Abstract: To prevent lateral soil migration beneath a slab foundation lifted over a ground surface, a plurality of skirts are placed in the ground surface to define a foundation perimeter. A slab foundation is formed within an interior space of the foundation perimeter. The plurality of skirts are secured to the slab foundation via one or more anchors protruding from a portion of each skirt toward the interior space of the foundation perimeter. The slab foundation is raised above the ground surface to create a void that permits vertical expansion of soil without subjecting the slab foundation varying forces associated with the dynamic nature of the soil. The plurality of skirts are raised along with the slab foundation and operate as a barrier that circumscribes the void space and resists lateral soil migration into the void from the exterior of the foundation perimeter.

Abstract: To form a new structurally suspended slab or to raise an existing slab for a structural foundation, structural supports are placed in the ground. The structural supports are attached to lifting assemblies, which are also installed in the slab. Actuation of the lifting assembly allows the slab to be raised and/or lowered, thereby forming a suspended slab over a void of a desired size. Existing slabs may be repaired using similar techniques.
