In my opinion, polyurethane polymers have far surpassed the capabilities of mudjacking. The injection port size of polyurethane is a fraction of that made by mudjacking and, the polymer products are also a fraction of the weight. The polyurethane expands and has a better quality of void fill; whereas the mudjacking grout seems to build mounds but never really expand in the crevices in the soil. The light weight composition of polymers makes it much less likely to settle in the future when compared to the weight of the grout used in mudjacking. Also the concrete / structure lifting capability of the two component foam in addition to the power of the concrete lifting rig is unparalleled. To me the most impressive part of polyurethane is the deep injection process. Until now we have only supported in spite of failing soils; now we have the ability to completely stabilize the underlying soil using an array of different polymers. This is also something that it's predecessor was unable to do properly. Polyurethane is also used in seawall repair since it does not erode over time. Mudjacking grout is a cementicious material that breaks down over time with enough water. This is my quick take on the two and welcome all opinions and thoughts to correct and/or agree with this logic. Happy lifting and have a blessed week!
