These intermediate foundation innovations are the best alternative to massive over-excavation and deep or driven pile foundations. (If they weren’t, we’d invent something else.) All utilize a distinctive vertical impact ramming energy to deliver superior strength and stiffness; all can be installed using replacement or displacement methods. The Rigid Inclusion methods are piers blended with concrete or grout, and in the case of Armorpact are confined with high-density plastic. The RAP systems are more versatile. They provide greater support capacity, better settlement control, and are a better economic value than the historical vibro-stone column method.
Adding to the suite of ground improvement methods are the Geopier SRT® and Geopier X1® systems. Geopier SRT is the patented Plate Pile method for slope reinforcement and repair using arrays of steel or aluminum elements. Our X1 system is a hybrid method of our Geopier GP3® System and Impact methods, supporting deep foundations of more than 45 feet.
Our newest system, Geopier Spike, is a solution to stabilize railway beds without major disruption to the railway structures or schedules of your clients.
