At Peak 8 in Breckenridge, Boulderscape cleared the way for a new chalet — hand-finishing 22,000 square feet of structural shotcrete to a clean Class A steel trowel face, delivered 32% faster than cast-in-place at 36% below traditional construction.

A new chalet development at Peak 8 in Breckenridge required large soldier pile retaining walls to support the site before building construction could begin. The owner wanted a clean architectural appearance with smooth gray walls while placing a high priority on accelerating the construction schedule so work on the chalet could proceed as quickly as possible.
Boulderscape constructed the retaining walls using structural shotcrete and hand finished every surface to a smooth Class A Steel Trowel finish. The shotcrete method provided a clean, uniform appearance while allowing the retaining walls to be completed significantly faster than conventional cast in place construction.
The project encompassed 22,340 square feet of wall surface consisting of a 12" thick structural shotcrete section with an average 1/8" thick architectural relief over a soldier pile wall system using a 5,000 PSI mix design. The entire scope was completed in just 11 days, delivering a durable retaining wall solution with a high quality architectural finish. 36% under traditional cast in place construction.

8%-10% air was needed to help reduce chances of cracking in winter. Hot water and accelerators were used to help hydration of the shotcrete.
