Type of Shotform Application:
Project manager Victor Chaisson used approximately 170,000sf of Shotform in rehabilitating this old railroad tunnel (3300' long x 20' high x 16' wide). Six men using ramset fasteners (1 3/4" & 2 1/2") installed roughly 750 sheets of Shotform a day (approximately ten days for total installation). The main tunnel cross section consisted of the existing tunnel lining, j-drain, Shotform, #4 rebar 12" on center, welded wire mesh and a minimum 2 1/2" Shotcrete liner.
