A flexible face-slab has a layer ( 11 ) of natural sandstone from which its natural binding material has at least been partially removed, but without disturbing its natural granular structure consisting of sand-grains being in contact with each other. The empty spaces, created in the layer ( 11 ) after the removal of the natural binding material are partially or completely filled with a flexible binding agent, which can be a synthetic resin-based binder. One side of the layer ( 11 ) of natural sandstone is strengthened by a base layer ( 12 ) that acts as a stabilizing layer. This may incorporate a mesh ( 13 ), woven cloth material, or threads of natural or an artificial material. The total thickness ( 17 ) of the sandstone layer ( 11 ) and the base layer ( 12 ) after completion of the manufacturing process may range between 2 and 6 mm. |
