Why plie is provided

Pile foundation is a type of deep foundation. It is a slender column or long cylinder made of materials such as concrete or steel which are used to support the structure and transfer the load at the desired depth by end-bearing or skin friction. Pile is provided in the following case:

• When the groundwater table is high.

• Heavy and un-uniform loads from superstructure are imposed.

• When the soil at shallow depth is compressible.

• When there is the possibility of scouring, due to its location near the river bed or seashore, etc.

• When there are deep drainage systems near the structure.

• When soil excavation is not possible up to the desired depth due to poor soil conditions.
