A floating slab foundation is named because it sits or "floats" atop the ground. It is the easiest and least costly foundation to build. Floating slab foundations work well in warm climate areas where there is little to no ground freezing that can affect the floating slabs integrity. Floating slab foundations have piers that are relatively shallow, in most cases less that 2 feet deep. The rest of
. the slab is generally 4 to 6 inches thick with wire mesh embedded to give it strength. There is far more detailed information at this website http://www.michaelholigan.com/Departments/TVShow/seg_tscript.asp?ts_id=5424&text_type=M&text_page=1.
