Difference Between Mud and Foam Jacking

Sunken concrete can be a pin to deal with, especially around your home or property. If you’ve been looking into ways to fix it you’ve probably come across two common solutions: mud jacking and polyurethane foam lifting. Both can raise settled slabs, although they work very differently. So, what’s the difference, and which one’s right for you?

Mud jacking has been around for decades. It involves pumping a heavy mixture of mud, water, and cement underneath the slab to lift it up. While it gets the job done, it’s not the cleanest solution. It usually requires bigger holes, it takes longer to cure, and because the material is so heavy, it can lead to more sinking in the long run.

Foam lifting, on the other hand, is the newer, more advanced method. At Boost Concrete, we use waterproof polyurethane foam that expands under the slab, lifting it gently and filling in the gaps where soil has eroded. The foam is lightweight, cures in minutes, doesn’t make a mess and won’t wash away. Therefore, your concrete is ready to use the same day with no long cure times or cleanup needed.

When you consider Manitoba’s heavy clay soil, freeze-thaw cycles, and moisture issues, choosing foam just makes sense. It’s fast, clean, and built to last. Plus, it’s up to 75% cheaper than full concrete replacement.

Whether it’s your driveway, steps, sidewalk or garage pad, we’ve helped hundreds of Manitoba homeowners choose the better fix, and now it’s your turn.
