The present invention is directed towards a method of forming a prefabricated block 1 having a predetermined pattern of face members, e.g. half bricks 2 moulded into a front portion 4 in one surface. The block has a rear portion 6 formed from a layer of concrete. The method comprises the steps of providing a mould 16 having side walls 18; providing a template which is laid parallel to a first mould face 20 and adjacent said side walls 18, said template defining a pattern of face member sites; loading a plurality of face members onto positions indicated by the pattern of face member sites; pouring a matrix into the mould 16, such that the matrix surrounds the face members and is retained by the side walls 18; curing the matrix such that the face members are bound into the cured matrix and are retained in the predetermined pattern to form the prefabricated block; and removing the prefabricated block from the mould 16. The matrix may be concrete. The template may be a printed fabric. A foam may be provided on the mould face before providing the template. A plastics sheet may separate the brick from the template. |
