Abstract

A process for impregnating at least one porous part with an impregnant comprises immersing the porous part(s) in impregnant, measuring at least one parameter indicative of the buoyancy of the porous part(s) as the impregnant impregnates same or of the effective volume of the impregnant, and interrupting impregnation when the measured parameter(s) indicates a predetermined level of impregnation is achieved. An apparatus for impregnating porous parts comprises a vessel for holding the porous part(s) and an impregnant, and a measuring device for measuring at least one parameter indicative of the buoyancy of the porous part(s) immersed in the impregnant within the vessel or of the effective volume of the impregnant.
