Roadways, Embankment, and Retaining Walls

Transportation structures bring a unique set of problems to the geotechnical world.  

Walls and embankments must address heavy loads and global stability concerns and roadways must be uniformly supported to prevent deformations of the road surface. 

Geopier’s solutions for transportation structures are specifically designed to address these concerns by reinforcing unsuitable bearing soils to improve the engineering properties and meet the design requirements for the project.

Design Benefits

Geopier® ground improvement systems address the key geotechnical design components associated with transportation structures: settlement, bearing, capacity, and global stability.  Geopier offers the only ground improvement technology evaluated by an independent HITEC committee for transportation projects. Our ground improvement systems have supported hundreds of retaining walls and embankment projects throughout the United States.

Schedule Benefits

Geopier’s solutions are rapidly installed, which can help keep your projects ahead of schedule.  Our licensed installers can mobilize multiple rigs and work around the clock to meet any of your scheduling needs.  As an added benefit, there is no need to wait for concrete to cure before starting construction on the transportation structures.

Cost Benefits

Geopier® ground improvement systems provide significant cost savings, particularly for large projects.  Our foundation solutions are typically 20 to 50 percent cheaper than conventional foundation solutions (deep foundations and removal and replacement) and produce minimal spoils which saves on earthwork and haul-off costs.

Global and Local Stability

Geopier soil reinforcement increases the factor of safety against global instability of retaining walls and embankments. The high angle of internal friction exhibited by the Geopier RAPs provides significant increases in the shear resistance, thus improving the factor of safety for global/slope stability.  We also have a solution for shallow slope failures, our patented SRT system.  Please see our Slopes application page for more details.


Geopier®  has developed several custom solutions for existing railroads exhibiting signs of distress.  Our Geospike℠ system is a quick and easy solution for tracks with subgrade issues that can be installed with minimal disturbance to operations and our SRT® system can treat slope instability issues along the track alignment.
