GeoStabilization International® Establishes Bridge Division

GeoStabilization International’s Bridge Division expands GSI’s ability to deliver time-critical bridge rehabilitation and construction services by applying cutting-edge technologies and approaches developed through decades of emergency geohazard mitigation and bridge rehabilitation/construction experience.

By leveraging our extensive Soil Nail, Micropile, Shotcrete, Compaction Grouting, and GRS construction capabilities, our Bridge Division can solve budget, access, and design challenges most bridge rehabilitation or construction projects face. Our innovative approach to bridge substructure rehabilitation enables us to reduce project cost, schedule, road closures, and environmental impacts. As with our geohazards mitigation services, GSI Bridge Division provides 24-hour on-call response to bridge emergencies.


Bridge Rehabilitation
GRS-IBS Bridge Construction








Over the last fifteen years, GeoStabilization has amassed a considerable bridge rehabilitation resume, and GSI’s founders were also instrumental in developing the Geosynthetically Reinforced Soil-Integrated Bridge System (GRS-IBS), designing and installing the first of these structures in the world. More recently, the FHWA has promoted GRS-IBS technology as one that can provide numerous benefits over conventional bridge construction. Through a newly-formalized strategic partnership with US Bridge. GeoStabilization will expand its ability to provide complete, turn-key, design/build GRS-IBS solutions. Since 1930, US Bridge has been a recognized leader in the design and manufacture of steel beam and truss bridges. GSI’s partnership with US Bridge allows us to seamlessly deliver a complete GRS-IBS solution in a fraction of the time more conventional systems or approaches would take.
