Types of Foundation and their Uses. Following are different types of foundations used in construction: Shallow foundation Individual footing or isolated footing Combined footing Strip foundation Raft or mat foundation Deep Foundation Pile foundation Drilled Shafts or caissons *Types of Shallow Foundations Individual Footing or Isolated Footing Individual footing or an isolated footing is the most common type of foundation used for building construction. This foundation is constructed for single column and also called as pad foundation. The shape of the individual footing is square or rectangle and is used when loads from the structure are carried by the columns. Size is calculated based on the load on the column and safe bearing capacity of the soil. The rectangular isolated footing is selected when the foundation experiences moments due to the eccentricity of loads or due to horizontal forces. For example, Consider a column with a vertical load of 200
