The shallow foundation is used for founding depth is less than the width of the footing and less than 3m. Shallow foundation is used when surface soils are sufficiently strong and stiff to support the dead loads & imposed loads. The following types are including this foundation. Pad foundation Strip foundation Raft foundation Stepped foundation Deep foundation This foundation is used to construct low bearing capacity soil in soil layers. The founding too deeply below the finished ground surface their base bearing capacity to be affected by surface conditions. This is usually at depth grater than 3m below ground level. The following types are including this foundation. Pile foundation Pier foundation Pad foundation Figure 3 -Pad foundation are isolated foundation. This is required to support reinforcement concrete columns or steel pillars or detached brick masonry piers. When designing a column foundation, the area of square foundation is taken by dividing the total column load by the safe bearing capacity of the soil.
