Diamond Pier Foundation Systems are structurally rated footings for decks, screen porches, gazebos, pergolas and more. This system is made up of a pre-cast concrete head and 4 load bearing pins that provide your structure with greater uplift and lateral resistance. The Diamond Pier models are equivalent to common traditional poured footing sizes and are code compliant with the IRC. Taking only minutes to install each one, builders can finish projects days faster, leaving no messy jobsite. Builders and their customers love Diamond Pier Foundation Systems.
