House raising and companies in New Jersey

House raising (a.k.a house lifting, house elevating and house jacking) is the process of lifting a house and building a new, or extending the existing, foundation below it. During the elevation process most houses are separated from their foundations, raised on hydraulic jacks, and held by temporary supports while a new or extended foundation is constructed below. The living area is raised and only the foundation remains exposed to flooding.
