Diamond Pier Footings
Diamond Pier Footings
Diamond Pier Footings use a concrete block and galvanized steel pins to distribute weight over a larger area, similar to a tree root system. This design provides strong, stable support while minimizing ground disturbance.
A jackhammer is recommended for installation, ensuring the pins are driven securely into place. Before using, check with your local building department to confirm approval for your project.
DP-50s come with 50" pins, plugs, and caps.
DP-75s come with 63" pins, plugs, and caps.

Other items used with Diamond Piers
If you own your jackhammer, this bit will allow you to install DP pins easily, and without damaging them. If you decide to rent a breaker/hammer, many rental places will have this bit available to use, just besure to ask!
Diamond Pier Driving Bit
Diamond Piers will need some sort of post base to secure a post or framing to the footing. We recommend this base for its stability, ease of attaching to Diamond Pier and the framing, and the ability to use it with a 6x6 or triple 2x beam without any modification.
