Concrete Leveling questions, answered by experts

It restores concrete, prevents replacement cost disruptions, reduces trip hazards, and provides stability at a lower cost.

Most projects take 1-3 hours, with immediate usability after completion.

Charges correlate with surface size, settlement depth, and access, often yielding significant savings over concrete replacement.

Many contractors offer warranties for their work. Confirm terms before starting the project.

Polyjacking and mudjacking can both be effective solutions for sinking concrete, but they have key differences. Polyjacking, which uses expanding polyurethane foam, is often considered a better option because the foam is significantly lighter than the cementitious material used for mudjacking. This reduced weight puts less pressure on the underlying soil and lowers the risk of future sinking. Polyjacking is suitable for any sinking concrete slab, while mudjacking is typically only recommended for non-structural concrete, such as sidewalks, patios, pool decks, and driveways. The primary drawback of polyjacking is its cost, which can be up to four times higher than mudjacking—as much as $25 per square foot compared to a maximum of about $6 per square foot for mudjacking.
