Concrete leveling Any process—such as mudjacking or polyurethane foam injection—used to raise and realign sunken, uneven concrete slabs.
Concrete leveling is designed to eliminate trip hazards by lifting off-level flags back to their original grade without demolition. While highly effective for private backyard pathways and warehouse floors, it is not a standard or widely accepted method for clearing NYC DOT sidewalk violations. The city typically mandates replacing the uneven flags to guarantee long-term safety and proper water drainage.
