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.

Generally speaking, push piers—or steel piers—are the best option for underpinning, as they reach down to solid bedrock to find support for your foundation rather than relying on soil, which could be subject to the same issues as the soil directly below your foundation. However, the best underpinning method for your home depends on your location, how far down the bedrock is, and the type of soil in your area. Helical piers are usually the best option for sandy soil or in areas where the bedrock is too deep to use steel piers.

There is no real alternative to underpinning, although mudjacking and polyjacking are other repair methods that can add support from underneath your foundation. Rather than placing supportive piers under your structure, these involve pumping a material under your slab to lift a sunken section back into its original position. Polyjacking, in particular, is sometimes a suitable solution for stabilization issues under slab foundations, but underpinning is often accepted as the best and most permanent solution.

Polyjacking and mudjacking can both be good solutions to sinking concrete, depending on your situation. Polyjacking, which uses expanding polyurethane foam to lift concrete, is a better option than mudjacking because the foam weighs less and won’t contribute to additional sinking. Polyjacking can be a suitable solution for any sinking concrete slab, while mudjacking is normally only a good option for non-structural concrete, like sidewalks, patios, pool decks, and concrete driveways. However, polyjacking costs much more—as much as $25 per square foot, compared to the maximum of $6 per square foot you’d pay for mudjacking.
