In smaller metal tanks any of the materials are acceptable. Hypalon will be recommended for the larger tanks or if any of the following conditions exist: * If the tank has an open top and the liner is exposed to ultravioletet light; * If the size of the tank dictates that the liner be made and installed in more than one panel; * If the metal is pitted; * If there are permanent, non-moveable support posts; * If there are any unusual penetrations throught the floor or wall. Metal tanks need to be cleaned then coated with a rust inhibitor. We highly recommend that a geo-textile underlayment be used between the tank and the liner to help insulate the liner from heat and cold transmission through the metal and to protect the liner from any chemical migration from the rust inhibitor. When installation has been completed, seal the exposed geo-textile at the top of the tank with a bead of silicone around the entire circumference. Weep holes should be drilled in the bottom of the metal tanks to allow for release of condensation.
