Uplift & Lateral Load Resistance
The uplift anchor assembly extends from the bottom of the pier to the ground surface where it is structurally connected to the shallow foundation. The uplift resistance provided by the Geopier systems eliminates the need for deep foundations or over-sizing of shallow foundations. Lateral resistance of Rammed Aggregate Pier® systems is provided by increased composite friction angle that results in an increased composite friction coefficient for sliding resistance at the base of foundations.
Construction of the Geopier ground improvement solution using vertical ramming energy results in friction angles of 50 degrees. This provides significantly improved design bearing pressures of 5 to 10 ksf or more depending on soil conditions. The improved bearing pressure reduces footing sizes, saving time and money on your project.
