Tile and Thin Brick Veneers Glazed ceramic tile veneers and thin bricks—hard-faced tile-like sections of brick—have specially molded backs that lock into wet concrete. They are cast into concrete backers using formliners to hold them in place while the panel is cast on top of them. Formliners can provide either a crisp, machine-laid, or a more irregular, hand-laid appearance. A variety of joint details and an ever-expanding variety of brick sizes, colors, and textures are available. Tiles and thin bricks can either cover precast panels completely or be designed to work with exposed concrete areas. Thin brick is highly impervious compared to full- or half-bricks due to its molding process. Because an impervious precast panel backer replaces traditional pervious “mortar” joints, water will not get behind a thin-brick veneered panel and cause bricks to pop off.
Stone Veneers and Matching Finishes Granite, limestone, and marble veneers (e.g., 1-1/2"–2" thick) can be drilled, fitted with stainless steel pins, and cast into rigid precast backers to provide large, fully or partially veneered panels. Stone-veneered precast panels can be an efficient way to clad high-rise buildings. For economy, natural stone veneers are often used on lower levels of buildings with matching custom-mixed all-precast panels on the upper levels. These veneers also eliminate the fireproofing required to protect steel-framed curtainwall assemblies. To ensure best quality, and to speed installation, sealing between stone joints can be done in the factory, leaving only the sealing between panels to be completed in the field.
