Pile foundations are deep foundations. They are formed by long, slender, columnar elements typically made from steel or reinforced concrete, or sometimes timber. A foundation is described as 'piled' when its depth is more than three times its breadth.

- If highly compressible soil is present at shallow depth.
- If the structure is located near the river bed or sea shore etc, pile foundation is suggested to secure the structure form the possible scouring.
