A decorative concrete with a very uniform finish surface and a method of fabricating the same is disclosed. A concrete mixture is poured over a subgrade which defines an exposed surface. The exposed surface is finished with any of several techniques, and the surface is then worked with an abrasive material, and additional techniques are used to color and seal the concrete.

A process (method, system, etc.) for the manufacturing of slabs made of resin-bonded mineral grits comprises at least the phases of: supply of at least one mixture made of mineral grits and resins; compaction of the mineral grits and resins to obtain a compacted slab; hardening of the compacted slab to obtain a finished slab provided with at least one exposed surface and having an intrinsic degree of porosity; decoration with ink by digital printing of the exposed surface according to at least one predefined design; and, prior to the decoration and subsequently to the hardening, at least one phase of increase in the intrinsic degree of porosity of the finished slab, adapted to promote the penetration of the ink in the finished slab.
