"We had our concrete floors raised as they have settled over the years. Joey and Derrick were the team that did the raising. Fantastic professionals and excellent workmanship. They not only answered our questions but explained why and how the foam worked. I was a home builder for 10 years and can recognize good workman. These two were outstanding. If you need foundation work or concrete floors lifted, give Innovative a call. DON'T SETTLE FOR ANYTHING LESS."

Concrete Leveling questions, answered by experts

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.

Costs range from $500 to $1,500, depending on the size and condition of the area.

Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The total drying time can vary depending on the size of the project. Because the slurry mixture contains cement, it needs to harden fully to prevent the concrete slab from shifting under added weight. You should avoid walking on the concrete or placing heavy items like furniture or vehicles on the surface until it has fully set. Your concrete contractor can provide a precise timeline. As a point of comparison, if you opt for polyjacking, the polyurethane foam can dry in minutes, but it's recommended to wait about an hour before use.

The timeframe is generally a few hours, allowing for immediate use post-hydration, ensuring minimal disruption to surrounding activities.

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