Abstract: A tank lining system comprises a tank having a wall defining a first opening. A flexible sheet lining abuts the interior surface of the wall and defines a second opening that is aligned with the first opening of the tank wall. A first collar surrounds the first opening and is attached to the tank, while a second collar surrounds the second opening and is attached to the flexible sheet. Means are provided for retaining the first and second collars together with a seal of the junction area between them. The tank is sealed by removing air from between the lining and the tank prior to inserting the seal between the collars.
