Polyjacking in Eagle Mountain, Utah
Polyurethane foam lifting raises sunken concrete in hours, cures in minutes, and leaves holes the size of a dime. If you need fast results with minimal disruption, polyjacking is the modern answer to settled slabs.
What Is Polyjacking?
Polyjacking, also called polyurethane foam lifting or foam jacking, is a concrete leveling method that uses an expanding two-part polyurethane foam injected beneath a settled slab. As the foam expands, it fills the void under the concrete and creates upward pressure that raises the slab back to its original position.
The process uses much smaller holes than traditional mudjacking, typically about the diameter of a nickel. The foam cures within 15 minutes, meaning you can walk or drive on the surface the same day in most cases.
Unlike mudjacking slurry, polyurethane foam is extremely lightweight. It adds virtually no weight to the soil beneath the slab, which makes it an ideal choice in areas where the underlying soil is already under stress or where added load could cause further settlement.
The foam is also waterproof and does not wash away, shrink, or decompose over time. Once it cures, it stays in place permanently.

Why Choose Polyjacking?
- Fastest cure time of any slab lifting method
- Smaller, less visible access holes than mudjacking
- Lightweight foam adds no stress to underlying soil
- Waterproof material resists erosion under the slab
- Ideal for areas near structures where weight matters
- Still far less expensive than full concrete replacement
Polyjacking vs. Mudjacking: Which Is Right for You?
Both methods lift settled concrete. The right choice depends on your job, your timeline, and your budget. We help you choose during the free estimate.
| Factor | Polyjacking (Foam) | Mudjacking (Slurry) |
|---|---|---|
| Cure / wait time | ~15 minutes; same-day use | 24 to 48 hours to drive on |
| Access hole size | Nickel-sized (~5/8") | 1 to 2 inch diameter |
| Material weight | Very light; no added soil stress | Heavy; dense slurry fill |
| Water resistance | Waterproof; will not wash away | Can erode if drainage unresolved |
| Upfront cost | Higher per square foot | Lower per square foot |
| Best for | Speed, tight areas, near structures | Large surface areas, cost-sensitive jobs |
Our Honest Take
Neither method is always better. For driveways and large patios where cost matters, mudjacking is often the smarter choice. For stoops, garage floors near a foundation, or any job where you need to use the surface the same day, polyjacking is hard to beat. We will tell you which makes more sense for your specific situation before we quote it.
How a Polyjacking Job Works
-
1
Assessment and Hole Marking
We walk the settled area with you, assess the degree of settlement, and mark the injection hole locations. Placement is calculated to give us even coverage across the entire void beneath the slab.
-
2
Drilling the Access Holes
We drill small holes through the concrete, roughly the size of a dime. These are much smaller than mudjacking holes and will be barely noticeable after patching.
-
3
Foam Injection and Lifting
We inject the two-part polyurethane foam through the holes. The components react and expand beneath the slab, filling the void and generating upward pressure. We watch the slab rise and stop when it reaches the correct level. The process takes minutes per section.
-
4
Curing (15 Minutes)
The foam cures in roughly 15 minutes. Unlike mudjacking, there is no long wait. You do not need to keep the area blocked off overnight or reschedule your day around it.
-
5
Hole Patching and Cleanup
We patch the small access holes with a concrete patch mix, clean up the site, and walk you through the results. In most cases the surface is ready to use before we finish packing up.
Where Polyjacking Works Best
Foam lifting excels in situations where speed, precision, or weight sensitivity matter.
Garage Floors and Slabs Near Foundations
The lightweight foam adds no extra load to the soil near your home's foundation. This makes it a safer choice than heavy slurry when working close to structural elements.
Stoops and Entry Steps
Front entry stoops that have pulled away from the house need precise, controlled lifting. The foam injection process gives fine control over how much lift is applied and where.
Pool Decks
Pool decks often have limited equipment access. Small holes and compact injection equipment make polyjacking easier to perform in tight spaces around pools and landscaping without tearing anything up.
Time-Sensitive Driveways
If you need your driveway usable the same day, polyjacking is the answer. The same-day cure means no overnight blockade and no rescheduling vehicles.
Patios Where Aesthetics Matter
Smaller access holes mean smaller patches. On decorative or finished concrete surfaces where hole visibility is a concern, polyjacking leaves a cleaner result.
Areas with Drainage Problems
Because the foam is waterproof, it does not erode over time even if the drainage issue beneath the slab is not fully corrected. It provides a more durable fill in wet or moisture-prone areas.
Polyjacking Questions
Is polyjacking permanent?
The foam itself does not shrink, decompose, or wash away. Once cured, it stays in place. Whether the lift lasts long term depends on whether the underlying cause of settlement is addressed. If a drainage issue continues to erode soil beneath the slab, re-settling can occur. We will flag any drainage concerns during the assessment.
Will the holes show after the job?
The access holes are small and will be patched. You will likely see a slight color difference where the patches are, especially on newer concrete. This is cosmetic and not structural. It typically blends in over time as the concrete weathers.
How does polyjacking compare to replacement cost?
Polyjacking is more expensive per square foot than mudjacking, but both are significantly cheaper than full concrete replacement. Replacement involves demolition, haul-away, forming, pouring, and curing. Polyjacking does none of that. For a slab in good structural condition that has simply settled, polyjacking is almost always the better financial decision.
Does the foam work in cold weather?
Polyurethane foam is more tolerant of cold temperatures than mudjacking slurry, which requires soil temperatures above freezing to cure. Polyjacking can typically be performed in cooler conditions, though extremely cold ground temperatures can affect foam expansion. We will advise based on the time of year you call.
Can you lift any concrete with foam?
The slab needs to be structurally sound. If the concrete is heavily cracked and broken into multiple moving pieces, neither foam lifting nor mudjacking will create a stable, uniform surface. We will assess the condition of your slabs during the free estimate and let you know if lifting is the right approach or if replacement makes more sense.
