'My first building project utilizing rammed aggregate piers from Ground Improvement Engineering was in 1999. Since that time they have provided ground improvement solutions for a number of building projects that I have been involved with. I've found their rammed aggregate piers to be excellent, cost-effective alternatives to deep foundation systems or soil corrections, resulting in reduced construction time, simplified foundation systems, and cost savings for owners.”

Stephen Hearn, P.E., Structural Group Leader, LHB Corporation (Minneapolis, MN)

'I have been directly involved in a street and bridge project in Sioux Falls where the Geopier Rammed Aggregate Pier system was utilized. The Geopier elements were for street construction as well as bridge approach embankments. The existing subgrade was between two wetlands that required 3,300 Geopier elements to improve the subgrade to a usable condition. Ground Improvement Engineering designed the Geopier system that would meet the load requirements. Installation of the Geopier elements was completed in an efficient and timely manner even considering the limited access to the work area. I would not hesitate to use Ground Improvement Engineering and Geopier Rammed Aggregate Pier systems in the future.'
