"On July 1st (2021), Mel and Stephan from Innovative Basement Authority dug a 30'x18" trench by hand to bury our sump pump discharge pipe. They installed a freeze valve, 30' of 5" PVC, and a discharge grate, exactly where we asked to place it. They had to dig right next to the garage foundation, so this was no easy feat. They also made short work of removing a 4'x4' concrete pad for us. The guys were very courteous, punctual, and seriously hard-working. They did an exceptional job, and in just half a day, I was able to check 1 more item off my honey-do list! We are hoping to hire Innovative Basement Authority for some garage floor concrete work in the near future. Thanks IBA! Brian & Terri MacDonald"
Concrete Mudjacking questions, answered by experts
Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs.
Concrete leveling is absolutely worth it if you have sunken concrete slabs and want to restore them to level, especially if the slab is part of your home foundation. Concrete leveling is less than half the price of replacing concrete sidewalks, patios, walkways, and pool decks, and it’s about a quarter of the cost of replacing a foundation. If you also treat the underlying problem, it can be a worthwhile and permanent solution.
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.
Costs range from $500 to $1,500, depending on the size and condition of the area.
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.
