In civil engineering, concrete leveling is a procedure that attempts to correct an uneven concrete surface by altering the foundation that the surface sits upon.

Mudjacking, Mr. Murray said, costs about $3 a square foot with a minimum charge of about $300 and can also be used to lift sunken areas of driveways, garage floors and even brick or concrete stoops.

Tom Roman, president of All Jersey Mudjacking, a sidewalk repair company in Perth Amboy, N.J., said that when extended periods of cold weather were followed by only short periods of warmer days, the ground underneath the concrete or slate freezes solid and stays frozen.
