  • Patent number: 8905818
    Abstract: This invention relates to a process which may be automated for the manufacture of stone blocks for use as finished landscape stone blocks from quarry stone. The natural stone is quarried from the quarry and split into rectangular blocks, with squared ends and the top and bottom surfaces are ground with a plurality of grooves and ridges of varying heights. The ridges of varying heights are then removed thereby producing a surface having ridges of uniform height and grooves of uniform depth. The blocks may be used to form an architectural wall. The process is also applicable to pavers, steps and coping stones.
