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.
Uses of Pile Foundation
There are different situations when a pile foundation is used. Followings are the main cases where pile foundation use is desirable.
- If a high groundwater table exists beneath the structure.
- If the superstructure load is high and non-uniform.
- Pile foundation is economic than other proposed foundation types.
- 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.
- If a canal or deep drainage systems pass near the structure, pile foundation is suggested.
- If soil condition is very poor and it is not possible to excavate the soil up to the desired depth.
- If it becomes impossible to keep the foundation trenches dry by any measure due to heavy inflow of seepage.
