A power transmission company faced three landslides that threatened to shut down a key access road to their transmission lines. The company contacted GeoStabilization International® to develop a repair plan that would not only stabilize the landslides, but provide up to four additional feet of roadway width at this rugged, mountainous site.
GeoStabilization’s engineers developed a repair plan using Geosynthetically Confined Soil (GCS™) services wall founded on reticulated SuperMicropiles™ with a BioWall® facing. In the truncated base of the wall, Self-Drilling SuperNails™ extended to the wall face to prevent toppling. The plan not only met the strict environmental constraints at the site, but also significantly reduced the amount of concrete required at this difficult access site. After the wall was constructed and seeded, native wildflowers and other vegetation took over, completely obscuring the BioWall® facing.
GeoStabilization International is proud to partner with the City and County of Denver to perform periodic rockfall mitigation and maintain an inventory of rockfall hazards at Red Rocks Amphitheatre.
