Why Choose GSI as Your Rockfall Mitigation Contractor

 

Turnkey Design-Build

In-house geotechnical engineers and rope-access field crews deliver one accountable partnership from assessment through installation.

Rapid Mobilization

Nationwide coverage ensures fast response for emergencies and tight construction windows.

Specialized Access

Rope access, limited-access drills, compact rigs, and helicopter support for steep, remote, or constrained slopes.

Proven Systems

Engineered barriers and fences with verified energy ratings, plus durable draped mesh and bolting systems that perform where conventional methods fall short.

Safety and Quality Management

Work-at-height, environmental, and traffic-control programs that meet or exceed industry standards.

Our Rockfall Mitigation Solutions

  • Geologic Assessment and Monitoring: Detailed mapping, risk ranking, and instrumentation to identify and track unstable rock masses.
  • Scaling Operations: Hand or mechanical scaling to safely remove loose blocks and unstable wedges, coordinated with live traffic management.
  • Rock Bolting: Patterned or spot bolting to stabilize rock masses with tensioned or untensioned anchors; compatible with mesh or shotcrete facings.
  • Draped Mesh Systems: High-strength mesh to control raveling and channel debris into safe catchment zones.
  • Containment and Catchment Systems: Attenuator fences, catch fences, ditches, and embankments designed to intercept and dissipate debris energy.
  • Debris-Flow Barriers: Flexible systems for mixed rock and debris movement in steep gullies and channels.
  • Emergency Response: Rapid stabilization following rockfall events, freeze-thaw cycles, storms, or excavation-induced instability.

Client Reviews

Rockfall Mitigation in Virginia

I wish I had been smart enough to let you design the rock mitigation. You and your team turned in an excellent performance. The work ethic of your team impressed everyone on our side of the table. Most companies print a slogan on their company clothing. However, your folks demonstrated every hour that they “Work Hard or Go Home”. You sent us a world class construction team – thanks!

Rockfall Mitigation and Removal in Wyoming

Richard, I wanted to take a quick minute and thank you and Courtney and the awesome crew that you sent here to take care of our huge rock. Courtney, John, and Andrew are some of the hardest working people I have had the privilege to be around. Their attention to safety professionalism, and never quit attitude was amazing to watch. Even when things did not go our way they were committed to finishing the job. I appreciate you sending these great guys to help us out and look forward to the opportunity to work with you again in the future.

Rockfall Mitigation Support for Mining Operations

As told by GSI Rockfall Division Director: “I am at the [mine] now and the truck with the equipment from the warehouse just arrived. Environmental issues are extremely important in the mine so any equipment arriving on site has to be pressure washed and cleaned. Although they ask this of every contractor that arrives on site, they always seem to have to do a secondary washing here with their own people (just the way it always seems to turn out). Our people at the warehouse did such an awesome job of cleaning and taking the client’s concern to heart that they do not have to do a secondary cleaning and complimented us for such a great job.
