Diamond Pier® Foundations are pre-engineered foundation systems for all types of secondary residential structures, including decks, porches, walkways, sheds, stairs, and gazebos. The system installs in minutes without excavation, and you can frame immediately. These foundations allow builders to dramatically increase their production—simply set the concrete head, drive the pins, fasten a standard post bracket, and start building. Downtime and scheduling headaches are eliminated, and there's no need to dig deep holes, pour concrete, or repair landscape. The job site and yard are left clean and damage-free.
Based on nearly three decades of use by public agencies across the United States, the latest Diamond Pier models, DP-50 and DP-75, are designed for use in normal construction conditions, and follow a simple load chart and basic knowledge of local soils. See our published Residential Load Chart.
