Abstract

The present invention relates to a sealing device () which comprises a barrier layer () with a thermoplastic polymer P1, and an adhesive layer () with at least one ethylene-vinyl acetate copolymer (EVA) P2 and azo-dicarbonamide A, and which is suitable for sealing bases in the building sector. The invention further relates to a method for sealing 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.
