What is a pin pile?
A pin pile is a small diameter pipe, ranging from 2 to 6 inches, typically galvanized, that is driven into the ground to the point of refusal using a pneumatic pile driver. These piles are a more inexpensive approach to addressing or preventing any foundation settlement issues on both new and existing structures. Typically pin piles are used on projects requiring lighter loads transfers. When used in a retrofit application, a bracket will be used at the top of each pile to connect the pile to the foundation or footing. For a new construction application, a different type of bracket will be installed prior to pouring the footing.
