Mudjacking and PolyRenewal are both concrete lifting solutions that are meant to lift a settled slab back into place. Mudjacking is the older method of the two, and also a lot more well known. However, just because something is well known doesn’t mean that it’s good. Mudjacking has been around for a very long time, so most contractors swear by it because it’s what they are used to. It’s also incredibly cheap because the material used to lift the slab is cement, which is a cheap material to buy. PolyRenewal uses polyurethane foam, and not only does using this material make for a more convenient installation process, it also makes the repairs last longer than in mudjacking. The cement used in mudjacking can erode and it can disintegrate with time. Once this happens, your slab will settle once more. Polyurethane is a synthetic material that is completely waterproof, so it doesn’t get negatively impacted by water. As a matter of fact, it can deter water from reaching the soil and causing further erosion. The cement used in mudjacking is rough and heavy, so the soil underneath it can shift away under its weight. Polyurethane, on the other hand, is lightweight and causes minimal disturbance to the soil. The holes drilled to inject polyurethane foam are also smaller than those drilled for mudjacking, so contractors that use PolyRenewal are able to work with weak concrete as well. PolyRenewal is better than mudjacking because it addresses all the problems that appear in mudjacking repairs. Your concrete is something you should only have to repair once, so choose Foundation Recovery Systems if you’re interested in PolyRenewal.
