Lifting Sidewalk Back to Stair Level in De Pere, WI

After many years of water seeping below the concrete, the soil underneath began to wash out. Because of this their concrete slab sunk, detaching itself from the stairs.

To raise the concrete back up, we inject polyurethane foam beneath the slab. This foam has incredible strength and is waterproof, therefore, these homeowners won't have to worry about this happening again.
