Understanding Rockfall Mitigation

What is rock mitigation

Rockfall mitigation combines hazard assessment, slope scaling, reinforcement, and catchment or barrier systems to reduce rockfall risk to an acceptable level

When you need rock mitigation services

It is used when loose blocks, ravelling faces, or debris flows create a rockfall risk that no longer meets geotechnical risk criteria and must be brought under control

Pinned & Draped Mesh Systems

Our mesh installations span hundreds of thousands of square metres across North America. Utilizing industry-leading systems from Geobrugg, Trumer, and Maccaferri, our solutions are engineered to stabilize slopes in all terrain conditions. Whether you’re protecting transportation corridors, residential developments, or natural landscapes, our installed pinned and draped mesh solutions offer cost-effective and environmentally sound solutions for slope instability.

Rock Bolts & Dowels

Leveraging various drilling techniques with our fleet of specialized equipment, our technicians can install any bolt or anchor your project requires. Our expertise and attention to detail ensure the integrity and dependability of installed elements—providing durable solutions for a range of applications.

Rockfall & Debris Flow Barriers

GRW has installed some of the largest rockfall and debris barriers in North America. Designed to withstand the volumes and impacts of debris flows and rockfall events, these specialized barriers provide reliable protection for construction sites, highways, hydroelectric facilities, pipelines, and bridges. Our safety-first approach sets the industry standard for high-impact debris flow barriers in the Pacific Northwest.

“No reports of injury or near misses were recorded during the project. The work undertaken was discharged with professionalism using equipment fit for purpose. The project was finished on time and on budget. We would not have any problems recommending GRW for geotechnical difficult access projects.”

“Throughout the project, they demonstrated how their crew was capable of moving and installing large and cumbersome materials on dangerous slopes with both a high level of safety and precision and without the use of heavy machinery. Their innovative approach was a major contribution to the success of the project."
