"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
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.
Many contractors offer warranties for their work. Confirm terms before starting the project.
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.
Mudjacking restores level surfaces, prevents further damage, and is more cost-effective than a full replacement.
Mudjacking is your best bet for leveling concrete on a tighter budget. It’s less expensive than foam or grout mixture. For smaller, surface-level issues, you could also use a self-leveling compound, which creates an even surface over existing concrete—it’s a budget-friendly option suitable for DIY enthusiasts.
