The primary work of cement mason is finishing the exposed concrete surfaces on many types of construction projects. These projects range from small jobs, such as finishing patios, floors and sidewalks, to work on huge dams, miles of concrete highways, foundations, walls of large buildings and airport runways. The cement mason levels, smoothes, and shapes surfaces of freshly poured concrete. Although they are involved in home building and basement and driveway work, the bulk of their work is commercial and industrial building. They also set forms for sidewalks and waterproof concrete walls.
