Mudjacking is a repair technique for lifting slabs
and other concrete structures
that have settled over time and also provides a less expensive and less disruptive method for repairing your settled concrete than removing and replacing it.
Spark’s Concrete Lifting
pumps a tested, engineered “slurry” material underneath the settling concrete. As the mixture is pumped underneath the concrete, it fills voids and creates pressure on the concrete that lifts it upwards back into place and creates a solid, stable fill.
