La barrière imperméable aux fluides définit au moins une sortie. La barrière imperméable aux fluides comprend un premier panneau et un second panneau scellé sur le premier panneau le long d'un périmètre des premier et second panneaux. Une partie du périmètre comprend un joint d'étanchéité conçu pour sceller de manière amovible le périmètre des premier et second panneaux. La gaine comprend également au moins un matériau poreux disposé dans la chambre. La base est conçue pour être fixée à la région proximale de la gaine.
