GeoStabilization International provides expert rockfall scaling services to improve slope safety and reduce geohazard risks across Canada. Rockfall scaling is a critical component of rockfall mitigation, especially in areas where steep terrain, fractured rock, or climatic conditions increase the likelihood of unstable material detaching from a slope. In regions such as British Columbia, Alberta, and parts of Atlantic Canada, scaling helps protect transportation corridors, infrastructure, and communities.
Rockfall scaling involves the controlled removal of loose or unstable rock and debris from a slope, cliff face, or cut. By removing these hazards proactively, GSI enhances slope stability and reduces the potential for rockfall events that threaten public safety. Scaling may be performed manually, mechanically, or through specialized techniques, depending on site conditions and access constraints.
GSI selects scaling methods based on geology, slope geometry, and project objectives:
Highly trained rock technicians remove loose material using scaling bars, pry tools, jacks, or airbags. This method provides precision in areas where equipment access is limited.
Excavators, drills, and other specialized equipment remove rock at a larger scale, improving efficiency on accessible slopes or high-volume areas.
When large blocks pose a significant risk, controlled breaking methods are used to reduce mass and eliminate hazards.
GSI’s rope-access technicians perform scaling on steep or vertical slopes, offering safe and controlled removal where mechanical equipment cannot operate.
Rockfall scaling is a process used to remove loose rocks and boulders from a steep slope or cliff face to reduce the risk of rockfall. Rockfall scaling provides several key benefits:
One of the primary benefits of rock scaling is improved safety. By removing loose rocks and boulders, the risk of rockfall is reduced, which can prevent injuries or even fatalities in areas where people work or travel.
Rockfall can cause significant property damage, including damage to buildings, infrastructure, and vehicles. Scaling a slope can help to reduce the risk of such damage by removing unstable rocks and boulders.
Scaling can also help to increase the overall stability of a slope or cliff face. By removing loose rocks, the remaining rocks are less likely to move, which can help to prevent future rockfall events.
By proactively removing loose rocks and boulders, scaling loose rocks can help to reduce maintenance costs associated with repairing damage caused by rockfall.
Rockfall scaling can help to protect the environment by preventing rocks from falling into streams or rivers, which can have a negative impact on aquatic ecosystems. It can also help to prevent erosion and protect habitats of endangered species.
Safety is the foundation of every rockfall scaling operation. At GeoStabilization International, rock scaling is performed exclusively by SPRAT-certified Rockfall Remediation Technicians trained to work safely at height in steep, unstable, and access-limited terrain.
GSI’s Rope Access Program has earned annual recognition since 2018 from the Association of Geohazard Professionals as a best-in-class safety program. Technicians follow strict rope access procedures, redundant fall protection systems, and task-specific safety protocols to control risk while removing unstable rock. These measures protect workers, the traveling public, and infrastructure below, ensuring rockfall scaling is completed safely and efficiently under challenging conditions across Canada.
