Abstract: The invention relates to a sealing element (1) comprising: i. A waterproofing adhesive layer (2) having first and second major surfaces, ii. An adhesive layer (3) covering at least a portion of the first major surface of the waterproofing adhesive layer (2), and iii. A carrier layer (4) on the side of the waterproofing adhesive layer (2) opposite to the side of the adhesive layer (3), wherein the waterproofing adhesive layer (2) is composed of a self-adhering bituminous composition and the adhesive layer (3) is composed of a non- bituminous pressure sensitive adhesive. The invention also relates to use of the sealing element as a waterproofing, roofing, vapor barrier, vapor retarder, or a façade membrane, or as a waterproofing, roofing tape, or façade tape.

Abstract: The invention is directed to a sealing element (1) for sealing joints in concrete structures comprising a profile (2) having a center portion (3) and first and second side portions (4, 5) on opposite sides of, the center portion (3). The side portions (4, 5) of the profile are at least partially covered with a functional coating (6) which is operative to bond with a fresh cementitious composition casted against it and allowed to harden. The invention is also directed to a method for producing a sealing element, to a method for sealing a joint between two sections of concrete, to a sealed construction, and to use of a sealing element for sealing of a joint in a concrete construction.
