Clay bricks are cast on the face of the panel.
Specialist brick manufacturers supply 230mm x 76mm x 15mm thick bricks in a range of colours. The wax coated bricks are held in position by interlocking plastic frames while the concrete is poured. The plastic frame also forms the finished joint. Various conventional brick bonds can be achieved by cutting. Following the lifting of the panel, the plastic frames are peeled from the surface. The bricks are then pressure cleaned removing the wax coating along with any concrete slurry.
