Yes, we believe polyurethane foam injection is better than mudjacking. Mudjacking is an older method for leveling an uneven concrete slab. Today, most concrete leveling jobs are done using polyurethane foam injection for the following reasons:

The mudjacking slurry used to raise the slab is heavy because it contains cement, sand, soil, etc. Because of this it has the potential to make the problem even worse because the slab might have become uneven because weak soil was unable to support it. If so, adding more weight to the soil in the form of a cement slurry isn’t going to help.
The mudjacking slurry is prone to erosion if there’s poor drainage under the slab.
The holes used to inject the mudjacking slurry under the slab are at least 2 inches wide. Compare this with the dime-sized holes used with polyurethane foam injection.
Mudjacking is a messy process and then it takes 2-3 to dry and harden. This means downtime.
Yes, mudjacking is still being done today. However, we view it as a temporary fix, at best.
