True innovation. For any soil situation.

Soft clay or silt.
Loose sand.
Organic soils, uncontrolled fill, high groundwater.

At Ground Improvement Engineering, no matter your soil conditions, we have the unique products and processes to help you succeed. Chief among them: our family of Rammed Aggregate Pier® (RAP) and Rigid Inclusionsystems for soil stabilizationand slope reinforcement.

Rigid Inclusions:

Geopier Grouted Impact® System
Geopier Armorpact® System
GeoConcrete® Columns System

Rammed Aggregate Piers:

Geopier GP3® System
Geopier Impact® System
Geopier X1® System
Geoppier Densipact® System


Geopier Spike™ System
Geopier SRT® System

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.

'At first were somewhat skeptical that Geopier systems could develop adequate bearing conditions in some very challenging environments. After dozens of highly successful projects covering many applications, our firm regularly recommends rammed aggregate pier systems as a cost effective solution to develop increased bearing capacity and settlement control. Just as important, their technical assistance has been highly professional and extremely responsive. They certainly are at the top of our list of soil improvement solutions.'

All of this technology and know-how is backed by more than two decades of engineering design and proven foundation support across the Midwest — and the relentless R&D of Geopier Foundation Company. Our work with Geopier on conception and implementation of new systems like RAP have optimized costs, codes and schedules the world over.

It truly is innovation for almost any soil conditions. Click on the following technologies to consider their application for your upcoming projects.

'I have worked on a significant number of projects with Ground Improvement Engineering over the course of 10 plus years. I consider them a trusted partner and rely on their solutions often when dealing with poor soil conditions and/or moderate to heavy foundation loads. They are reliable and professional and I trust their sound engineering practices.'
