A method and apparatus for impregnating a liquid such as a resinous liquid into wood, in which timbers to be subjected to the impregnation are placed in a presure tank which is capable of reducing or increasing the interior pressure thereof; the inside of the pressure tank is evacuated through a monitoring timber identical in properties with the timbers to be subjected to the impregnation, to expel the air present in the tank and the timbers; the liquid is injected into the pressure tank under pressurized conditions, while continuing the evacuation, to impregnate the liquid into the timbers; and the impregnation is completed when the liquid begins to flow out of the tank through the monitoring timber.
