Abstract
A system for forming a movable slab foundation has a slab foundation, at least one support surface, at least one lifting member, at least one support sleeve, and an engagement device carried by the at least one support sleeve. The at least one support sleeve is encased within the slab foundation and its lower end is positioned in abutting contact with the at least one support surface. The at least one lifting member is inserted through the at least one support sleeve. The at least one support sleeve and the slab foundation are moved upward axially along the length of the at least one lifting member. The engagement device is engaged with the at least one lifting member, thereby securing the slab foundation and the at least one support sleeve at a desired height.
