1. A sealing device comprising:
i) a waterproofing layer having a first and a second major surface and comprising at least one thermoplastic elastomer P1 and
ii) an outer layer of non-woven fabric directly adhered over at least part of its surface to the second major surface of the waterproofing layer,
wherein the outer layer of non-woven fabric comprises at least one polymer P2,
wherein the outer layer of non-woven fabric is directly adhered over at least part of its surface to the second major surface of the waterproofing layer through thermal bonding without the use of an adhesive, and
wherein the sealing device further comprises a top layer having a first and a second major surface located on the upward facing side of the waterproofing layer opposite the side of the outer layer of non-woven fabric.
