Geopier introduced the Rammed Aggregate Pier® (RAP) technology to the industry in 1989 as an Intermediate Foundation® solution that cost clients 30 to 50 percent less than deep foundations.
Our RAP ground improvement technologies are constructed by applying direct vertical ramming energy to densely compact aggregate to form high stiffness engineered elements and increase the lateral stress that improves surrounding soils. This process provides superior support capacity, increased bearing pressure (up to 10,000 psf), and greater settlement control for all soil types.

As Geopier made a global expansion, we expanded our ground improvement technologies to include rigid inclusions, slope reinforcement and rail subgrade stabilization to meet every day geotechnical challenges worldwide.
Geopier rigid inclusions are ground improvement elements used to transfer loads through weak, compressible soils to deeper underlying competent soils. Our rigid inclusions are comprised of plain concrete, aggregate/grout mixture or cement-treated aggregate. Geopier rigid inclusions are used to increase bearing capacity (up to 12,000 psf) and minimize total and differential settlements in soft soil profiles, such as peat or organics, soft silt, or soft clay.
