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 mating form liners each having a reciprocal contoured surface to that of the desired stone wall. The wall is formed from hardenable construction material such as concrete poured between two mold members with the form liners attached to at least one of the mold members. Each of the form liners has a lateral relief mold face adapted to provide a molded surface having the contour of a stone wall. Each lateral relief mold face of the form liners has a latticework non-linear mortar-forming interlocking portion surrounding stone-forming recessed portions. The form liners ar positionable in a plurality of arrangements wherein the interlocking portions and recessed portions along the mating edge of each form liner mate along the mating edge of the adjacent form liner to form a continuous lateral relief mold face.
