Get matched with top concrete mudjacking pros in Charlestown, NH

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.

The method involves lifting settled concrete using pressurized cement slurry via drilled holes. This solves uneven surfaces and prevents further settling.

Mudjacking can be an expensive foundation repair process, but in many cases, it’s well worth the investment. This is especially true if you’re lifting a portion of sunken foundation slab back into place. In that case, mudjacking can help avoid major structural damage and even home collapse by restoring the integrity of your structure with minimally invasive procedures. Mudjacking a concrete patio, walkway, or sidewalk can be worthwhile because it removes tripping hazards and makes your outdoor area more aesthetically appealing.

The polyurethane used for polyjacking will expand and cure in 15 to 30 minutes. After that point, your slab will be safe to walk on and even drive on in the case of a sidewalk or concrete driveway. Double-check with your concrete lifting specialist to confirm a curing timeline, as products can differ.
