        Purbeck
        makes a great external paving. It reflects light onto
        surrounding buildings and makes their appearance lighter
        and brighter.  It
        is available in a mix of several widths x random lengths.
        For pedestrian use it can be laid at 40mm thick, and for
        vehicular traffic 75mm minimum.  
        It is generally laid to
        courses, across the narrowest width as shown. It can also
        be made into setts, kerb and channel.
