A Geopier Rammed Aggregate Pier is a high-stiffness column of densely compacted aggregate installed in the subgrade using a specially designed mandrel. The pier transfers building loads through compressible soils, increasing bearing capacity and reducing settlement at a fraction of the cost of deep foundations.
Commercial buildings, industrial pads, tank foundations, embankments, infrastructure, and any structure sited on soft, loose, or liquefiable soils. Ground improvement is also a strong fit for seismic retrofit work in California and other high-seismicity regions.
Compared to driven piles or drilled shafts, ground improvement is typically faster to install, lower cost, and generates less vibration and disruption. It supports conventional shallow footings or slabs and shortens the construction schedule for many project types.
WGI installs Geopier technologies across California, Nevada, New Mexico, and Arizona, including the Los Angeles, San Diego, Las Vegas, Phoenix, and Albuquerque metro areas.
