<p>Block paving is well known and can be used to create a circular paved area. Conventionally, rectangular blocks are used by arranging a first circle of blocks spread out like a fan around a centrepiece and subsequently further rows of blocks are fitted around the first row. Using this method the adjacent blocks are not parallel and there is a tapering gap between blocks which can be unsightly and difficult to fill. A method of manufacturing a set of paving blocks for use in producing a circular paved area is described, the set having at least a first course 11 and a second course 12 having a different radius from the first course, the courses being selected such that the set can be manufactured from a single mould. The method of manufacturing the set is such that the courses of the set can be assembled with a plurality of similar sets in a circular manner with the sides of adjacent blocks parallel, thereby avoiding unsightly gaps that are difficult to fill. <IMAGE></p> |
