace only the failed panels so the rest of the lot stays open. See our commercial concrete services for larger jobs.

Family-owned since 2010Signs Your Concrete Needs Repair
Small problems are cheaper to fix than big ones. If you see any of these, have the slab looked at before the next heavy rain or dry spell makes it worse.
Cracks That Keep Growing
Hairline cracks are common and often cosmetic. Cracks that get wider, run across the slab, or have one side higher than the other point to soil movement below.
Heaving or Lifted Panels
A panel that tilts up at a joint was usually pushed by swelling clay or a growing tree root. It will not settle back on its own.
Sinking or Settled Slabs
A driveway apron or patio that has dropped below the garage floor or the next panel often has a void or washed-out base underneath.
Spalling and Flaking
When the top layer chips or peels away, it exposes the stone below. Spalling often starts from a weak surface finish or water sitting on the slab.
Trip Hazards
Even a small lip between panels can catch a toe. On commercial walkways, ADA standards call for changes in level over 1/4 inch to be beveled, and over 1/2 inch to be ramped.
Water Pooling on or Near the Slab
Puddles that sit for hours mean the slab has lost its slope. Water that runs toward your house instead of away from it is a problem to fix soon.
Why Concrete Cracks and Sinks in Houston
- 01
Expansive Clay Soil
Much of the Houston area sits on expansive clay. It swells when it soaks up rain and shrinks when it dries out in summer. That constant movement bends the slab from below until it cracks. Houston rarely has hard freezes, so here the soil, not frost, is the main reason concrete breaks.
- 02
Poor Drainage
Water from downspouts, sprinklers, and heavy storms can soak the soil along one edge of a slab or wash out the base under it. That side swells or sinks while the rest stays put. A repair will not last if water keeps going to the same spot, so we look at drainage on every job.
- 03
Tree Roots
Roots can lift sidewalk and driveway panels as they grow. Large trees also pull a lot of water out of clay soil, which makes the ground shrink and the slab settle near the tree. If roots are the cause, we talk through your options before we pour. We also suggest asking an arborist before any large root is cut.
- 04
A Weak Base From the Start
Many failed slabs were poured too thin, with little or no steel, on soil that was never compacted. Add heavy trucks or trailers and they crack early. When we replace a section, we fix the base first, compact it, and add rebar before the pour.
Types of Concrete Repair We Offer
Concrete Crack Repair
For cracks in a slab that is still level and solid. We clean out the crack and fill it with a product suited to it, like a flexible sealant for cracks that open and close with the seasons. It keeps water and weeds out. The line will still show, so it is a fix, not a makeover.
Section and Panel Replacement
When a panel is broken through, sunken, or lifted, we saw-cut it out at the joints, fix the base, add rebar, and pour a new section. This is the most lasting repair for badly damaged areas, and it costs far less than replacing the whole slab.
Trip Hazard Removal
For a small lip between two sidewalk or patio panels, grinding the high edge down is often enough. It is quick and leaves the rest of the walk in place. If one panel has lifted too far to grind, we replace it instead.
Settled Slab Repair
This concrete slab repair brings a sunken driveway apron, patio, or walkway section back level with the slab around it. We remove the settled piece, fill and compact the void under it, fix any drainage that washed it out, and re-pour it level with the concrete next to it.
Concrete Resurfacing
For a slab that is solid and level but worn, stained, or flaking on top. A new surface layer gives it a clean look. Resurfacing is cosmetic. It will not fix a slab that is still moving, so we only suggest it when the concrete below is sound.
Commercial Concrete Repair
For parking lots, drive lanes, entrances, and walkways at businesses, HOAs, and multi-family sites. We can often replace only the failed panels and build the schedule around your business hours. Areas with heavy truck traffic get a thicker section.
Should You Repair or Replace Your Concrete?
It depends on how much of the slab is damaged and whether the ground under it is still moving. We will tell you when a repair is enough, and when patching would waste your money.
When Concrete Repair Makes Sense
Repair is usually the right call when the damage is in one or two spots and the rest of the slab is level and solid. Think a few narrow cracks, one sunken apron, a lifted sidewalk panel, or a worn top layer. Fixing only what failed can save you a lot compared with a full tear-out.
When Replacement Is the Better Deal
Replacement makes more sense when cracks run through most of the panels, several sections have moved, or old patches keep failing. It also makes sense when the slab needs a new slope to fix drainage, or it is near the end of its life. If a repair would cost close to what new concrete costs, we will say so. Our driveway replacement work uses 4,000 PSI concrete and steel rebar as our standard.
When It Is a Foundation Problem
Cracks in your garage or house slab, doors that stick, and cracks in inside walls are not flatwork problems. Those point to foundation movement. See our concrete foundations page for foundation repair and leveling.

