Geopier Rammed Aggregate Pier Applications & Regional Case Studies

Presented By: Keithe J. Merl, P.E., 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 and; 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 Penguins Arena and various projects in the strip district.
