Used to target poor soil zones anywhere in the soil profile in order to increase pier capacities beyond what a regular RAP can achieve.
Rigid Inclusions Precision Grouted RAPs
Precision grouted Rammed Aggregate Pier® (RAPs) Systems are used to target poor soil zones anywhere in the soil profile in order to increase pier capacities beyond what a regular RAP can achieve. A specially equipped Geopier Impact mandrel is used in the installation and placed on the survey pin location with the stone valve in closed position. Pressurized grout is applied at the mandrel tip when the mandrel tip is at the correct elevation where poorer soils are encountered at any level in the soil profile. In all other aspects, precision grouted RAPs are the same as grouted RAPs.
How Can We Do More with GeoSolv Rigid Inclusions than Other Rigid Inclusions?
GeoSolv’s Rigid Inclusion Systems always involve sizeable vertical crowd force, vertical ramming energy and significant lateral stress increase. This action, along with the vertical ramming and heavy crowd pressure with lateral cavity expansion, is unique to GeoSolv and creates unsurpassed system performance. These three factors are essential, as they result in a more highly engineered system with Read More >> improved performance over other rigid inclusion approaches.

Treat up to 16m depths with 400-750mm diameter elements for high loads in loose sand, soft silt and clay, fill, topsoils, and organics, with a combination of a grouted RAP element targeted to the very poor zone and a regular Rammed Aggregate Pier element elsewhere.
