Polyurethane concrete leveling contractors inject a liquid resin beneath the sunken slab. The resin expands into a foam, solidifies the soil, and lifts the slab. As a result, polyurethane forms a strong bond with the concrete underside, creating a durable support base that prevents future erosion.
On the other hand, mudjacking contractors pump a cement slurry under the sunken slab to push it back up. While the dried cement provides support, it doesn't adhere to the concrete as effectively as polyurethane. Over time, the cement may settle or wash away, requiring repeated applications. Furthermore, mudjacking requires heavier equipment and longer curing times.
The choice between polyurethane leveling and full replacement depends on your slab's condition. Multiple cracked sections across the entire surface may call for replacement. Conversely, isolated sinking of mostly intact slabs may suit lifting better. In general, polyurethane concrete leveling is less invasive and less expensive than complete replacement.
When estimating concrete leveling job costs, contractors consider a few key factors:
