Abstract

The invention relates to a seal between a side face of a first part (11) and an application face (10), the seal being made of a compressible profiled lining (1) and being comprised of an internal portion (2) sealingly fixed to the first part (11) and an external portion (3) bearing on the application face (10). According to the invention, in its original condition prior to setting the seal on the first part (11), the external portion (3) of the liner (1) is provided with at least one profile tongue (4) housed inside at least one longitudinal groove (5) provided in said external portion (3) and opening on the side of the application face (10), said tongue (4) being fixed to the internal face (50) of said groove (5) in an easily detachable way so as to be able to suppress and eventually replace the tongue (4) at least on a portion of the length of the liner (1) in order to vary the compressibility degree of the liner on the corresponding length. The invention applies particularly to seals between the side faces of prefabricated concrete voussoirs for the construction of tunnels.
