<p>A building material i.e. damp proof course 100, 200 for incorporation into a structure including a plurality of bricks (B figure 1C) which comprise a hole or recess in or between the bricks, preferably with bricks which have three holes. The building material may comprise a main body 110 which forms a retaining region, and hollow protruding regions 120 which preferably enter the holes in the bricks. The hollow region is arranged to receive mortar (M figure 1C) to key with one or more further bricks in the structure to thereby form a stronger bond between the layers of bricks. The building material may also be a cavity tray, flashing or a lintel. Later embodiments relate to a structure, and a method of building a structure.</p> |
