Mat Foundation Construction Process

A mat foundation is used when the subsoil is weak and column loads are so heavy that the conventional spread footings cover more than 50 of the building area.

Mat foundation construction process.

To begin constructing the solid slab raft foundation the vegetative top soil original soil is removed then the soil left behind is compressed. Raft or mat foundations a raft foundation also called a mat foundation is essentially a continuous slab resting on the soil that extends over the entire footprint of the building thereby supporting the building and transferring its weight to the ground. At those places we use mat foundations to distributes the whole loads of the structure to the soil when the area of the footing was increase than the soil load bearing capacity will also increase because this foundation reduces the stress on the soil at the same place. The raft foundation is a very commonly used type of foundation system.
