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 concrete pier typically consists of a round or square concrete pillar supported at the bottom by a footer piece which serves to spread the load carried by the pier. The pier is placed or cast with the footer below the frost line and its top end above the ground surface.
Deck piers support the beams that create the joist spans for a deck. This is the foundation of the deck and if not properly installed will result in failure of part or the entire deck. Unlike a concrete footing that distributes the weight of the structure over a large area, piers concentrate the load to a small area.
