Polyurethane Concrete Leveling in Janesville & Southern Wisconsin

Lift sunken, uneven concrete with a fast, clean polyurethane foam solution. Bothun's Concrete Leveling serves residential, commercial, and municipal properties throughout Janesville, Madison, Milton, Beloit, and surrounding Wisconsin communities.

When soil settles or empty spaces develop beneath a concrete slab, the concrete above can begin to sink and become uneven. Polyurethane concrete leveling lifts the existing slab instead of requiring the entire surface to be removed and replaced.


Small injection holes—as small as a dime—are created in the concrete. Polyurethane foam is injected beneath the slab, filling the space below and helping raise the concrete back toward the proper level.



Because the foam and injection process are contained, there is no need for sloppy onsite slurry mixing. The result is a cleaner repair process with minimal disruption to the surrounding property.

Why Choose Us

Polyurethane Foam Benefits

Why Choose Polyurethane Foam for Concrete Leveling?

Polyurethane leveling provides several advantages when existing concrete can be lifted instead of completely replaced.

01

Clean, Controlled Installation

The polyurethane foam is contained during installation, eliminating the need for messy onsite slurry mixing and reducing the potential for spills.

02

Lightweight Material

Polyurethane foam is much lighter than traditional slab-lifting slurry. That means less additional weight and pressure are placed on the soil beneath the repaired concrete.

03

Water-Resistant

The polyurethane foam used by Bothun's Concrete Leveling is more water-resistant than traditional mudjacking slurry.

04

Fast Return to Use

Polyurethane leveling minimizes downtime after the repair, allowing repaired concrete to be returned to use quickly.

05

Made With Recycled Material

Approximately 30%–50% of the polyurethane foam used by Bothun's Concrete Leveling is made from recycled material.*
