To make room for new Hoag Hospital buildings, a large slope was cut vertical and shored — and Boulderscape sculpted 35,350 square feet of structural and architectural shotcrete into a Newport Sandstone finish the hospital chose for its natural look, delivered in 9 days at 30% below traditional construction.

Several new Hoag Hospital buildings were planned at the base of a large hillside, requiring the slope to be cut back to near vertical and stabilized with a soil nail wall system. Because the retaining wall would remain highly visible to patients, visitors, and staff, Hoag placed a strong emphasis on aesthetics and selected Boulderscape's Newport Sandstone finish to help integrate the structure into the surrounding environment.
Boulderscape hand sculpted 35,350 square feet of fractured sandstone texture designed to replicate the natural character of Southern California rock formations. As part of the project, the team also furnished and installed 1,087 linear feet of V ditch drainage behind the wall to support long term site performance.
The project consisted of an 11" thick structural shotcrete section with an average 3" thick architectural relief over a soil nail wall system using a 4,500 PSI mix design. The entire scope was completed in just 9 days, delivering a durable retaining wall solution that combined slope stabilization, drainage, and architectural finishes into a single integrated system.
