The Diamond Pier is a solid pin pile foundation designed for deck support that reaches deep into the ground without digging holes or pouring concrete! Installation is simple. The precast concrete head is installed at the ground surface, and steel bearing pins are driven through the head and into the ground using simple hand-held tools. This is the best way to install a reliable and durable foundation that will last the lifetime of your deck structure. Minimal digging required, Limited Lifetime Warranty. Proudly made in the USA. New offset style, accepts 4x4, 4x6 & 6x6 deck support posts. Can be installed using a large sledge hammer or the custom driver tool. Doing a single project? There is no need to purchase the custom driver tool, Many standard pointed bits that fit 30# - 60# Electric Hammer tools will easy slide inside the pins closely enough to speed up installation.
