Geopier Rammed
Aggregate Pier® System (RAP’s)
X1® System

Allows for visible inspection of the hole opening and the opportunity to address changing ground conditions as they happen.

The X1® system creates Rammed Aggregate Pier elements using a vertical ramming process, which is a combination of both replacement and displacement methods. The X1® system builds replacement/displacement Rammed Aggregate Pier elements to reinforce good-to-poor quality soils. The system allows for construction flexibility, as well as the ability to build through caving zones. The X1®
system drilling operation allows for visible inspection of the hole opening and the opportunity to address changing ground conditions as they happen. Its performance, flexibility, and cost-effective qualities make it the ideal solution for reinforcing a variety of soils.

How Does GeoSolv Do More with Geopier (RAP) than Other Ground Improvement Techniques?

GeoSolv’s Ground Improvement Systems involve heavy vertical crowd force, massive vertical ramming energy and significant lateral stress increase. This action, along with the vertical ramming and heavy crowd pressure with lateral cavity expansion with lateral stress buildup, is unique to GeoSolv and creates unsurpassed system performance. These three factors are essential as they result in a more highly engineered system with improved performance over other ground-improvement approaches. GeoSolv can work with the worst soils: soft clay, loose silt, peat and uncontrolled fill−not just sandy soils.

GeoSolv offers Ground Improvement Solutions that treat a wider range of soils and offer distinct advantages over other historic ground improvement systems such as deep dynamic compaction (dynamic compaction), stone columns (vibro replacement, vibro stone columns), vibro compaction (vibro flot) and deep soil mixing (DSM). Contact us today to learn more about the advantages that GeoSolv’s Ground Improvement Systems can offer for your project, or to receive an obligation-free proposal for the use of an Innovative Foundation Solution.

GP3
The Geopier X-1 system is constructed by auguring a cavity and vertically ramming lifts of aggregate (gravel or recycled concrete) within the cavity and driving the aggregate laterally into the side walls. The X-1 system is a unique combination replacement/displacement technique that has the ability to build through caving soils to create stiff, rammed aggregate piers. The result of the X-1 installation is superior bearing capacity and settlement control without the need for bulk excavation or deep foundation (piling) systems.

Improve up to 16m depths with 450 to 900mm-diameter elements in sand, silt, clay, fill and trapped topsoil.
