How do rammed aggregate piers work
WebAggregate piers are columns of compacted stone. We install them in groups into soft soil profiles that require densification and reinforcement to support the building loads. We often use aggregate piers for ground improvement projects on sites that have soft clay, silt, or man-made fill soils. WebGEOPIER X1® System. The Geopier X1 ® system creates Rammed Aggregate Pier® (RAP) elements using a patented vertical ramming process which is a combination of both replacement and displacement methods. It is a good fit for sites that are generally efficiently reinforced with pre-auguring in cohesive and clay soils but marginally unstable.

WebGeopier rammed aggregate piers have been used as a soil improvement method in the United States since 1989, and more recently in Europe and Asia. An overview of the Geopier system is presented by Fox and Lien, 2001 [1]. Traditionally, when encountering peat or soft organic soils, engineers design deep foundations or WebRammed Aggregate Piers are a versatile ground improvement solution designed to reinforce poor soils through the use of patented mandrels. These systems are ideal for nearly all soil types and applications. Rammed Aggregate Pier elements can be installed using “drill and fill” techniques (ideal for non-caving soils such as silts and clays ...
