A disadvantage of the crushed stone or gravel ringwall is that it is more difficult to construct it to close tolerances and achieve a flat, level plane for construction of the tank shell. For crushed stone or gravel ringwalls, careful selection of design details is necessary to ensure satisfactory performance.
