 When shallow soil is not strong enough to support the load of a structure, a deep foundation is required. Pipe piles are commonly used for deep foundations and transfer the load from the building to a stronger soil layer deep underground. Load resistance is achieved through skin friction and point bearing. Pipes can be open or closed, with points or plates. If driven with plates, the pipes can be filled with concrete to increase the strength of the pile. Money typically spent on plates, steel bars, and concrete is better spent on larger, thicker piles. The size of pipe piles ranges from a few inches to several feet and can be easily spliced into piles hundreds of feet long.
