Polyurethane Foam Injection Specialists
Precision Foundation Leveling
Lift. Level. Done in a Day.
Not every foundation problem needs piers. For minor settlement, void filling, and surface-level slab corrections, polyjacking delivers a permanent fix in hours ;at a fraction of the cost. We use high-density polyurethane foam to fill voids beneath your concrete and lift it back to level with precision accuracy.

Why Polyjacking
The modern alternative to mudjacking and slab replacement
Polyurethane foam injection has replaced mudjacking as the industry standard for concrete leveling ;and for good reason. It's lighter, faster, more precise, and lasts dramatically longer.
Same-Day Completion
Most residential polyjacking jobs finish in 4–6 hours. Your driveway, patio, or interior slab is usable within 15 minutes of injection.
40–60% Less Than Replacement
Leveling costs a fraction of full slab demolition and repour. Average Austin residential jobs run $2,000–$5,000 depending on area and lift needed.
Penny-Sized Injection Ports
We drill 5/8" holes ;smaller than a dime. No excavation, no heavy equipment tearing up your yard, no multi-day disruption.
Waterproof & Permanent
Closed-cell polyurethane foam won't absorb water, erode, or decompose. It binds to the soil particles beneath, actually strengthening the sub-base.
Applications
What we level across Austin
Polyjacking works on any concrete surface sitting on soil. Here are the most common applications we see in Central Texas homes and businesses.
Interior Slab Floors
Settled living areas, kitchens, or bathrooms where floor tiles have cracked or grout lines have separated. We lift through small ports in the slab ;no furniture demolition required.
Driveways & Garage Floors
The most common polyjacking application in Austin. Garage slabs settle independently from the house foundation, creating trip hazards and water intrusion at the threshold.
Pool Decks & Patios
Settled pool coping and deck sections create drainage problems that funnel water toward the pool or house. Foam leveling restores grade without demolishing your hardscape.
Sidewalks & Walkways
Raised or sunken sidewalk sections are a liability concern and a code issue. Polyjacking restores a smooth walking surface and eliminates trip hazards.
Stoops & Entry Steps
Front stoops pulling away from the house is extremely common in Central Texas. Foam injection lifts the stoop and closes the gap without demolition.
Commercial & Industrial
Warehouse floors, loading docks, and retail pads. Foam leveling minimizes downtime ;most commercial jobs are completed after hours or over a weekend.
Head-to-Head
Polyjacking vs. Mudjacking: A direct comparison
Some Austin contractors still use mudjacking because it's cheaper upfront. Here's why we exclusively use polyurethane foam ;and why it saves you money long-term.
| Feature | Polyjacking | Mudjacking |
|---|---|---|
| Material | High-density polyurethane foam (2–4 lb/ft³) | Cement slurry ("mud") (100+ lb/ft³) |
| Weight added | Virtually none ;won't stress already weak soil | Heavy ;adds significant load to compromised sub-base |
| Hole size | 5/8" diameter (penny-sized) | 1–2" diameter (golf ball–sized) |
| Cure time | 15 minutes ;walk/drive on same day | 24–72 hours before full use |
| Water resistance | Closed-cell, waterproof ;won't erode | Porous ;can wash out in heavy rain |
| Precision | Controlled expansion, accurate to 1/8" | Less predictable, risk of over-lifting |
| Longevity | 10–25+ years (material doesn't decompose) | 3–7 years typical before re-settling |
| Cost (Austin avg.) | $2,000–$5,000 for residential | $1,500–$3,500 (but may need repeating) |
The Process
How precision leveling works
Every leveling job starts and ends with precise elevation data. Here's what happens between.
Precision Survey
We map the entire affected area with a digital level, recording elevations at a grid of points. This produces a "before" elevation profile showing exactly where and how much the slab has settled.
Injection Port Drilling
Small 5/8" holes are drilled through the slab at strategic locations ;typically every 3–4 feet in the settled zone. On interior slabs, we work around existing finishes wherever possible.
Foam Injection & Lift
High-density polyurethane foam is injected beneath the slab. As the two-part compound reacts and expands (within seconds), it fills voids and lifts the concrete. We monitor lift in real time with a laser level.
Final Survey & Seal
Post-lift elevation readings confirm the slab is within tolerance. Injection ports are sealed flush with non-shrink grout. You receive before/after elevation documentation.
Why Austin Homes Settle
The soil cycle that never stops
Austin sits on the Blackland Prairie and Edwards Plateau ;two geological zones with dramatically different soil behavior. East Austin's black clay (Plasticity Index 35–55+) swells when wet and shrinks when dry, creating voids beneath concrete that cause settlement. West Austin's limestone substrate creates thin soil cover that erodes quickly during heavy rain.
Both conditions produce the same result: gaps beneath your concrete that cause it to crack and settle. The difference matters for choosing the right repair. Polyjacking fills these voids permanently while adding virtually no weight to the already compromised sub-base ;unlike mudjacking, which adds 100+ pounds per cubic foot of heavy cement slurry.

Honest Assessment
When polyjacking isn't the right answer
We'd rather tell you the truth than sell you the wrong solution. Here are situations where foam leveling isn't appropriate ;and what we recommend instead.
Severe structural settlement (>2" differential)
Steel or helical piers are needed to reach load-bearing strata. Polyjacking can't address the root cause when deep soil is the problem.
Learn about steel piersActive heave from plumbing leak
The moisture source must be eliminated first. Lifting a heaving slab locks it in a distorted position. We diagnose before prescribing.
Learn about slab diagnosisBadly cracked or deteriorated concrete
If the slab itself is broken into multiple pieces or structurally compromised, leveling a damaged slab won't restore integrity. Partial or full replacement may be needed.

Common leveling questions
Have a question we haven't covered? Call us at 737-302-6202 ;we're happy to talk through your situation.
- How much does polyjacking cost in Austin?
- Most residential polyjacking jobs in the Austin area run $2,000–$5,000. The cost depends on the square footage being lifted, the depth of voids, and how much lift is needed. A 10'×20' garage slab that's settled 1" might cost $1,800–$2,500. We provide free on-site quotes with exact pricing.
- How long does foam leveling last?
- Polyurethane foam doesn't decompose, absorb water, or break down over time. The material itself is essentially permanent. However, if the underlying soil conditions that caused the original settlement aren't addressed (like poor drainage), the soil around the foam can continue to shift. We assess drainage as part of every leveling job.
- Is polyjacking safe for interior floors with tile or hardwood?
- Yes, with caveats. The lift is gentle and controlled, so tile and hardwood generally survive well. However, if tile is already cracked from the settlement, lifting the slab won't un-crack the tile ;it just prevents further damage. We discuss finish expectations before starting.
- Can you level a foundation with foam instead of piers?
- For minor settlement (under 1–1.5"), polyjacking can be an effective and less expensive alternative to piers. For moderate to severe settlement, or when the cause is deep soil movement, piers are the correct solution. We never recommend foam when piers are warranted ;and vice versa.
- What's the difference between polyjacking and mudjacking?
- Mudjacking pumps heavy cement slurry under the slab, which adds weight to already compromised soil. Polyjacking uses lightweight polyurethane foam that's waterproof, cures in minutes, and won't re-settle. Mudjacking is cheaper upfront but often needs to be repeated within 3–7 years. We exclusively use polyurethane foam.
- Will foam leveling fix my drainage problem?
- Leveling can restore proper surface grade so water flows away from your foundation instead of pooling against it. However, if you have subsurface drainage issues (high water table, French drain failure), those need to be addressed separately. We often coordinate leveling with drainage corrections for a complete solution.
A settled slab only gets worse.
Every rain cycle widens the voids. Every drought deepens the cracks. A leveling job that costs $2,500 today could become a $10,000 pier installation if the settlement progresses. Get a free assessment and know where you stand.
