TL;DR
A pier block is a precast concrete footing block, often molded with a socket or metal bracket on top, that supports posts or beams for ground-level decks and sheds without poured footings. The blocks bear on compacted soil or gravel at grade rather than below the frost line, so they only work where frost heave is not a concern.
