CONCRETE LEVELING GUIDE
Mudjacking vs. Polyurethane Concrete Lifting
Both approaches aim to support and raise settled concrete, but they use different materials and installation techniques. The right choice depends on the project—not simply which method has the better sales pitch.
Traditional mudjacking
Mudjacking generally pumps a cementitious slurry beneath concrete through drilled access holes. Ask the provider about the material used, hole size, added weight, curing expectations, and suitability for your slab.
Polyurethane lifting
Polyurethane systems introduce expanding material beneath the slab in controlled amounts. Installers often use smaller access holes, but material selection, training, placement, and monitoring still matter.
Questions that lead to a better decision
Ask why the proposed method fits your slab, how voids and drainage were evaluated, what elevation is achievable, when the area can be used, what patches will look like, and what the warranty actually covers.
The slab condition still controls
Neither method restores badly deteriorated concrete. Extensive cracking, spalling, reinforcement problems, or structural concerns may make replacement the more appropriate recommendation.
