Concrete Leveling with High Density Polyurethane
High-density polyurethane concrete leveling was first introduced in Europe in 1989, then soon after in the United States. The process was initially used on large DOT projects but is now cost-effective enough to use on smaller scale industrial, commercial, municipal, and residential projects.
With the proper equipment and materials, the process is relatively simple.
- We use a
ground penetrating radar (GPR)
for void detection beneath the
concrete. This method uses a
high-frequency radar antenna and
advanced signal software to
locate voids and objects beneath
- After locating the voids, a small 5/8" hole is drilled through the damaged concrete slab.
- Using our highly specialized system, polyurethane foam is injected into the void beneath the slab. As it expands, the concrete is raised back into its original position and permanently stabilized. We can precisely raise the slab to within 1/10th of an inch. Additionally, the resistance of lifting the concrete structure compacts the base soils.
- Lastly, the holes are filled, the site cleaned up, and the equipment is removed.
- Due to the short hardening time of the polyurethane material, the concrete surface is ready for use about 15 minutes later. The dense polyurethane material is impervious to water, preventing future erosion problems.

Compared to other concrete leveling methods, polyurethane concrete leveling is more efficient, 75% more economical, 80% faster to complete (and therefore less disruptive), more accurate, and moisture resistant. You can read about all of the advantages here.
