Abstract

A floor element for forming a floor covering, the floor element comprising a decorative layer comprising a brittle material, and a resin material that permeates a lower surface of the decorative layer.

Claims (20)

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 covers 80 percent or more of the lower surface of the decorative layer; and

a support layer arranged below the decorative layer, the support layer having a flexural modulus between 1.5 and 3.5 GPa,

wherein the resin content of the floor element is at least 150 g/sqm.

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 decorative layer is made of a ceramic material.

5. The floor element according to claim 4 , wherein the decorative layer has an apparent porosity comprised between 0.1% and 10% measured according to ASTM C373.

6. The floor element according to claim 4 , wherein the decorative layer has a volume of open pores comprised between 0.01 cc and 1 cc measured according to ASTM C373.

7. The floor element according to claim 4 , wherein the decorative layer comprises a red body ceramic tile.

8. The floor element according to claim 4 , wherein the decorative layer comprises a porcelain tile.

9. The floor element according to claim 4 , wherein the decorative layer comprises a glazed upper surface.

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

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

12. The floor element according to claim 1 , wherein the support layer comprises edges provided with coupling elements configured to realize a mechanical coupling with coupling elements of an adjacent floor element.

13. The floor element according to claim 12 , wherein the coupling elements are configured such that the mechanical coupling results in a locking between the coupling edges in a vertical and/or one or more horizontal directions.

14. The floor element according to claim 12 , wherein, the coupling elements are coupled with play in the coupled condition.

15. The floor element according to claim 13 , wherein the play is such that the coupling elements are coupled to each other without being deformed.

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