In New York City, property owners are responsible for the sidewalk in front of their buildings. Cracked or uneven slabs can bring NYC DOT violations, and where a sidewalk sits over a vault, the problem is often structural — corroded steel, deteriorated concrete and water finding its way into the space below.
LINE handles both sides of that problem: the visible sidewalk and curb, and the vault structure and waterproofing underneath, sequenced so the building stays accessible while the work is done.
