ABSTRACT Pieces of marble or similar natural stone having a plurality of plane faces are stacked in a liquid-tight container. Said pieces are arranged with their plane faces facing each other so as to form a plurality of parallel layers. Thereafter, a vacuum is applied in said container and, while maintaining the latter under vacuum, a fluid hardenable binding composition, such as a synthetic resin, is then poured into said container. Said composition flows down through the interstices existing in and around the stack of pieces, until it completely covers said stack. Thereafter, the inside of the container is brought to atmospheric or superatmospheric pressure, thus causing said binding composition to thoroughly penetrate into all said interstices and into all the cavities of the pieces opening on their surface, and then said binding composition is allowed to harden.
