Foundation and support system for manufactured structures

A foundation and support system for supporting at grade level, a manufactured structure with a floor, longitudinal frame members beneath the floor, and perimeter walls wherein the structure is supportable over an excavated area having footings, the structure including flexible foundation walls which decoratively enclose the excavated area at the perimeter walls and connect to back fill, the support system comprising:

• a plurality of vertically adjustable supports which can be fixedly mounted on the footings in support of the longitudinal frame members of the structure and removably attached thereto whereby the weight of the structure can be fully supported over the excavation at about grade level;
• a plurality of vertically disposable foundation wall panels having an upper edge, and a lower edge with an intermediate panel portion therebetween, said upper edge having an upper flange and said lower edge having a lower flange wherein said foundation wall panels can be disposed vertically under the perimeter walls of said structure by attachment of the upper flange thereto with fasteners and wherein the lower flange is adapted to be supported in the excavated area and can be covered with the backfill;
• said foundation wall panels being shaped to have an arcuate intermediate panel section offset laterally from the shortest straight distance between the upper and lower edges and whereby the foundation wall panels serve as a flexible retaining wall to retain backfill of the structure to grade, said foundation wall panels being able to flex to accommodate small movements of the structure in strong winds without breaking or pulling said fasteners out, said foundation wall panels acting as a spring tiedown around the structure that adds stability to the system.
