MAT Foundation (or) Raft Foundation
Mat foundation is otherwise called as Raft Foundation and its working principle is similar to Shallow foundation. Mat foundation is preferred for large space where separate footings are not possible to construct due to overlapping condition. Generally, Mat foundation's footing will extend over a large area. The main reason why the Mat adopted by most Engineers is Mat will distribute loads equally to prohibit differential settlement. Mat is considered when the soil condition is so Poor & week.
