Rockfall Scaling Contractor

Engineered Rockfall Scaling Solutions

GeoStabilization International is the rockfall scaling contractor of choice when loose blocks, wedges, or raveling debris threaten highways, rail lines, and nearby infrastructure.

For more than 20 years, our design-build teams have executed manual, mechanical, remote, and precision blasting operations across North America, reducing immediate hazard risk, improving slope performance, and keeping transportation corridors open safely and efficiently.

What Is Rockfall Scaling?

Rockfall scaling is the controlled removal of loose or unstable rock from cliffs and slopes to prevent rockfall impacts on people, vehicles, and infrastructure. By proactively clearing hazards and cleaning slope faces, scaling stabilizes the remaining rock mass, improves the performance of containment systems like mesh and barriers, and reduces maintenance frequency.

Our Rockfall Scaling Capabilities

Manual Scaling: SPRAT-certified Rockfall Remediation Technicians (RRTs) use scaling bars, airbags, and hydraulic jacks to dislodge loose rock safely.
Mechanical Scaling: Excavator-mounted tools, drills, and attachments suited for production scaling where safe machine access is possible.
Remote Scaling: UAV reconnaissance and robotic equipment for inaccessible or high-risk slopes.
Precision Blasting: Controlled methods, including Autostem, for removing stubborn or large hazards while minimizing flyrock and traffic impacts.
Source Control Integration: Combined scaling with pinned or draped mesh, rock anchors, shotcrete, or barriers for long-term protection.
Monitoring and Maintenance: Scheduled inspections, cleanouts, and programmatic scaling to maintain corridor safety and extend system performance.

How GSI Delivers Scaling Projects

Rapid on-site evaluation by a qualified geotechnical engineer, including UAV or photogrammetry if needed.

Kinematic and trajectory modeling (RocPlane, SWedge, RockFall, Slide) to target the most critical hazards.

Define scaling approach, access plan, traffic management, and complementary measures such as mesh or barriers; fixed-cost proposals where applicable.

Crews mobilize quickly, sequencing top-down scaling with real-time adjustments and strict safety oversight.

Final inspection, documentation, and maintenance guidance to sustain long-term stability.

Rope Access Safety Leadership

Our Rockfall Remediation Technicians hold SPRAT rope-access certifications and operate under an award-recognized rope-access safety program. Each project includes redundant fall-protection systems, task-specific rescue plans, and coordinated maintenance of traffic (MOT) to protect crews and the traveling public.

The GSI Advantage

Fewer Closures and Faster Schedules: Phased work and efficient access methods minimize disruption.
Integrated Solutions: Scaling combined with mesh, anchors, and barriers for complete hazard control.
Durability: Corrosion-resistant materials and detailing for coastal, alpine, and freeze-thaw environments.
Nationwide Coverage: Local responsiveness backed by decades of geohazard mitigation experience.

Client Reviews

Rockfall Mitigation and Scaling for Mining Operations in Canada

Hey Trevor, I gotta [sic] admit, I was a little worried after our progress on the first day of scaling. I wondered if I’d missed something in analyzing that slope! However, on day two, the guys were able to get the bulk of the loose material down in the two areas I was concerned about. They also installed two prisms into the blocks adjacent to the areas scaled so we can monitor any changes in the slope.
The team who came to site were the epitome of professional, not to mention a lot of fun to work with. There was never any point where I felt they were working unsafely. I am most impressed with the entire operation.
I think we were able to remove 100% of the immediate hazard for that area, and 75-80% of the overall hazard. Job well done!

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!

Rock Scaling for Mining Operations in Georgia

Mr. Aguirre, I want to personally thank you for all the effort you and your crew on site at [the quarry] did for me. You were very accommodating. Special point needs to be given to GSI's safety program and its employees for following them strictly. I would honestly say that your organization is one of the top in safety that I have seen in every rope access industry. Please give a couple extra kudos to Fred and Courtney for putting up with me and observing me in order to keep me out of harm’s way. There is no doubt I slowed down their progress. I wish I could remember the whole crews name for they all deserve praise for the jobs that they do. After only two half days of peeling rock, my back is killing me from pushing that bar around. This is a really hard and dirty job (not to copy Rowe) and its workers deserve the utmost respect from the rope access community. I seriously believe you have one of the nastiest. Right up there with the oil industry. This time spent observing and hands on gave me a plethora of information and understanding. I, of course need to see a few other aspects of your industry, not limited to, but to include: drilling (especially horizontally), rigging and lifting (cranes, helicopters, etc.), explosives, and installations of the final products. I hope that with your efforts and others in your industry we can accomplish this soon. In conclusion, thank you again for all your hard work.
