    Abstract: A method is disclosed for producing a tubbing made of concrete for lining a tunnel, particularly a traffic tunnel, wherein the tubbing has a convexly curved outer surface and a concavely curved inner surface opposite the outer surface. The method can include: a) placing a membrane having a dispersion adhesive layer and a thermoplastic sealing layer onto the outer surface and further onto at least one of the sides of the outer side surfaces of the tubbing facing the outer surface, wherein the dispersion adhesive layer faces the tubbing; b) supplying heat, thus partially melting the dispersion adhesive layer; and c) cooling the dispersion adhesive layer, thus forming an adhesive bond between membrane and the tubbing.

    Abstract: An activator composition having a) between 0.5% and 50% by weight of a catalyst K for crosslinking two-component adhesives which is liquid at 23° C., b) between 40% and 99.5% by weight of an organic solvent L, c) between 0% and 10% by weight of at least one silane S including at least one hydrolyzable silane group and preferably at least one functional group selected from mercapto, epoxy, amino, methacryloyl, vinyl and alkyl group. The activator composition is storage stable for at least one month. The activator composition is moreover active independently of the applied amount and may be applied in layers having a thickness such that the adhesive may be applied after not more than 30 seconds.
