GeoStabilization was tasked with providing an alternate design/build strategy that required a rockfall protection barrier system at the base of the steep slope, the construction of a 30,750 ft2 soil nail wall, and installation of 4,200 ft2 of Geobrugg TECCO mesh. For the soil nail wall, GeoStabilization installed eight hundred and forty-six (846) each 52mm Hollow Bar Soil Nails “HBSN” totaling 51,250 linear feet. To accelerate this construction phase, GeoStabilization developed a solution that included a flexible barrier system at the crest of the retaining wall and incorporated hollow bar soil nails in the slope stabilization systems. Our optimized designmethodology allowed for improved operational efficiencies by overlapping drilling and shotcrete operations with excavation sequencing for each cut bench.
During the project, two GeoStabilization family members were recognized for their safety and leadership in written form by Barrick safety officials; during the project we received zero citations for MSHA violations.
A Mid-Atlantic state’s Department of Transportation (DOT) and its historical preservation group wanted to repair and rehabilitate a failing rock wall within a town in Appalachia.
