In this course we will learn about Pile Foundations (Function Based).
Deep foundations are those win which the depth of the foundation is very large as compared to its width. These type of foundations are provided where the bearing capacity of the soil low or negligible, or loads of the building is much more. Deep foundations are not constructed by ordinary methods of open-pit excavations.
