ABSTRACT:
The present invention is a contoured wall and method for creating the contour and appearance of a wall formed from individual assembled units such as stones. The wall is formed from a plurality of interlocking wall portions that each have at least two non-linear mating surfaces. Each of the wall portions further has a lateral face contoured to resemble the stone wall. The wall is formed from hardenable construction material such as concrete poured between two mold members. Each of the mold members has a lateral mold face with at least one of the lateral faces having a plurality of interlocking contoured relief portions to provide a molded surface having the contour of a stone wall. In one embodiment, at least one of the mold members includes a plurality of individual form liners, or mold modules, each of which includes two non-linear mating edges and a lateral relief mold face.
