Ice Jacking

Ice Jacking is the occurrence of water entering the inner sectors of a structural or geographical system, and when frozen expands causing a structural fracture. This process also commonly goes by ice shove, ice heaving, or ice wedging. Ice jacking often affects those living near the shore line during the winter; people have often come home to find extensive damage to their home's structure. The process of ice jacking occurs when the temperature begins to rise, and the pressure within an ice sheet rises. It then cracks, either severely or hairline, creating an open space between the ice. As the ice melts, it fills the cracks and freezes, thus expanding the area of ice. The growing amount of ice begins to add pressure onto the surrounding areas, particularly homes if close to the shoreline. This pressure can demolish a boat dock, and cause severe damage to retaining walls. Ice jacking often affects home owners in Minnesota, Wisconsin, and the entire Northern Great Lake region.
