Columbia Masonry Construction

The Operative Plasterers' and Cement Masons' International Association of the United States and Canada, also known as the OPCMIA, represents the members of one of the world's oldest crafts. Its members are the carriers of a tradition that predates the Pharaohs pyramids. As early as man was building shelter for himself, there was plastering, first with mud or clay and later with a lime mixture much like what is used in modern times. The name of Operative Plasterers' and Cement Masons' International Association was adopted in 1882.
