发明名称 IMPROVEMENTS IN AND RELATING TO SURFACING BLOCKS
摘要 A surfacing block (1) has upper and lower surfaces (2, 7) bounded by walls (5) extending between the surfaces (2, 7). The surfaces (2, 7) are of a generally cruciform shape having four arms (4) each of which extend in a direction substantially parallel to the lower surface (7) and substantially perpendicular to two of the other arms (4) of the block. The block (1) has around the boundary of its surface projections (8) and/or recesses (9) for interlocking engagement with recesses and/or projections of a neighbouring block. The shape of the block helps to improve the resistance to movement of the block when laid with similar blocks.
