The work of the modern Bricklayer touches almost all aspects of building—industrial and commercial building, apartments and homes. A Bricklayer constructs walls, partitions, fireplaces, chimneys and other structural forms from brick or other masonry materials such as firebrick, concrete, cinder or gypsum block, structural tile, terracotta, ceramic tile, terrazzo, and stone. They work with any materials put together with mortar using the trowel, chisel, jointer, brick hammer for cutting bricks and power brick cutting saws. They understand and work from blueprints. They also use measuring, leveling and aligning tools to check their work.
