Results
Restored safe access to the spillway inlet gate and abutment road.
Provided long-term stabilisation of over 23,000 sqft of slope with minimal environmental impact.
Successfully safeguarded dam infrastructure and personnel from future rockfall hazards.
Delivered a rapid and effective remediation that maintained uninterrupted dam operations
Project
Solution
Mobilised a geohazard specialist team with rope access expertise.
Installed 300 rock bolts and dowels ranging from 8 to 20 feet to secure loose rock masses.
Deployed helicopter support for mesh installation, coordinated precisely with rope access technicians.
Conducted targeted manual scaling to remove unstable rock and minimise future rockfall risks.
Project
Challenges
Unstable slopes with unfavourable, intersecting joint conditions in Seminoe granite.
Environmental risks, including freeze–thaw cycles, precipitation, and heavy snowfall.
Restricted access to rock faces positioned above critical dam infrastructure.
Requirement to carry out helicopter-assisted mesh installation safely and precisely.
Project
Overview
A rockfall event at Seminoe Dam in Wyoming dislodged angular cobbles and boulders from steep metamorphic slopes, blocking access at the right abutment spillway inlet road. Geovert was engaged to remediate the hazard and restore safe access.
The works included rock scaling, the installation of approximately 300 mechanical and grouted anchors, and helicopter-assisted mesh placement across 23,000 square feet of steep, jointed granite slopes
