Diamond Pier® foundations are uniquely suited for use in public projects such as boardwalks, pavilions, overlooks, and bridges. Installed without excavation, they’re also great to have on hand in the maintenance garage for quick, small or temporary constructions projects.  They have been used successfully and repeatedly over the last two decades by Federal, State and Municipal clients across the US, and they provide significant compression, uplift and lateral load capacity.

Using a wide variety of Pier sizes and Pin lengths specific to the strength of the soils and project loads, installation is simple, and can be accomplished by public works crews, general contractors or volunteer groups without special training. The Piers have a range of available embedded anchor bolt configurations to attach to post or beam brackets, and there are also 4-bolt models, allowing for steel plate, I-beam connections or column leveling.

The smaller piers can be used with a load chart and a basic knowledge of local soils, or an engineer’s stamp of Pier capacities can be provided for the larger piers for most states in the US.  For stamped foundations capacities, soils information from a local licensed geotech and complete project loading information must be submitted to Pin Foundations, Inc.   (See Capacities

Diamond Piers® are sold direct, through design and supply companies, or through local stocking or special order retailers.
