"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
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.
Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The exact time can vary depending on the size of the project. Because the slurry mixture contains cement, it must fully harden to ensure that added weight from walking, furniture, or vehicles won't shift the concrete slab. A professional contractor can advise you on when the surface is safe to use. For comparison, if you use polyjacking instead, the polyurethane foam can dry in just a few minutes, but it's best to wait about an hour before use.
Yes, expanding foam (also known as polyurethane foam) can lift concrete. This approach, called polyjacking, involves injecting the foam rather than concrete slurry to fill voids and raise the concrete slab back into place. It’s often faster and requires smaller drill holes than traditional mudjacking, though it may come at a higher cost. Some contractors also prefer polyjacking over mudjacking for more damaged and delicate slabs.
Charges correlate with surface size, settlement depth, and access, often yielding significant savings over concrete replacement.
The timeframe is generally a few hours, allowing for immediate use post-hydration, ensuring minimal disruption to surrounding activities.
