Proto II™ Wall Systems

The idea of using post tensioning to structurally support masonry fencing in lieu of rebar and grout was unheard of in the mid 1980’s. At that time, Harold Greenberg had developed and patented a post tensioned masonry fence system called The Proto-II™ Wall.

The Proto-II™ Wall provided a superior and cost saving product when compared to traditional masonry wall systems. Royce Masonry began installing Proto-II™ Walls in Arizona in 1986. At the same time, Harold established a licensing business called Proto-II™ Wall Systems and began licensing masonry contractors outside of Arizona.

Over the past two decades, the Proto II™ Wall has set new standards for masonry fence and retaining wall construction and has become a preferred product throughout the Southwestern United States.
