Aggregate pier installation is a ground improvement technique that constructs dense columns of compacted stone. The columns are installed in groups in soft soil to increase bearing pressure and mitigate settlement under structural footings.

GP3 Geopier Rammed Aggregate Piers (RAP) were used to increase the allowable bearing capacity up to 6,000 psf while maintaining the total static settlement to less than 1 inch. Increased bearing capacity allowed for smaller spread footings and reduced concrete and steel costs.
