Abstract: A concrete paving stone having single flags held together with a number of concrete ribs between adjacent stones such that the ribs will resist breaking during ordinary handling but will break upon the application of vibration after the paving stone is laid on a level sand bed to thereby provide a number of unconnected flags.

Abstract: An earth retaining wall formed by stacked, alternately staggered rows of spaced, nesting, chevron-shaped concrete blocks. Adjacent blocks in some rows are coupled together by connecting tubes extending into holes through the blocks, and elongated anchoring devices are connected to the tubes and extend horizontally into the earth. Alternatively, the anchoring devices may be concrete extensions integrally moulded with the blocks.
