The installer should examine the substrate stability and identify any areas that may require further preparation. Before a lining is installed in any structure, the installer must determine that the structure is stable and whether it is wet or dry.

To prevent excessive damage from such failures when a reservoir is placed in operation, visual inspection of the system should be made during the first fill. Thereafter, throughout the life of the reservoir, regular inspections should be performed, where possible. If failures are observed or suspected, a more detailed inspection should be conducted. If necessary, the reservoir should be taken out of service to determine whether failures exist. If failures are discovered, the causes should be determined and repairs made immediately.
