Local know-how
Why foundations move in Long Island
Long Island is built on sandy glacial deposits over a shallow aquifer. On the South Shore, the water table can sit only a few feet below the surface; on the North Shore, hills and slopes send runoff toward foundations. Sand can wash out or settle when water moves through it.
Many homes were built from the 1920s to the 1960s, including large post-war developments, and many have block foundations and finished basements. Superstorm Sandy in 2012 flooded thousands of South Shore homes, and saltwater and saturated soil left many foundations cracked or settled.
Local contractors handle settling footings, cracked and bowing walls, sagging beams and the drainage work that keeps water away from the house.
