Systems and methods for preventing lateral soil migration into a void space of a lifted foundation

A system for resisting lateral soil migration beneath a foundation lifted above a ground surface, the system comprising:

• a plurality of skirts that defines a perimeter of the foundation, wherein each of the plurality of skirts comprises a first portion, a second portion, and a third portion, wherein a first side of the first portion of each skirt defines an interior of the perimeter of the foundation and a second side of the first portion of each skirt defines an exterior of the perimeter of the foundation,
• wherein the first portion of each skirt is structurally secured to a slab lifted above the ground surface, wherein the lifted slab is formed within the interior of the perimeter of the foundation,
• wherein the second portion of each skirt circumscribes a void between the lifted slab and the ground surface, wherein the second portion is configured as a barrier between the void and soil at the exterior of the perimeter of the foundation, and
• wherein the third portion of each skirt is set in the ground surface, wherein the third portion is configured to permit vertical movement and resist lateral movement;
• and
• one or more anchors protruding from the first side of the first portion of each skirt, wherein the one or more anchors of each skirt are embedded within the lifted slab, wherein the first portion of each skirt is structurally secured to the lifted slab via the one or more anchors.

A system for resisting lateral soil migration beneath a foundation lifted above a ground surface, the system comprising:

• a skirt, wherein vertical dimensions of the skirt corresponds to a vertical height to which a slab will be lifted, wherein the skirt comprises a first portion, a second portion and a third portion,
• wherein the first portion of the skirt is configured to be structurally secured to the slab,
• wherein the second portion of the skirt is configured to correspond to a vertical height to which the slab will be vertically lifted from the ground surface after forming the slab on the ground surface, and wherein the second portion is configured to be beneath the ground surface during forming of the slab and at least a portion thereof to be raised above the ground surface after the slab is vertically lifted from the ground surface, and
• wherein the third portion of the skirt is configured to be set in the ground surface both during forming the slab and after the slab is vertically lifted from the ground surface, wherein the third portion is configured to permit vertical movement and resist lateral movement;
• and
• one or more anchors associated with the skirt, wherein the one or more anchors are configured to structurally secure the skirt to the slab.
