Diamond Piers Deck Foundations

Diamond Pier Deck Foundations are precast footing systems that replace traditional dig-and-pour concrete footings. A precast concrete head paired with four galvanized steel pins drives into undisturbed soil, creating a solid, code-compliant base for decks, porches, and other outdoor structures — with minimal excavation and no curing time. Engineered to resist frost heave and distribute load reliably across a range of soil conditions, Diamond Piers let you set footings and start framing the same day. Size Configurations DP-50/50 — Concrete head weighs 50 lb. and anchors with four 50-inch pins. Rated for roughly 3,300 to 4,400 lb. of bearing capacity depending on soil type, covering most standard deck framing jobs. DP-75/63 — Concrete head weighs 75 lb. and anchors with four 63-inch pins. Rated for roughly 4,200 to 6,400 lb. of bearing capacity, built for heavier loads and larger structures. Key Benefits Installs fast with minimal excavation — no digging, forming, or curing Resists frost heave for reliable year-round stability Code-compliant footing for decks, patios, and raised walkways Two size configurations to match your project's structural needs Installation Note: Setting the pins calls for a mid-size breaker hammer fitted with a 1-1/8" hex-shank driving bit — bit sold separately. Replacement caps also available.