Our Concrete
Repair Process
From First Call to Final Walkthrough
Most repairs follow the same six steps, and we keep you in the loop at each one.
Free On-Site Estimate
We come out, measure the damage, and look for the cause. That means checking drainage, trees, and how the slab was built. We reply to new requests within one business day.
Written Scope and Quote
You get a written estimate that says what we will repair, what we will replace, and why. If the job needs a permit, we tell you up front and handle it.
Cut Out and Remove
For section work, we saw-cut clean edges so the new concrete meets the old in a straight line. We break out the damaged concrete and haul it away.
Fix the Base and Drainage
This is the step that keeps a repair from failing again. We fill voids, compact the base, and set the slope so water drains away from your house.
Reinforce, Pour, and Finish
Steel rebar goes in before the pour. We match the finish of the slab around it as closely as we can, like a broom finish or exposed aggregate.
Cure, Seal, and Walkthrough
We cut control joints, let the concrete cure, and walk the job with you. Plan to keep cars off a new driveway section for about 7 days.
Cracked Driveway Repair Cost in Houston
We price every repair after we see it, because two cracks that look alike can have very different causes. Here is what moves the price.
For a rough idea, Angi's 2026 Houston cost guide puts the average concrete driveway repair at about $1,600, with a typical range of $750 to $2,500. That is a general market figure, not our price. Your written estimate is the number that counts.
Size of the Damage
A few feet of crack costs much less than several panels. Larger areas cost more in total but often less per square foot.
Type of Repair
Sealing cracks or grinding a trip hazard is the low end. Saw-cutting and re-pouring a section costs more but lasts longer.
Fixing the Cause
Regrading for drainage, rebuilding a washed-out base, or dealing with roots adds cost. It is also what keeps the repair from failing.
Removal and Access
Breaking out old concrete and hauling it away is part of most section repairs. Tight backyards can take more labor.
Finish Matching
A plain broom finish is the simplest to match. Stamped or exposed aggregate concrete takes more time to blend in.
Permits
Work in a public right-of-way, like a street-side sidewalk or driveway approach, can need a city permit. We include it in the quote.

Concrete Repair Questions From Houston Property Owners
Straight answers from our crew. Still have a question? Call us and talk to a real person.
Get a Free EstimateCan a cracked driveway be repaired, or does it need to be replaced?
Most cracked driveways can be repaired if the cracks are narrow, the slab is still level, and the damage is limited to one or two sections. Replacement is the better choice when cracks run through most of the panels, sections have sunk or lifted, or the base under the slab has washed out. We look at the whole driveway during a free on-site estimate and tell you which option will last.
How much does concrete repair cost in Houston?
It depends on the size of the damaged area, the type of repair, and whether a drainage or base problem has to be fixed first. Sealing a few cracks costs far less than cutting out and re-pouring a section. Angi's 2026 Houston cost guide puts the average concrete driveway repair at about $1,600, with a typical range of $750 to $2,500. That is a general guide, not our price. We give you a written estimate after we see the job.
Why does concrete crack in Houston?
The main cause is the soil. Much of the Houston area sits on expansive clay that swells when it gets wet and shrinks when it dries out. That movement bends the slab until it cracks. Poor drainage, tree roots, heavy loads, and a thin or poorly compacted base from the original pour make it worse.
How long does a concrete repair last?
A repair lasts as long as the cause stays fixed. A new section poured on a well-compacted base with steel rebar can last as long as new concrete. Filled cracks can open again if the soil keeps moving, so they may need touch-ups over time. That is why we look for the cause, such as drainage or roots, before we quote the repair.
Will the repaired section match my old concrete?
Not exactly at first. New concrete is usually lighter than concrete that has weathered for years, and the color evens out somewhat with time. We match the finish, like a broom finish or exposed aggregate, as closely as we can. If an exact match matters to you, replacing a full panel from joint to joint looks cleaner than a small patch.
Who is responsible for sidewalk repair in Houston?
Under Chapter 40 of the Houston city code, the owner of the property next to a sidewalk is generally responsible for repairing it. Sidewalk work in the City of Houston right-of-way can need a permit through Houston Public Works. We pull permits when a job needs one.
Do you repair house foundations too?
Yes, but that is a different service. This page covers flatwork like driveways, patios, sidewalks, and parking areas. If you see cracks in your home's slab, doors that stick, or cracks in interior walls, see our concrete foundations page for foundation repair and leveling.
