A liner, a double-walled tank including such a liner, and a method for retrofitting or creating such a liner wherein the liner is designed to be self-supporting. Specifically, the liner is formed by adding structures to the inner surface of an existing single- walled or double walled tank which project from the inner surface of the tank into the internal volume. The combination of the surfaces of the structures and the remaining inner surfaces of the tank form a modified inner surface which then has a liner placed adjacent thereto. The liner is hardened or other fixed in form to provide for an internal liner which retains negatives of the shapes of the structures and is capable of resisting deformation should the original tank be removed and the liner be filled with material that originally would occupy the tank. |
