RAFT FOUNDATION
A raft foundation is a combined footing that covers the entire
area beneath a structure and supports all the walls and columns.
When the allowable soil pressure is low, or the building loads are
heavy the use of spread footings would cover more than one half
of the area and it may prove economical to use mat or raft
foundation. They are also used where the soil mass contains
compressible lenses or the soil is sufficiently erratic so that the
differential settlement would be difficult to control.
