Poly Leveling vs. Mudjacking
What’s the Difference — and Why It Matters
When concrete settles, homeowners often hear two terms: mudjacking and polyurethane foam concrete leveling (also called polyjacking). Both methods aim to raise sunken concrete slabs, but the material and results are very different. At Midwest Foam Works, we only use poly foam leveling because it provides cleaner, longer-lasting results for Wichita homeowners and businesses.
