A casino in Black Hawk, Colorado required stabilization of a 154 foot canyon wall located above a heavily traveled pedestrian area. The rock face was susceptible to falling rock and loose debris, creating a long term safety concern for visitors below. Boulderscape developed a rockfall mitigation solution that combined structural stabilization with an architectural finish designed to preserve the natural appearance of the canyon.
The project encompassed 80,400 square feet of wall surface and included the installation of steel reinforcement and rock bolt anchored structural shotcrete across the entire rock face. Once stabilized, Boulderscape artisans hand sculpted and stained a Pikes Peak Granite finish to replicate the surrounding rock formations and blend seamlessly into the canyon environment.
The project consisted of a 6" thick structural shotcrete section with an average 3" thick architectural relief over a rock bolt stabilization system using a 5,000 PSI mix design. Working at heights exceeding 150 feet, the crew completed the full structural and architectural scope in just 44 days, delivering a durable rockfall protection system while maintaining the natural character of the canyon walls.
