"Installed 7 push piers in two days and was able to raise the foundation of one wall up one inch to level it back with the rest of the house. The crew of Jonathan H, Manuel A and Gerardo T did an efficient and clean job. I was kept informed at every step of the process."

"John is a good communicator. This was a multi step process and needed to dry in between steps. Each day, he let us know how long heâ d be working. He covered to room in a plastic bubble to limit dust to the rest of the house and did an excellent job leaving the basement clean."

"We had the company come out after we had a flood in our basement. They leveled the concrete and sealed the area and we never had a water issue again. They cleaned the area and you never would have known they were there. We even were sent a video of the job! Very impressed and highly recommend"

House Leveling questions, answered by experts

Concrete leveling can last anywhere from five to 10 years or more, and in some cases, it can be a permanent solution. The longevity depends on the method used and whether the underlying cause of the sinking is addressed. For example, mudjacking typically lasts five to 10 years, while polyjacking can last for 20 years or more. It's best to consult a professional for an accurate timeline based on your specific situation and any factors that could cause the issue to recur.

Polyjacking can be a permanent solution to sunken concrete if you also address the underlying issue—like poor drainage—at the same time. The polyurethane material itself can last as long as or even outlast the concrete you’re lifting it with. Your sunken concrete issue will likely return if you don’t couple polyjacking with proper drainage to prevent future soil movement and sinking.

A good slump height really depends on the project, but there is a use for nearly all slump levels. For example, low slumps are best in projects that require structure, such as curbs and roads. High slumps often require additional reinforcement, but they flow more freely into hard-to-reach spaces.

It’s best not to perform mudjacking in the winter unless the ground temperature remains above freezing. Freezing temperatures can cause the slurry to harden too quickly, compromising its strength and longevity. Concrete is also more susceptible to cracking and splitting in cold temperatures, so there’s a higher risk of damaging the slab during the drilling and lifting process in winter.

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.
