ABSTRACT:
A method of making a concrete block having decorative stones embedded in a surface thereof includes the steps of placing on a face plate a layer of stones which includes a plurality of spaced decorative surface stones and includes filler stones substantially smaller than the surface stones and disposed in the spaces between the surface stones, applying a cement mortar on the surface stones and filler stones, introducing concrete into a separate mold, inverting the face plate and placing it on top of the concrete in the mold, consolidating the concrete and assembling the concrete and the sruface stones by applying pressure and vibration, removing the mold and the face plate, and curing the resulting block without the mold.
