Mudjacking Services Austin TX — Lift Sunken Concrete Without Full Replacement
Got a sunken driveway, sidewalk, or patio slab that looks like it is slowly disappearing into the ground? Think you have to replace the whole thing? We offer mudjacking services in Austin that lift sunken concrete back into place for far less than a full tear-out.
Mudjacking is one of the most cost-effective fixes for sunken concrete slabs. We drill small holes in the slab, pump a cement slurry mixture underneath, and lift the concrete back to its original position. The process is faster than replacement, costs less, and leaves you with a stable surface that is ready to use within 24 hours. Austin’s expansive clay soil is one of the biggest reasons slabs sink here. We know how to account for that when we work so the fix actually holds. If you have a sunken slab on your property, call us at (512) 337-4425 and let’s find out if mudjacking is the right solution for you.

What Is Mudjacking and How Does It Work?
Mudjacking lifts sunken concrete by pumping a cement-soil mix into the empty space underneath it through small drilled holes. The mix fills the gap and pushes the slab back up — no tearing out, no full replacement.
- We drill 1.5–2 inch holes through your slab.
- We pump a cement, soil, and water mix under pressure through the holes.
- The mix fills the empty space and starts lifting the slab — we watch the level the whole time.
- When it reaches the right height, we stop pumping.
- We patch every hole with color-matched concrete. You can walk on it in a few hours. You can drive on it in 24–72 hours.
What Mudjacking Is and How It Lifts Sunken Concrete in Austin
Here’s something a lot of Austin homeowners don’t realize: your slab didn’t sink because it was built wrong. It sank because the dirt underneath it moved.
Austin sits on some of the most reactive clay soil in Texas. That clay swells when it gets wet and shrinks hard when it dries out.
According to the Texas A&M AgriLife Extension Service for Travis County, Austin’s Blackland Prairie clay soils shrink and swell with every moisture change — cracking the ground and heaving objects like patios right along with it.
We’ve seen Austin patios develop voids of 2–4 inches underneath them after a bad drought year. The 2022 drought hit this area hard. A lot of the jobs we look at today have voids that opened up that summer and never closed back.
Why mudjacking works so well here:
- The cement-soil mix we pump is heavy and dense
- It fills big clay-shrinkage voids better than lightweight foam
- It’s built for large outdoor slabs — driveways, patios, the stuff Austin homes are full of
One thing to know: Mudjacking is for slabs that are still in one piece. If your concrete is broken up or crumbling, that’s a different conversation. We’ll tell you straight when we come out. |
Which Sunken Concrete Surfaces Can Be Mudjacked in Austin
We get this question a lot: “Can you do my driveway? My patio? My pool deck?”
Here’s a simple breakdown:
Surfaces We Can Mudjack
| Surface | Why It Works |
| Driveways | Built for vehicle weight — our mix handles the load |
| Patios | Lifts settled slabs causing drainage issues or trip hazards |
| Sidewalks | Raises sunken panels back to grade, removes trip hazards |
| Pool decks | Works on sections away from the pool shell |
| Garage aprons | Fixes that annoying bump between your driveway and garage floor |
| Commercial flatwork | Warehouse floors, dock aprons, parking lots, equipment pads |
Surfaces Where Mudjacking May Not Be Right
| Surface | Why We’d Recommend Something Else |
| Slabs under 3 inches thick | Pump pressure can crack an already thin slab |
| Broken or fragmented slabs | Can’t lift pieces as a unit |
| Pool deck edges at the pool shell | Foam is safer near waterproofed surfaces |
| Indoor or enclosed slabs | Foam is cleaner — no slurry mess inside |
| Local note: Round Rock and Cedar Park homeowners with big two-car or three-car driveways call us constantly. Those wide slabs — 600 to 1,200 square feet — are exactly where mudjacking saves the most money over foam. The bigger the slab, the bigger the gap in price. |
We also see a lot of garage apron problems in Austin homes built between 2000 and 2012. Builders poured the garage approach slab separately from the driveway. When the clay dried out, that slab settled on its own. If you’ve got a bump or a drop where your driveway meets your garage, that’s probably what happened.
Mudjacking vs. Polyurethane Foam vs. Full Replacement for Austin Concrete
We hear this all the time: “I got three quotes — one for mudjacking, one for foam, one to rip it all out. Who do I believe?”
Honest answer: all three can be right depending on the situation. Here’s how to think about it.
