GSI installs debris flow barriers, horizontal drains, soil nails, and erosion control systems before seasonal atmospheric river events.
With 8,000+ completed projects and 24-hour emergency response, GeoStabilization International brings unmatched expertise to California's geohazard challenges.
California’s seismic activity, steep terrain, wildfire burn scars, and extreme rainfall events create some of the highest geohazard risks in the nation. Common California geohazards we mitigate include rain-induced landslides and post-wildfire debris flows, rockfall hazards impacting highways, rail corridors, and developed hillsides, and seismically driven slope instability and lateral spreading. We also address coastal bluff erosion and retreat, hillside development stability challenges, and foundation settlement or structural movement caused by earthquake activity and variable soil conditions.
Engineered Geohazard Mitigation Solutions in California
Slope Stabilization Systems: Soil nails, ground anchors, and retaining structures engineered for seismic performance
Rockfall Protection Systems: Rock bolting, scaling, draped mesh, and impact barriers for transportation and infrastructure corridors
Landslide Mitigation & Repair: Geotechnical evaluation through permanent stabilization construction
Deep Foundation & Underpinning Solutions: Micropiles and helical piers designed for challenging California soils
Emergency Geohazard Response: Rapid stabilization following storms, wildfires, or seismic events
