Piling refers to the installation of structural piles deep into the ground as a foundation of a structure. Piling is the most common foundation method used for high-rise constructions where there is a risk of rapid settlement of soil due to the extreme dead load of the building.
Pile foundations have practically extended the boundaries of construction. They allow engineers to build higher-than-ever and stronger-than-ever structures. Piles foundations have opened doors to offshore and underwater constructions as well.
Although the origin of piles is not determined, however, they have been in use since ancient times. People used timber piles under their houses near rivers or lakes due to weak subsoil. There are examples of Romans using timber piles as foundations in bridge construction. The large monasteries built in the East Anglian fenlands during the Middle Ages were built on piles of oak and alder. Timber was the only material used for piles for a long time due to its strength, lightweight, durability, ease of cutting, and handling.
Generally following four types of materials are used for piling.
Many construction sites can use piling, as it provides many benefits. Some of these are mentioned below:
