1. “How does Concrete Raising differ from Mudjacking?”
Concrete Raising uses a cementitious slurry to raise slabs and fill the voids beneath them. This process of raising concrete with concrete results in a repair that is impervious to water and therefore a more permanent fix. So permanent, that warranties for work done with this process exceed warranties provided on new concrete installation by two-to-four (2-4) times.
Mudjacking, as the name implies, utilizes a mixture of topsoil, water and admixtures which is hydraulically pumped into a hole drilled in a slab of sunken concrete. In as much as the material being used to raise the slab is the same material that is under the slab, erosion overtime typically does not result in a long-term fix.
