    Vinyl Liner Wrinkles

    Wrinkles have developed over time in the shallow end of our in-ground vinyl liner pool. Does any one have any idea how to prevent these wrinkles, or how to fix them? Thanks for your help.

    Re: Vinyl Liner Wrinkles

    Wrinkles usually happen when the local water table gets higher than the pool water level. That will cause the liner to start to float up and it can sometimes shift position while floating, before going back into place (or almost into place) when the water table goes down. If that is the issue here, the only way to avoid it is to keep the water level in the pool extremely high when the water table level is high.

    There are some other possible causes, but they are all rather less likely.

    Re: Vinyl Liner Wrinkles

    Thank you for the reply. However; I'm a bit confused. I know that the water table never gets that high. We have a tile surrounding the base of the deep end of the pool that empties into pond less than 100 feet away whose top-level is several feet below the main drain. There is only a small amount of runoff during heavier wet periods like a Spring rain.
