For a floating raft foundation, or floating foundation, the foundation has a volume such that, were that volume filled with soil, it would be equal in weight to the total weight of the structure. When the soil is so soft that not even friction piles will support the building load, the final option is the use of a floating foundation, making the building like a boat that obeys Archimedes’ principle; it is buoyed up by the weight of the earth displaced in creating the foundation.
