Ground Set Installation

Ground Set installations are the strongest and most common form of flagpole installation. They require burial of the flagpole shaft in a concrete foundation to a depth equal to 10% of the mounting height.

All standard Flagpoles shown on this site are designed for Ground Set foundations. Each flagpole is shipped at 10% over listed Mounting Height.


NAAMM’s Metal Flagpole Manual offers basic suggestions on foundation measurements in firm, dry soil only using dry tamped sand and 3000 PSI concrete. Soil conditions vary by site. Exact foundation requirements should be verified by a Structural Engineer with knowledge of soil conditions in your locality.
