Patent number: 9650549Abstract: The present invention relates to a sealing device (1) comprising a barrier layer (2) and an adhesive layer (3), and which is suitable for sealing bases in the building sector. The adhesive layer comprises a polymer P2, the polymer P2 being polyethylene (PE), polypropylene (PP) or a copolymer of ethylene and propylene, and a polyolefin-based polymer P3, the polymer P3 having at least one functional group which is selected from the group consisting of carboxylic acids, OH-groups, anhydrides, acetates and glycidyl methacrylate, and azo-dicarbonamide A. The invention further relates to a method for sealing the said bases. The method according to the invention allows structures of civil engineering to be sealed rapidly and efficiently and ensures good adhesion of the sealing device on the base.Type: GrantFiled: May 6, 2013Date of Patent: May 16, 2017Assignee: SIKA TECHNOLOGY AGInventors: Herbert Ackermann, Matthias Gössi, Frank Hoefflin, Stefan Keiser, Roman Rohrer, Jean-Claude Rudolf
