Abstract
A constructed wall structure and method of fabrication that replicates a wall formed by nature. The structure has a plurality of discrete layers, with each layer constructed of concrete and a decorative additive. Every layer has an interface with an adjacent layer to thereby form a plurality of interfaces wherein at least one, and preferably most or all, of the interfaces are non-level. Non-limiting examples of decorative additives are rocks, sea shells, colorants, and mixtures thereof. Methodology for fabricating the wall structure includes pouring a first concrete mixture into a substantially vertical form and permitting a top surface to assume a non-level configuration. Preferably, a joint forming material is placed on the top surface of this first concrete mixture to thereby form a first layer of the wall. In like manner, a second concrete mixture is poured on top of the first layer and a joint forming material is included. One or more additional layers as desired can be added in the same way to thereby complete physical formation of the wall, with the concrete mixtures preferably including decorative additives that are exteriorly visible. After form removal, the entire wall or…
