Precast panels with brick veneers offer an attractive alternative for architects and designers who don't like the look of concrete. Instead of using standard bricks, a type of brick called slab brick is used, and either cast-in or applied by a mason or tilesetter. Using the cast-in system, a liner is produced to pattern and size requirements. The brick or tiles are pressed into the pockets in the form. No special skills are needed to place the brick. No special mix design is required for the concrete, but the mix must be adequately vibrated to consolidate and fill mortar joints. The applied method of brick veneer installation requires the enlistment of trained personnel to apply the brick face to the concrete surface. Many times, masons or tilesetters are not trained in working with slab brick, and some operations may find it easier to train an already skilled worker to do the job.
