A concrete pier is a foundation element suitable for many types of structures but most commonly used for timber frame post and beam buildings.

A: A helical pier is a steel shaft with helices, similar to a large screw, that provides a foundation support for various types of structures. The shaft is usually square and manufactured in 5 foot sections.: Because each helical pier is installed to a specific load requirement rather than a specified depth, each application is different. A typical depth is about 20 feet, but can be as shallow as 10 feet and as deep as 60 feet or more.
