Concrete is heavy! Concrete driveway and sidewalk slabs are super heavy! It is hard to believe that sinking and cracking heavy concrete could be leveled by foam but it can! The foam that is used for concrete leveling and repair is a high-tech blend that uses a two-part system that companies use instead of mud jacking.
Polyurethane Foam that Levels Concrete
Polyurethane foam is part of the two-part system used in Foam Mudjacking. Polyurethane foam is better than the cement, dirt and water mixture that the typical mud jacker uses. Polyurethane foam will not shrink once injected under sinking concrete. In fact, it expands seven feet in all directions to fill every void and space under the concrete slab.
Cracking concrete is a symptom of voids that exist under a concrete slab. The cracks become more pronounced as the concrete sinks lower and lower in an uneven way as the voids under the concrete are not even. Waiting until the cracks are more and more pronounced may seem like a good idea but if you wait too long, your concrete may need to be replaced as it is now too damaged to be repaired.
The Foam that Lifts and Levels is not the Same as Insulating Foam
The foam that is used to lift and repair driveways, sidewalks, basements, steps and porches is not the same foam that is used to insulate your attic. The two-part foam jacking process is sensitive to humidity and temperature. Only an expert who works with the foam that lifts concrete on a daily basis can expertly apply the right parts of the two-part system to ensure the foam that is used to repair the concrete works, sets and expands as it is intended to.
Why Leveling Concrete with Foam is Better than Mud Jacking?
Using foam to lift your concrete is better because:
- Once is it lifted it will stay lifted
- Many mud jacking jobs need to be redone
- Foam jacking is less invasive
- Foam Jacking equipment won’t tear up your lawn
- Foam material is lighter than mud jacking material
- Foam is impervious to the elements and won’t sink like mud jacking material can

Thank you for explaining that waiting too long until the cracks are more and more pronounced may lead to your concrete needing to be replaced as it is now too damaged to be repaired. My father is currently working on building a farmhouse, and he’s looking at using concrete material. I think it’s advisable to seek assistance from a contractor to help him with the concrete leveling.
