Project required installation of 88 high capacity double corrosion protection anchors through the face of an existing cribwall constructed of concrete “lincoln logs.” There were 4 rows of anchors with the top row 50’ above ground. Longest anchors were 60’ long. A special climbing platform was designed and constructed to access the anchors from a narrow bench. Also, 1300 rock bolts were required on a ledge above the cribwall. Bolts are 15’ long set with polyester resin cartridges.
