Notice of Meeting

Announcement from the BWH Section of the

Association of Environmental & Engineering Geologists

Date: Wednesday 11/16/2016


Baltimore MD – Washington DC – Harrisburg PA

 TOPIC: Geopier Rammed Aggregate Pier™ Applications & Regional Case Studies

 PRESENTER: Ms. Shana Carroll, P.E., Northeast Preconstruction Manager; GeoStructures, Inc.

Rammed aggregate pier systems are a ground improvement technology that can be used to increase bearing capacity and control settlement of buildings, tanks, Retaining walls and embankments to close tolerances.  Depending on site requirements, RAP systems can be installed using replacement (Geopier GP3®) or displacement (Geopier Impact®) methods. RAP systems are used to reinforce good to poor soils, including soft to stiff clay and silt; loose to dense sand; organic silt and peat; variable, uncontrolled fill; and soils below the ground water table. They can be used as an alternative to deep foundations or over-excavation, and provide cost and time savings on sites where poor soils and/or existing undocumented fill are a concern in terms of bearing capacity and settlement. This presentation reviews fundamental Geopier design and construction techniques and includes regional case studies such. Projects discussed include the National Cancer Institute’s Advanced Technology Research Facility located in Frederick Maryland and underlain by karst geology in the Piedmont Province, the Gaylord National River Ballroom located in National Harbor, MD in the Coastal Plain Province, and the George Mason University Fenwick Library in the Piedmont Province.
