Since its founding in 1865, the International Union of Bricklayers and Allied Craftworkers has actively fought to improve our members’ quality of life – on and off the job – through access to fair wages, good benefits, safe working conditions, and solidarity among members.
Today, we represent the most highly skilled trowel trades craftworkers across the United States and Canada including bricklayers, stone and marble masons, cement masons, plasterers, tilesetters, terrazzo and mosaic workers, and pointers/ cleaners/ caulkers. With over a century of protecting the rights of our workers, BAC is the oldest continuous union in North America.
BAC membership is represented by Locals and Administrative District Councils (ADCs) in five regions – Northeast, North Central, South, West, and Canada.
The International Masonry Institute (IMI) is a labor-management cooperative of BAC and the contractors who employ its members.
BAC became an international union in 1881 with the admittance of locals representing workers from Hamilton and Toronto in Ontario, Canada.
Since 1986, BAC Craft Awards have saluted Local Unions and workers for excellence in the trowel trades and distinguished service to their Local Unions and communities.
