"Jacob D and Lenard S provided great service. Professional and friendly. Made sure I knew what was going on and answered questions. Treated my home and my family with respect and didn't damage anything, which not all contractors seem concerned about. I have some additional basement work that will need to be complete and I will definitely be using Innovative again."

Concrete Mudjacking questions, answered by experts

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.

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.

Pros often use mudjacking or polyurethane foam injection to level a sunken concrete patio. Both methods lift the slab by filling voids beneath it. After properly compacting the soil beneath it to prevent future settling, the concrete may need to be removed and re-poured for severe sinking.

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

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.
