Mudjacking vs. Polyurethane Concrete Leveling in Milwaukee & Southeastern Wisconsin

If your driveway, sidewalk, or patio is sinking, you’ve probably come across two solutions: mudjacking and polyurethane concrete leveling (polyjacking). Both lift sunken concrete back into place, but the results are not the same.

In Milwaukee and Southeastern Wisconsin, where freeze–thaw cycles and heavy soils are common, the difference matters even more. Here’s what homeowners should know.

Mudjacking: The Old Way

Mudjacking involves drilling large holes and pumping in a heavy slurry of soil, sand, water, and cement under the slab.

Why it falls short in Wisconsin:

Heavy material often causes the slab to sink again in clay-rich or weak soils.

Moisture and freeze–thaw cycles (a big issue in Milwaukee winters) break it down quickly.

The holes are large and noticeable after patching.

It’s usually a short-term fix.

Polyurethane Concrete Leveling: The Modern Solution

Polyurethane concrete leveling (polyjacking) uses expanding foam instead of mud. Small, dime-sized holes are drilled, and lightweight, water-resistant foam is injected beneath the slab to lift it back into place.

Why it’s better for Southeastern Wisconsin homes:

Lightweight – won’t add extra stress to already soft soils.

Water-resistant – holds up against snow melt and spring rains.

Freeze–thaw durable – won’t shrink, crack, or wash away like mudjacking slurry.

Smaller holes – cleaner finish with less visible patching.

Fast curing – walk or drive on it within hours.

Long-lasting – often 20+ years with proper drainage.

Which is Best for Milwaukee Homeowners?

Mudjacking may look cheaper upfront, but in Southeastern Wisconsin’s climate it rarely lasts. Polyurethane concrete leveling is stronger, cleaner, and built to handle the conditions we face every winter.

If you want a solution that’s built for Wisconsin homes, polyjacking is the clear winner.

FAQs

Q: How long will poly-leveling last in Wisconsin’s climate?
Polyurethane foam is water-resistant and handles freeze–thaw cycles, so it often lasts 20+ years.

Q: Is polyjacking more expensive than mudjacking?
Yes, but it’s also more durable. Many Milwaukee homeowners see it as an investment that saves money in repeat repairs.

Q: Can it fix driveways, patios, and sidewalks?
Yes. Most sunken slabs can be repaired with polyurethane foam unless the concrete is severely broken.
