Get matched with top concrete mudjacking pros in Akutan, AK

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.

Generally speaking, push piers—or steel piers—are the best option for underpinning, as they reach down to solid bedrock to find support for your foundation rather than relying on soil, which could be subject to the same issues as the soil directly below your foundation. However, the best underpinning method for your home depends on your location, how far down the bedrock is, and the type of soil in your area. Helical piers are usually the best option for sandy soil or in areas where the bedrock is too deep to use steel piers.

Mudjacking can take 24 to 72 hours to cure enough to resume normal use. Because the slurry mixture contains cement, it needs to fully harden to ensure that added weight won’t shift the concrete slab before it has completely set. Your concrete contractor will be able to tell you when you’re free to use your concrete surfaces again after mudjacking.

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