Pile Foundation
Pile foundation, a kind of deep foundation, is actually 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 desired depth by either end bearing or skin friction.
Pile foundations are underground structures that support a building. Piles are long pillars that extend downwards into the ground to keep the building above them stable. They are typically used in situations where the top layer of soil is weak and unable to hold the weight of the building.
