Floating Ground Foor Slabs.

Floating ground floor slabs gain their support direct from the hardcore and/or sub-strata and are jointed off between any main structural columns or walls (see Fig. 9.47). The slabs are not supported by the foundations and thus float on the hardcore or sub-strata.

As a guide, see Tables 11.4 and 11.5 which indicate a  number of nominal slab thicknesses and meshes, and the typical ground conditions and assumed depressions for which they should be designed.
