"Our project was to lift and balance a garage floor and long driveway using foam. Marc, Ben and Andrew showed up on time, did a thorough job, explaining the process every inch of the way. They did what was contracted for plus a bit. The cleanup was everything I could have asked for. We were told exactly what possible problems to watch for and what to do about them. A very good experience and a good warranty."

Concrete Mudjacking questions, answered by experts

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.

Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. 

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

Mudjacking is suitable for sidewalks, driveways, patios, and nearly all exterior flat structures. However, it may not suit severely damaged or heavily cracked areas.

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