Compare Mudjacking vs Polyurethane Concrete Raising

During mudjacking, workers drill 2-inch to 5-inch holes into the concrete, then pump in a mixture known as slurry. The slurry, which usually consists of water, dirt and cement, fills the voids and raises the slab to its original level. Once the surface is level, the drill holes are refilled with concrete.
