Hard surface-veneer engineered surfacing tiles
A modular tile assembly having a substantially rigid substrate, at least one sealant layer, and at least one stone, ceramic, or porcelain tile. A bottom surface of a first sealant layer being bonded to an upper surface of the substrate and a top surface of a second sealant layer being bonded to a lower surface of the substrate. The tile being bonded to at least a portion of the top surface of the first sealant layer. In one example, the substrate is provided with a tongue or a groove defined in any one, combination, or each of the respective side edges of the substrate, as desired.
1. A flooring tile, comprising:
a generally planar monolithic substructure sheet having a thickness of between 4 and 10 mm and defining an upper and lower surface of a select geometric configuration, said sheet defining at least a first and a second edges where the first edge features a profiled tongue structure projecting therefrom in a plane generally parallel to the upper surface and said second edge including a groove recess corresponding in shape and dimension to the profiled tongue of the first edge, where inserting said tongue structure of said first edge into the groove structure of said second edge interconnects abutting engineered tiles;
a sealant layer having a top surface and an opposed bottom surface, the bottom surface of the sealant layer being bonded to the upper surface of the planar substructure sheet; and
a veneer layer bonded to the top surface of the sealant layer, said veneer layer being composed of a material selected from the group consisting of sliceable natural stone, marble, granite, slate, glass, and ceramics, where said veneer has a thickness of 3-10 mm and possesses a Mohs hardness of at least 3.
2. A flooring tile according to claim 1 , wherein the veneer layer is recessed from the edges of the substructure sheet and comprises a plurality of discrete segments disposed on the substructure sheet so as to provide uniformly spaced gaps having a depth corresponding to at least the thickness of the veneer layer and having a pre-selected width between adjacent segments for receiving and retaining grout.
3. A flooring tile according to claim 1 , wherein the veneer layer has a breaking modulus greater than 30 N/mm 2 .
4. The flooring the according to claim 2 , wherein the tongue and groove profile force interlocked abutting panels towards each other in compression for glueless installation.
5. An engineered tile, comprising:
a generally planar monolithic base of selected dimensions and configuration, said base including an upper surface, a lower surface, a first edge incorporating a first cooperating element of an interlocking member, and a second edge incorporating a second cooperating element of said interlocking member;
a sealant layer having a top surface and an opposed bottom surface, the bottom surface of the sealant layer being bonded to the upper surface of the planar base; and
a veneer layer having a Mohs hardness of greater than 3 and a thickness of between 2 and 8 mm affixed to said top surface of said sealant layer, said veneer layer being dimensioned so as not to overlie said first cooperating member.
6. The engineered tile according to claim 5 , wherein the veneer layer is composed of a material selected from the group consisting of sliceable natural stone, marble, granite, slate, glass, and ceramics.
7. The engineered tile according to claim 6 , wherein the veneer layer is a ceramic of a type selected from the group consisting of Monocuttura ceramic, Monoporosa ceramic, porcelain ceramic, or multi-casted ceramic.
8. The engineered tile according to claim 5 , wherein the veneer layer has a breaking modulus greater than 10 N/mm 2 .
9. The engineered tile according to claim 8 , wherein the veneer layer has a breaking modulus greater than 30 N/mm 2 .
10. The engineered tile according to claim 6 , where the veneer layer is sliced and polished natural marble of a thickness of between 4 and 6 mm.
