System for Forming a Movable Slab Foundation

A system for forming a movable slab foundation, the system comprising:

• a slab foundation;
• at least one support surface;
• at least one substantially vertical support member having a substantially cylindrical hollow body with first and second ends, the first end abuttingly contacting the at least one support surface;
• at least one support sleeve surrounding the at least one support member, the at least one support sleeve having a hollow body with inner and outer surfaces, the inner surface having threads contained therein, the outer surface having at least one reinforcing bar connected to and extending outwardly therefrom, the outer surface of the body also having a plurality of nuts connected to and extending outwardly therefrom, the outer surface of the body and the at least one reinforcing bar being encased within the slab foundation and the at least one support sleeve and the slab foundation being capable of moving axially along the length of the at least one support member;
• a plurality of eye bolts connected to the plurality of nuts and extending upwardly from the slab foundation;
• at least one lifting member surrounded by the at least one support member, the at least one lifting member having a body with first and second ends and a length greater than the desired height of the slab foundation, the first end abuttingly contacting the at least one support surface;
• and
• a locking nut positioned in abutting contact with the second end of the at least one support member, the locking nut having a hollow body with inner and outer surfaces, the outer surface having threads therein adapted to engage the threads on the inner surface of the at least one support sleeve to thereby secure the axial position of the at least one support sleeve and the slab foundation along the length of the at least one support member.

A method for forming a movable slab foundation, the method comprising:

• placing a plurality of support surfaces below an intended slab foundation area;
• placing a plurality of support members in abutting contact with the plurality of support surfaces;
• placing a plurality of support sleeves over the plurality of support members and sliding them down in abutting contact with the plurality of support surfaces;
• forming a slab foundation such that it encases the plurality of support sleeves;
• and
• simultaneously lifting the plurality of support sleeves to move the slab foundation along the length of the plurality of support members to a desired height.
