About Us

Who is Geopier?

Geopier, a division of CMC, is a design-build engineering firm that specializes in ground improvement.  Geopier® developed the first Rammed Aggregate Pier® system in 1989 and has grown its arsenal to include rigid inclusions, slope reinforcement and rail solutions. 

Our goal is to customize a design-build ground improvement system that meets your project pricing and schedule objectives.  This is accomplished through cost-efficient designs that allow for high design bearing pressures (up to 10,000 psf), greater settlement control, and reduced construction schedules.  There is no soil type or structure we cannot handle.
