Sunken concrete patios, uneven sidewalks, cracked driveways—these aren’t just eyesores. They can be dangerous tripping hazards and signs of deeper problems below the surface. At Perma-Seal, we specialize in long-term concrete leveling, and one question we hear all the time is:
“Should I go with mudjacking or your PolyLevel® system?”
Let’s break down the difference between mudjacking and PolyLevel®, and explain why PolyLevel® is the smarter, cleaner, and longer-lasting choice for homeowners in the greater Chicago area.
What Is Mudjacking?
Mudjacking, sometimes called slabjacking, is a traditional method for raising sunken concrete slabs. The process involves:
- Drilling large holes (1.5″ – 2″) into the concrete
- Pumping a heavy slurry made of water, dirt, and cement underneath the slab
- The pressure of the mixture lifts the slab back into place
While mudjacking has been around for decades, it comes with serious limitations.
What Is PolyLevel®? (Polyurethane Foam Injection)
PolyLevel® is a modern, high-tech alternative that uses lightweight polyurethane foam. The process is faster, cleaner, and more effective:
- Small holes (about ⅝” diameter) are drilled into the slab
- The expanding foam is injected beneath the slab, filling voids and lifting it with precision
- The foam cures in minutes and is ready for use within hours
Perma-Seal exclusively uses PolyLevel® because it solves the same problem better in every way.

Mudjacking vs. PolyLevel®: Key Differences
Feature | Mudjacking | PolyLevel® |
---|---|---|
Hole Size | 1.5" to 2" | ~⅝" (nearly invisible) |
Material Weight | Heavy cement slurry | Lightweight polyurethane |
Water Content | High (can shrink/erode over time) | No water—won’t shrink or erode |
Cure Time | 1–2 days | 15 minutes to 1 hour |
Longevity | Shorter lifespan; may settle again | Permanent, waterproof, erosion-resistant |
Precision | Lower accuracy | Highly accurate leveling |
Environmental Impact | More materials & waste | Eco-friendly, minimal material use |
Disruption | Messy, long drying time | Clean, quiet, fast |
