Abstract
A method of fabricating a formed wall structure having a plurality of discrete layers. The method includes pouring a first layer of a first concrete mixture into a first vertical form whose depth is equal to that of the first layer; pouring a second layer of a second such mixture on top of the first layer and into a second vertical form whose depth is equal to the depth of the second layer and where at least one of the walls of the second form is not in alignment with an adjacent vertical wall of the first form; and pouring at least one additional layer into a respective at least one additional vertical form situated on top of a next lower vertical form and having a vertical depth equal to the at least one additional layer and where at least one of the interior walls is not in alignment with at least a portion of a vertically adjacent interior wall of the next lower vertical form. The concrete mixtures are permitted to cure sufficiently to retain their respective shapes, and thereafter the forms are removed. This methodology accomplishes replication of naturally occurring walls whose several face layers are not situated in total alignment with each other to thereby achieve enhanced…
