Bricklayers prepare and lay brick and other masonry units to construct and repair structures such as walls, partitions, patios, arches, fireplaces and chimneys and other elements in commercial and residential buildings. They work with masonry materials such as brick, concrete block, stone, structural tile and precast panels. They also lay or install fire brick or castable materials in commercial and industrial vessels, as well as acid tile and acid brick.

Bricklayers interpret drawings and blueprints, and calculate the materials required and must know the properties of various mortars and other bonding materials, and how to handle different types of masonry units.
