Abstract
A unitary paving block having an exposed surface in use having a multitude of markings to simulate individual, random paving elements has a periphery with a shape which enables the block to be laid with other similar blocks in an irregular, substantially unrepeated paving array. The shape of the periphery of the blocks is such that the blocks can be laid with each block angularly moved with respect to each other and/or laid in staggered relationship with respect to each other.
