Bricklayers lay bricks, concrete blocks, stone and other similar materials to construct or repair walls, arches, chimneys, fireplaces and other structures in accordance with blueprints and specifications. They are employed by construction companies and bricklaying contractors or they may be self-employed.
Refractory masons protect structures from high heat by installing special refractory bricks, castables, blankets, plastics, or ceramic coatings to furnaces and kilns. They must be skilled at laying refractory bricks, installing castables, and removing old refractory masonry. This is a specialty trade for those who are certified as brick and stone masons.
