Abstract: A sealing element includes a waterproofing layer having a first and a second major surface and including at least one powdered superabsorber polymer, and optionally a reinforcement layer fully embedded into the waterproofing layer or adhered to one of the major surfaces of the waterproofing layer, wherein the waterproofing layer is a polymeric layer including at least one polymer or a bitumen layer including bitumen. A building structure includes a roof or wall substrate, an insulation board, and a sealing element arranged between the roof or wall substrate and the insulation board, and the sealing element is used as a roof or wall breather membrane.

Abstract: A self-adhering roofing membrane, a fully-adhered roof system and a method for producing a self-adhering roofing membrane, the roofing membrane including a waterproofing layer including at least one polymer P1, a first adhesive layer, a barrier layer including a polymeric film including at least one polymer P2, a second adhesive layer, and optionally a release liner, wherein the first and second adhesive layers are pressure sensitive adhesive layers.

Abstract: A sealing device including a first polymeric layer, a second polymeric layer, and a third polymeric layer, the second polymeric layer located between the first and third polymeric layers and including at least one polymer and at least one powdered superabsorber polymer. Also, a method for producing a sealing device and a method for covering a substrate using the sealing devices.
