ABSTRACT:
It has various layers in its structure: the lower layer (2, 2′, 2″) is a resistant base of ceramic origin or similar; the upper layer is a lamina (1) with a visible surface. The two are stuck by an adhesive defining a homogenous intermediate layer (3) without the formation of fragile zones due to the absence of air bubbles since the contact face of the ceramic base (2, 2′, 2″) is domed, the central point being higher than the rest. For preventing the surplus adhesive from flowing out and becoming stuck to other adjacent tiles, it has been provided for the ceramic base or similar (2, 2′, 2″) to include a perimetric flange (5, 5′) which will then be eliminated during the phase of machining the edges when formatting the tile. The perimetric flange (5, 5′) advantageously incorporates some lateral projections or centering stops (6) of the facing lamina (1) in order to optimise the pressing.
