Abstract
A double-wall structure, such as a fence wall or a parapet wall, has two back-to-back walls each constructed of successive courses of concrete wall blocks dry-stacked one atop another with each succeeding course set back relative to the immediately preceding course so that the two walls converge upwardly towards one another and are capped at the top by cap blocks. Each wall block has protuberances that protrude upwardly from the top face of the block and a groove provided in the bottom face thereof. The groove is located and dimensioned relative to the protuberances so that the grooves of wall blocks in each succeeding course engage with the protuberances of wall blocks in the immediately preceding course to establish the setback distance between abutting courses of wall blocks.
