Assessment of Techniques for 'In Situ' Repair of Flexible Membrane Liners

摘要

The investigation indicated that there is no current technology that can be used to repair leaks and other damage in flexible membrane liners (FMLs) that are in service below wastes. Applying the basic criteria used in assessing and testing liners and seams in FMLs that are being installed, it appears highly questionable that conditions required for preparation of adequate seams and permanent repairs can be met with FMLs exposed below wastes. Liners exposed to the weather only can be repaired if the proper conditions of cleanliness and dryness are met.
