<p>There is a described a moulded concrete paving slab having a face which is cruciform in shape, and comprises a central region (ABCD) and four rectangular lateral extensions (LAKD, EFAB, BGCH, DCIJ) each of which is bounded on one side by a respective side of the central square region, and a pattern of paviours (5, 6) delineated on the face, wherein at least one of said paviours extends across at least one of the boundaries of the central region. The central region may be square, or may be a rectangle with a pair of longer sides and a pair of shorter sides. The pattern of paviours is irregular. In one embodiment, each lateral extension extends along the full length of a respective side of the central region of the cruciform face. Each lateral extension may be substantially of the same size and shape as the central region. Alternatively, each lateral extension may extend along substantially half of the length of a respective side of the central square region of the cruciform face. The pattern of paviours may extend to the edges of the cruciform face, with the paviours separated by pointing gaps (4) formed by channels, and the slab may further have spacing nibs (9) on its respective edges, wherein the nibs are of a height substantially the same as the width of said pointing gaps.</p> |
