What is Pile Foundation? Types of Pile Foundation

In this type of pile, the loads pass through the lower tip of the pile The bottom end of the pile rests on a strong layer of soil or rock Usually, the pile rests at a transition layer of a weak and strong slayer As a result, the pile acts as a column and safely transfers the load to the strong layer...
