Out of every geotechnical challenge, Geopier® finds a way to make rainbows. Peterson Contractors Inc is working in beautiful Flagstaff, AZ on a new mixed-use complex. Geopier GP3® elements are being installed to reinforce and improve the undocumented loose to medium dense silty sand fill and medium stiff clay soils. Using Geopier Rammed Aggregate Pier® technology saved the owner money (on an otherwise costly remove and replace option) and helped the GC expedite their construction schedule.

A bio-energy facility is expanding in Williams, CA and Foundation Service Corporation worked in the pit shown over a temporary working platform that would otherwise be an open subgrade of soft saturated clay to install Geopier X1® elements through the soft shallow clay and into a competent underlying clay. Uplift harness were installed with some of the elements and embedded into the stiff clay to provide resistance to transient uplift forces to optimize the foundation dimensions and save the owner significant cost on concrete and an alternate over excavation option.

A new school is breaking ground in Sacramento and Geopier Impact® elements are being installed to a depth of 40 feet to treat a site with potential for large liquefaction settlements. The Rammed Aggregate Pier® system is constructing stiff elements to densify and reinforced the in-situ silty sand and sandy silt soils to create a liquefaction resistant composite subgrade below the building footprint. The 1-story school is adjacent to a large municipal utility line. We worked closely with the project team and consultants to implement extensive vibration monitoring equipment to verify the specified vibration limit was not exceeded and ensure the integrity of the utility is maintained.
