Abstract
A covering element includes a carrier plate having a mineral material, the carrier plate formed as a flat mineral carrier plate with a content of cement larger than 35 percent by volume and with a content of natural fibers of 1 to 40% by volume. The carrier plate has a thickness between 3 and 15 mm and carries a polymer-containing decor layer on a front side of the carrier plate. Complementary recesses and protrusions are provided on opposing lateral edges of the carrier plate of the covering element, such that in an assembled condition of two or more covering elements the complementary recesses and protrusions engage with each other, wherein a portion of a polymer contained in the polymer containing decor layer penetrates into the carrier plate.
Claims17
A covering element comprising:
- a carrier plate comprising a mineral material, wherein the carrier plate is formed as a flat mineral carrier plate with a content of cement larger than 35% by volume, a content of natural fibers of 1 to 40% by volume, and a thickness between 3 and 15 millimeters (mm);
- complementary recesses and protrusions formed, respectively, on opposing lateral edges of the carrier plate, such that, in an assembled condition of two or more covering elements, the complementary recesses and protrusions are configured to engage with complementary protrusions and recesses, respectively, of another of the two or more covering elements;
- and
- a decor layer that comprises a polymer and is provided on a front side of the carrier plate, such that a portion of the polymer of the decor layer penetrates into the carrier plate.

- a decor layer that comprises a polymer and is provided on a front side of the carrier plate, such that a portion of the polymer of the decor layer penetrates into the carrier plate;
- and
- a transparent polymer-containing layer provided over the decor layer, wherein the transparent polymer-containing layer is textured and comprises corundum particles;
- wherein the decor layer comprises a printed paper;
- and
- wherein the natural fibers of the carrier plate are cellulose fibers.
