It is considered as one type of shallow foundation and is useful in controlling the differential settlement.
Raft mat foundation is used in those places where we have less bearing capacity of the soil.

Conventional methods use manual calculations and charts.
The mathematical modeling of continuous mat foundations has been correlated with laboratory testing providing confidence that typical finite element modeling.
The selection of the type of mat foundation is made based on the applied load on the foundation system.
Mainly there are two methods to design the raft foundations.

A raft or mat foundation is a large continuous rectangular or circular concrete slab that carries the entire load of the superstructure and spreads it over the whole area beneath the building.
The net pressure increase in the soil under a mat foundation can be reduced by increasing the depth d f of the mat.
Reinforced concrete footing are designed based on column loads and moments at base and the soil data.
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.

Design of mat foundation.
This approach is generally referred to as the compensated foundation design and is extremely useful when structures are to be built on very soft clays.
