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 which can be constructed as a channel within a generally elongate mound of a naturally occurring material and thereafter permitting a top surface of the concrete mixture to assume a non-level configuration. Preferably, a joint forming material is placed on the top surface of this first concrete mixture. In like manner, a second concrete mixture is poured on top of the first layer and a joint forming material is included. Additional layers can be added, with the concrete mixtures preferably including decorative additives that are exteriorly visible. After form removal by removin…
