Rock Scaling

Rock scaling is the foundation of GeoStabilization International’s rockfall mitigation services and is performed on nearly all our projects. Our Rockfall Remediation Technicians (RRTs) hold both S.P.R.A.T. and I.R.A.T.A. rope-access certifications, ensuring industry-leading skill and safety. We offer manual, mechanical, and remote scaling, along with blasting capabilities, including innovative Autostem technology, to remove loose rock and stabilize slopes. Since 2018, our Rope Access Program has earned the Association of Geohazard Professionals’ Safety Recognition as a best-in-class program.

What Is Rockfall Scaling?

Scaling removes loose rock and boulders from steep slopes or cliff faces to reduce rockfall hazards caused by weathering, erosion, seismic activity, or human impact. This technique improves slope stability, safeguards infrastructure, and protects travelers in high-risk areas such as roads, railways, and building sites.

Our Scaling Methods

  • Manual Scaling – Scaling bars, airbags, or hydraulic jacks for precise removal.

  • Mechanical Scaling – Specialized drills and excavators for large or complex areas.

  • Remote Scaling – Drones and robotic equipment for difficult-to-access slopes.

  • Blasting – Targeted rock removal using controlled blasting, including Autostem technology.

Our team is ready to help with your next project.

Benefits of Rock Scaling

  • Improved Safety – Reduces rockfall hazards and protects workers and travelers.

  • Property Protection – Prevents damage to infrastructure, vehicles, and facilities.

  • Increased Stability – Removes unstable material, reducing future failures.

  • Lower Maintenance Costs – Minimizes repairs from rockfall damage.

  • Environmental Protection – Prevents debris from entering waterways and reduces erosion.

Assessment & Design

We respond to rockfall events quickly. Using UAVs, 3D photogrammetry, and advanced modeling software (including RockPack, RocPlane, SWedge, RockFall, and Plaxis), our engineers analyze failure areas and design tailored, context-sensitive solutions.

Safety Commitment

Our rope-access crews follow rigorous safety protocols, use advanced fall arrest and redundancy systems, and operate with minimal environmental disturbance.

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!

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!

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.
