What is the difference between polyurethane foam injection and mudjacking?
Mudjacking is sand, water, and a little bit of Portland cement to give it some stickiness, some cohesion. Without it, it’s just sand. It’s susceptible to erosion, takes on moisture, can fracture, crack and fall apart. Mudjacking was a fine solution when it was the only alternative to tearing your concrete out. But now with the advent of polymers, it’s becoming obsolete.
