Mo-Sai
Encyclopedia
Mo-Sai is a method of producing precast concrete
cladding
panels. It was patent
ed by John Joseph Earley
in 1940. The Mo-Sai institute later refined Earley's method and became the leader in exposed aggregate concrete
. The Mo-Sai Institute, an organization of precast concrete
manufacturers, adhered to the Mo-Sai method of producing the exposed aggregate precast concrete panels.
A pivotal development in this technique occurred in 1938, when the administration buildings at the David Taylor Model Basin
were built with panels used as permanent forms for cast-in-place walls. This was the first use of the Mo-Sai manufacturing technique produced in collaboration with the Dextrone Company of New Haven, Connecticut
. Working from this background, the Dextone Company refined and obtained patents and copyrights in 1940 for the methods under which the Mo-Sai Associates, later known as Mo-Sai Institute Inc. The Mo-Sai Institute grew to include a number of licensed manufacturing firms throughout the United States.
Buildings featuring Mo-Sai panels include the Columbine Building in Colorado Springs (1960), Prudential Building in Toronto, Canada (1960), Court House Square in Denver, Colorado
(1960), Los Angeles Temple (1956), Equitable Center in Portland, Oregon
(1964), and the PanAm Building
in New York City
(1962).
