ABSTRACT:
A method and apparatus is disclosed wherein a trencher digs a trench in the ground which forms a mold for plastic concrete which, when set, comprises a concrete wall. An arm extends into the trench behind the trencher and is secured to a scoring tool; the scoring tool includes a scoring plate having a pattern formed in one edge thereof. The scoring plate is urged into a wall of the trench and forms a negative of a decorative pattern as the scoring tool is transported along the trench by the trencher. Plastic concrete is then poured into the trench; when the concrete is set, a portion of the soil is removed to expose the decorative pattern formed in the concrete.
