If they are the same type feed sacks my chicken feed comes in they should be OK for what you are wanting to do. Mine do seem more water tight than the previous type my feed company was using (they recently changed bag types as well). You could test them by pouring water in one of them and see how it filters out just to be sure. Might take longer for your dirt to cure and dry out, but it still should dry.
