Two forms of paving block are disclosed each having a hexagonal body portion capable of being divided along a central score line into two mirror image portions and one of the forms of block further containing a square stem portion also separable from its associated body portion along a further score line. A ground covering structure is formed by laying the blocks laterally side by side to form a substantially continuous paving employing both forms of blocks and selectively breaking the hexagonal portion of such blocks and fitting the severed mirror image portions into voids whereby the perimeter of the structure can be defined by straight lines without further breaking or cutting of any of the block forms.
