A Raft Foundation is described as a raft in the sense that the concrete raft is cast on the surface of the ground which supports it, as water does a raft, and the Foundation is not fixed by foundations carried down in the subsoil. That is why the raft Foundation can be done in many types of soil, like clay, dolomite, or any soil with collapsible potential. It is a solid reinforced concrete structure that support the load of what is built on top of it, with limited deflections or movement in the top structure. Nowadays this type of Foundation can compete with the traditional stripfooting in that it is compatible with any type of soil and because of accuracy, cost and time effectiveness
