A method of making a corrugating linerboard includes supplying a web of coated linerboard having a first side, a second side and a thickness defined by a distance between the first side and the second side, the first side being coated with a moisture-repellant material; and impregnating the coated linerboard with a hydrophobic material from the second side such that the hydrophobic material penetrates into the thickness of the coated linerboard.
