Abstract

Procedure for checking the tightness of a wall having an internal face and an external face, characterized in that it is implemented by means of a device that forms a suction cup, movable when in operation, said device comprising a body that includes at least one support surface intended to be applied on a support; at least one control chamber having an opening located in the same plane as said support surface, and equipped with connecting means, on the one hand, with a pumping system capable of causing a depression inside said chamber, causing a force of application of said body on said support, and on the other hand, with a detection system capable of detecting the presence within the said chamber of a gas of a certain nature; support means that provide a supporting force that opposes said application force, said external face performing the function of said support, and said internal face being in contact with said gas of a certain nature, called "tracer" gas.
