Abstract

A floor element for forming a floor covering, wherein the floor element comprises a decorative layer made of a ceramic material and a support layer arranged below the decorative layer, wherein the support layer comprises edges provided with coupling elements configured to allow a mechanical coupling with coupling elements of an adjacent floor element and wherein the floor element comprises an intermediate layer having a resin material that permeates a lower surface of the decorative layer. A method for manufacturing a floor element, comprising the steps of: (i) providing a decorative layer made of a ceramic material; (ii) providing a support layer; (iii) providing a resin material for bonding the decorative layer and the support layer together; (iv) pressing the layers together for forming the floor element such that the resin material permeates the ceramic layer.

Claims (22)

1 . A floor element for forming a floor covering, the floor element comprising:

a decorative layer comprising a brittle material;

a resin material that permeates a lower surface of the decorative layer; and

a support layer arranged below the decorative layer,

wherein the support layer is formed of a plurality of separated elements, or

wherein the support layer comprises grooves separating adjacent portions of the support layer.

2 . The floor element according to claim 1 , wherein the resin material comprises epoxy.

3 . The floor element according to claim 1 , wherein the resin material is free from fillers.

4 . The floor element according to claim 1 , wherein the resin material covers 80 percent or more of the lower surface of the decorative layer.

5 . The floor element according to claim 1 , wherein the floor element has a resin content of at least 150 g/sqm.

6 . The floor element according to claim 1 , wherein the decorative layer comprises a ceramic material.

7 . The floor element according to claim 6 , wherein the decorative layer has an apparent porosity between 0.1% and 10% measured according to ASTM C373.

8 . The floor element according to claim 6 , wherein the decorative layer has a volume of open pores comprised between 0.01 cc and 1 cc measured according to ASTM C373.

9 . The floor element according to claim 6 , wherein the decorative layer comprises a red body ceramic tile.

10 . The floor element according to claim 6 , wherein the decorative layer comprises a porcelain tile.

11 . The floor element according to claim 6 , wherein the decorative layer further comprises a glazed upper surface.

12 . The floor element according to claim 1 , wherein the support layer comprises rigid polyvinylchloride (PVC).

13 . The floor element according to claim 1 , wherein the support layer has a flexural modulus between 1.5 and 3.5 GPa.

14 . The floor element according to claim 1 , wherein the support layer has a thickness of less than 6 mm.

15 . The floor element according to claim 1 , wherein the support layer comprises one or more edges extending beyond a respective edge of the decorative layer.

16 . The floor element according to claim 1 , wherein said grooves are open toward a lower surface of the support layer.

17 . A floor covering comprising a plurality of floor elements according to claim 1 .
