Winding along California’s scenic Highway 78, Boulderscape sculpted 31,300 square feet of structural and architectural shotcrete into a Julian Granite finish — even hiding the drainage to keep it natural, delivered in 14 days at 36% below traditional construction.

A new soil nail wall was constructed along California's scenic Highway 78 to stabilize the surrounding hillside while preserving the natural character of the corridor. Because the retaining wall would remain highly visible to the traveling public, every aspect of the design was intended to replicate the appearance of the area's native rock formations. Boulderscape's Julian Granite finish was selected to provide a realistic architectural solution that blended seamlessly with the surrounding canyon.
Boulderscape hand sculpted the Julian Granite finish across the entire wall surface, incorporating natural fractures, relief, and rock textures inspired by the local geology. To preserve the uninterrupted appearance of the wall, Boulderscape also developed an innovative top of wall drainage system that eliminated the need for a traditional concrete V ditch, allowing the architectural finish to continue uninterrupted across the entire structure.
The project encompassed 31,300 square feet of wall surface consisting of an 8" thick structural shotcrete section with an average 2" thick architectural relief over a soil nail wall system using a 4,500 PSI mix design. The entire scope was completed in just 14 days, delivering a durable slope stabilization solution that blended naturally into the surrounding environment. 36% under traditional cast in place construction.
