ABSTRACT:
A paving stone for use with other similarly configured paving stones all of which are to be laid adjacent each other to form a paved surface. The paving stone having two centrally symmetrical contiguous parts at least one of which is generally square-shaped and has cut-off corners. The parts being joined along a side that is common to the two parts. There being, along the common side, a dummy groove that is common to the two parts and gives the appearance of separateness between the two parts. The one part also has at each of the four cut-off corners of the square, a protrusion which extends along the continuation of a line which joins the corner with the diametrically opposite corner. Each protrusion being directed toward a protrusion of an adjacent paving stone when the paving stone is part of a paved surface formed by a plurality of paving stones. The length of each protrusion being such that there is left, between the end of the protrusion and the end of the protrusion toward which it is directed, a substantial free space through which water may flow downwardly from the paved surface.
