Patent attributes
A first concrete block has an exposure face with a non-planar first topographical definition and a first edge along the side face and a second edge along the second side face. The first edge has a first irregular profile. A second concrete block has an exposure face with a non-planar second topographical definition and a first edge and a second edge. The second topographical definition is different from the first topographical definition. The second edge of the second block has an irregular profile that is the mirror image of the first irregular profile. The blocks can be oriented adjacent and against each other for a seamless appearance. Assembling methods include orienting the first side of the first block against the second side of the second block and aligning the first irregular profile of the first block with the first irregular profile of the second block for a seamless appearance.
