Claim:
A system for building a masonry wall on a building surface, the system comprising: a plurality of artificial masonry units, each one of said masonry units having a front face, a back face, and two pairs of parallel lateral faces having a thickness (t m ), wherein the front face and the back face each have a height (h m ) and a length (l m ); at least one panel having a front face provided with a plurality of horizontally extending channels delimited by protruding ribs for receiving rows of said masonry units in the channels, said ribs having a predetermined thickness (t r ) smaller than said thickness (t m ) of the masonry units, wherein each of said channels has a height (h c ) delimited by an upper rib and a lower rib of the protruding ribs; rib guiding means positioned along one of the upper rib and the lower rib of each of said channels and facing toward each of said channels and unit guiding means positioned along one of the lateral faces of the masonry units so that the single masonry unit lateral face comprising the unit guiding means is engaged by the rib guiding means and the remaining faces of the masonry unit are not engaged by the rib guiding means, said rib and said unit guiding means being interdependently positioned for guiding the installation of the masonry units in the channels so that horizontally-arranged masonry units are equally spaced-apart from each other by a predetermined gap (g); wherein at least a first one of said masonry units is positionable in the panel in: (i) a horizontal orientation, wherein the length (l m ) is greater than the height (h m ), and (ii) a vertical orientation, wherein the height (h m ) is greater than the length (l m ) and is greater than the height (h c ) of one of the channels.
