Johnston [SMTP:vajohnston at nas.com] <...The other reason that I am willing to bet it will be fine is the = synergy created by the use of cement mortar to line the inside of the = tank. Not only do I get a decent liner to keep my water in, I get = increased tensile strength. Anyway, that is what I decided to line the = Cob tank with - about a half inch or so of cement mortar, either hung on = chicken >wire or metal lath.=20 You may be aware of this already, but it is the metal reinforcing that = provides tensile strength, not the cement/mortar (concrete has high = compressive strength, very low tensile strength). I'd recommend nice = heavy chicken wire or even light concrete reinforcing mesh to be sure of = plenty of tensile strength - one piece with only one (vertical) = seam/joint would be strongest. By the way, how big is this cistern = volume-of-water-wise?
