method for the manufacture of a seal for civil engineering structures and examine the sealing of the sealing

摘要

The invention relates to a seal for civil-engineering structures or the like, in the case of which a sealing layer on panel-type elements comprising corrosion-resistant metal sheets, such as stainless-steel metal sheet, is applied and adhesively bonded on a solid structural bottom layer, such as a concrete layer with a fine layer, and the joints of bordering elements are designed as expansion joints and are welded to one another right the way through, in the case of which tubular checking lines are laid in the expansion joints in order, after the seal is finished, to be able to establish, with the aid of a noble gas introduced into the checking lines and by scanning the seal and welded joints, any leakage by the detection of escaping noble gas.
