Mo-Sai
From Wikipedia, the free encyclopedia
Mo-Sai is a method of producing precast concrete cladding panels. It was patented by John Earley in 1940. The Mo-Sai institute later refined Earley's method and became the leader in exposed aggregate concrete.
Buildings featuring Mo-Sai panels include: Columbine Building in Colorado Springs (1960); Prudential Building in Toronto, Canada (1960); Court House Square, Denver, Colorado (1960); Los Angeles Temple (1956).
The Mo-Sai institute, a national (USA) organization of precast concrete manufacturers, adhered to the Mo-Sai method of producing the exposed aggregate precast concrete panels.
