In the past, the only solution for sinking sidewalks, patios, steps, or uneven foundations, was to remove the damaged pavement and pour new concrete. This cost a great deal of money and time. There is an alternative available called mudjacking or concrete leveling. This alternative can save money and time by pumping a slurry beneath the uneven concrete section in order to raise it back into place.
Details on the Mudjacking Process.
Small holes are drilled into the uneven concrete and a slurry is pumped through these small holes. The slurry may be composed of various materials, including: sand, cement, soil, limestone, bentonite clay, water, or expanding polymers. The small holes are then filled and finished to match the old slab. The type of slurry used is based on the application, as well, as the company’s preference. The slurry fills-in empty spaces underneath the section and levels it. The slurry solidifies and stabilizes the subsoil over the next 24-hours making it solid and stable again. Prior to a mudjacking process, drain pipes, sewers, and utilities must be located and avoided.
