Rockfall Barrier Contractor

Canyon Creek Flexible Barrier

Rockfall Barrier Systems for Safe, Reliable Protection

GeoStabilization International is the rockfall barrier contractor of choice for transportation corridors, rail lines, utilities, and coastal or alpine routes exposed to rockfall hazards.

For more than 20 years, our design-build teams have delivered flexible, hybrid, and rigid barrier systems that intercept falling debris and protect the traveling public, while minimizing closures and community impact. Using rope-access crews, limited-access drills, and engineered rock anchor foundations, we install barriers designed to meet site-specific energy and deflection criteria and integrate seamlessly with draped or pinned mesh.

Why Choose GSI as Your Rockfall Barrier Contractor

  • Turnkey Design-Build: In-house geotechnical engineers and rope-access installers deliver one accountable partnership from modeling through commissioning.
  • Rapid Mobilization: Nationwide coverage enables fast response for emergency stabilization and tight construction schedules.
  • Engineered Certainty: Bar and strand anchor foundations with verified free and bond lengths, corrosion protection, and full performance testing.
  • Access Anywhere: Rope-access teams, limited-access drills, casing systems, and helicopter logistics for remote or steep terrain.
  • Safety and Quality Management: Comprehensive safety, traffic-control, and testing programs with documentation that meets or exceeds industry standards.

What Are Rockfall Barriers?

Rockfall barriers are engineered containment systems composed of posts, ropes, and high-strength nets or mesh anchored into competent ground. These systems absorb and dissipate the energy of falling rock, protecting roads, rails, and structures below. Each barrier is modeled for site-specific energy and deflection criteria to ensure predictable, long-term performance.

Our Rockfall Barrier Capabilities

  • Attenuator Fences: A draped upper net connected to a lower energy-absorbing fence, which is ideal for long slopes where material must be guided into catchment areas with limited toe foundations.
  • Catch Fences: Flexible post-and-net systems rated for defined energy levels and deflection limits to stop falling blocks safely.
  • Hybrid Systems: Combine flexible elements with localized rigid features or berms to handle mixed energy levels and limited right-of-way conditions.
  • Rigid Barriers and Parapets: Structural components used where minimal deflection is permissible or flexible systems are impractical.
  • Debris-Flow Barriers: Flexible systems for mixed rock, soil, and water movement in gullies or channels.
  • Integration with Mesh and Scaling: Draped or pinned mesh and pre-installation scaling operations to remove loose blocks and optimize system performance.
  • Inspection, Cleanout, and Rehabilitation: Routine condition assessments, debris removal, testing, and component replacement to sustain design performance.
  • Foundation Expertise: Design and installation of bar or strand anchors for post footings, crest ties, and intermediate supports with corrosion protection and drainage detailing to match service life.

How GSI Delivers Rockfall Barrier Projects

Geological mapping, trajectory and energy analysis, and consequence ranking to determine system layout and fence class.

Selection of system type, attenuator, catch, hybrid, or rigid, with defined post spacing, net and rope details, and acceptable deflection targets.

Rope-access and limited-access drilling using down-the-hole or top-hammer methods; installation of anchors and concrete or steel foundations.

Installation of posts, plates, nets, brake elements, and tie-ins to mesh or drainage features; proof, performance, and creep testing per specification.

As-built documentation, inspection plans, and cleanout protocols to ensure continued system effectiveness.

  • Right-Sized Solutions: Designs that balance safety, cost, and site constraints.
  • Durability: Corrosion-resistant materials and engineered detailing for coastal, alpine, and freeze-thaw environments.
  • Nationwide Coverage: Local responsiveness backed by deep experience in rockfall protection and slope stabilization.

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.

Emergency Rockfall Mitigation for Mining Operations

I recently interacted with some of your rockfall division guys. I have never seen an outfit as competent on safety measures nor any contractors who worked as hard as your guys do. During the work, I was in a room with your guys and some other contractors, and your guys were head and shoulders above the rest in all aspects.