Quick Comparison Table
| Mudjacking | Polyurethane Foam | Full Replacement | |
| Cost | Lowest | Middle | Highest |
| Cure time | 24–72 hrs for vehicles | 15–30 minutes | 7 days |
| Best for | Large outdoor slabs | Near plumbing, indoors, high water table | Broken or failed slabs |
| Weight | Heavy, dense fill | Lightweight | N/A — new pour |
| Longevity | 5–15 years with drainage fix | Similar | 25–30 years |
Choose Mudjacking When:
- Your slab is large and outdoors — driveways, patios, sidewalks
- You want the lowest cost per square foot
- You can wait 24–72 hours before driving on it
- Your drainage is decent and the base stays mostly dry
Choose Foam When:
- You need it usable same-day
- The slab is near buried pipes or utilities
- You have ongoing water or drainage problems
- It’s an indoor or enclosed space
Replace It When:
- The slab is in pieces — can’t lift what’s already broken
- It’s been mudjacked before and sank again within 5 years
- Rebar is showing and rusted
- The surface is more than 30 years old with widespread damage
| What we see in Pflugerville and Kyle: Those lots have some of the heaviest clay in the Austin metro. The drainage varies a lot from lot to lot too. Honestly, those are the hardest calls we make. We always recommend an on-site look after a rain event — that tells us more than anything else. The 2022–2023 drought left a lot of those slabs with deep, wide voids that were perfect for mudjacking. |
How Mudjacking Works on an Austin Job — Step by Step
We know you want to know what the day actually looks like. Here’s what happens from the time you call us to the time we pull out of your driveway.
Before We Arrive — What You Need to Do
- Move your cars off the driveway or slab at least 24 hours before we get there
- Clear off any furniture, pots, or equipment sitting on the slab
- Make sure we can get to a water source on your property — we need it to mix the slurry
- Flag any sprinkler heads, cleanouts, or buried lines near the slab edge — we won’t drill near those
| Pro tip from experience: The more clearly you mark your irrigation heads, the faster we move. We’ve accidentally clipped lines on unmarked systems before — it adds time and nobody’s happy. A few minutes with some flags saves a lot of hassle. |
The Day of the Job — Step by Step
| Step | What’s Happening |
| 1. Level check | We use a laser or 4-foot level to find the low spots and mark drill locations |
| 2. Drilling | We drill 1.5–2 inch holes every 4–6 sq ft of settled area — takes 1–3 min per hole |
| 3. Pump hookup | We connect the slurry pump and start at the first hole |
| 4. Filling | We fill holes in order — nearby holes let air out so slurry spreads evenly |
| 5. Monitoring | We watch the level throughout — we stop the moment it hits the right grade |
| 6. Patching | Every hole gets patched with color-matched concrete filler. Surface gets cleaned. |
How Long Will We Be There?
| Job Size | Time on Site |
| Small slab (100–300 sq ft) | 1.5–3 hours |
| Large driveway or patio (400–800 sq ft) | 3–5 hours |
| Commercial or multi-slab job | Half day to full day |
| South Austin and Manor homeowners: We know your lots. Side-yard gates, big oak trees growing right up to the slab, narrow access points — we deal with that all the time in South Austin. We carry hand-pump equipment for exactly those spots where a full pump truck can’t fit. And if you’re out in Manor on a rural lot, we’ll ask about your septic system before we drill anything. Lateral lines under slabs are more common out there than people think. |
How Long Mudjacking Lasts in Austin and When You Can Drive on It Again
Let’s be straight with you — because we’ve heard the horror stories too.
Mudjacking is a durable repair. It is not a forever fix. Anyone who tells you it’s permanent doesn’t understand Austin’s soil. The clay under your slab will move again. The question is how well you manage it going forward.
When Can You Use It Again?
| Use | Wait Time |
| Walking on it | A few hours |
| Patio furniture, grills | 24 hours |
| Passenger cars | 24 hours minimum; 48 hours in summer |
| Heavy trucks and trailers | 72 hours |
| Why summer takes longer: Austin summers dry the soil out fast. When soil is very dry, the slurry takes a little more time to fully spread and set. We always give summer jobs an extra day before heavy loads go back on. |
How Long Will It Last?
| Scenario | Expected Lifespan |
| Mudjacking only, no drainage fix | 3–7 years |
| Mudjacking + drainage corrections | 10–15+ years |
| High water table or flood-prone site | Consider foam instead |
What Makes It Last Longer:
- Fix the drainage while we’re there — redirect your downspouts, extend your HVAC condensate line, regrade soil away from the slab edge. This is the single biggest thing you can do.
- Deal with tree roots — if a root is under your slab, it will keep making voids. Address it now.
- Seal the surface — closes off existing cracks so water can’t get under the new slurry base.
What Shortens It:
- Leaving drainage problems in place after the lift
- Tree roots that keep growing under the slab
- Properties with chronic flooding or high water tables
| Georgetown and Leander homeowners near the lakes: Properties close to Lake Georgetown and Lake Travis tributaries have a different problem than most of Austin. The water table rises and falls with the seasons out there. That kind of movement is hard on mudjacking long-term. For those properties, we often recommend polyurethane foam instead — it holds up better when the ground underneath stays wet for long stretches. |
What Mudjacking Saves Austin Homeowners Compared to Concrete Replacement
We’ll give you the honest version of this — not the sales pitch version.
The Cost Reality
| Factor | Mudjacking | Full Replacement |
| Demo and haul-off | Not needed | Required |
| New sub-base prep | Not needed | Required |
| New concrete pour | Not needed | Required |
| Cure time before use | 24–72 hours | 7 days |
| Typical cost vs. replacement | 25–50% less | Full price |
On a 500 square foot driveway, you’re skipping the demo, the haul-off, the sub-base work, and the cure wait. That’s real money and real time saved.
Does Mudjacking Add Home Value?
Here’s the straight answer: no, not directly. A mudjacked driveway isn’t worth more than a level one. But a sunken driveway absolutely costs you money when you sell.
Here’s what we’ve seen happen on Austin listings:
- Buyers flag sunken concrete in inspection reports
- Their agent uses it to push for a price reduction
- A $1,500–$3,000 mudjacking job becomes a $5,000–$8,000 negotiation point
- Sellers lose more than they would have spent on the fix
Getting it done before you list — and keeping the invoice and photos — removes that leverage entirely.
For Austin Rental Property Owners
Mudjacking is one of the best maintenance investments per dollar for rental portfolios. Here’s why:
- Fast turnaround — most jobs done same day, zero tenant displacement
- Liability reduction — a trip hazard sidewalk is a lawsuit waiting to happen
- Compliance — Travis County and surrounding municipalities send notices for uneven sidewalk panels. Mudjacking resolves most of them in a single day at a fraction of replacement cost.
- Documentation — a dated invoice and before/after photos check the box for most property management and insurance requirements.
| Real talk on Austin’s resale market: Even in a hot seller’s market, sunken concrete gets flagged. We’ve talked to homeowners who lost $6,000–$10,000 in negotiations over a driveway that would have cost $2,000 to fix. Get it done before the listing goes live. It always costs less than what a buyer will ask for. |
Frequently Asked Questions About Mudjacking Services in Austin
Accordion Content
Mudjacking pumps a cement-soil mix through small drilled holes in your sunken slab, fills the void beneath it, and lifts the slab back to level — then patches the holes with color-matched concrete. You can walk on it in a few hours and drive on it in 24–72 hours. It works especially well on Austin slabs with clay-shrinkage voids from drought years like 2022.
Both lift sunken slabs — they just use different materials. Mudjacking uses a cement-soil mix. It’s heavier, costs less per square foot, and is best for large outdoor slabs that carry vehicle weight. Foam uses expanding resin. It cures in 15–30 minutes, weighs less, and holds up better near plumbing and in high-water-table areas. The bigger your slab, the more you save going with mudjacking.
Yes — typically 25–50% less than full replacement. But there are times to replace: when the slab is in pieces, when rebar is exposed and rusted, when it’s been mudjacked before and sank again within 5 years, or when the surface has widespread damage beyond just the settling. We’ll tell you which category you’re in when we come out.
With drainage corrections in place, most jobs last 10–15 years or more. Without fixing the drainage, expect 3–7 years before the clay starts moving again. Vehicles can go back on it after 24 hours minimum — 48 hours in summer, 72 for heavy trucks.
Driveways, patios, sidewalks, pool decks away from the shell, garage aprons, and commercial flatwork. Not the right fit for slabs under 3 inches thick, broken slabs, pool deck sections right at the pool shell, or indoor surfaces — foam is better in those cases.
It doesn’t add new value — it protects the value you already have. A sunken driveway or patio is a buyer negotiation point. Fixing it before you list removes that leverage. For rental owners, it clears Travis County sidewalk compliance notices fast and at a fraction of replacement cost. And across the board, it runs 25–50% less than tearing it out and starting over.
