    Ground Water and Liner Pools

    Please start your own thread as to not confuse OP. Split from here Casey~

    not to hijack, but how does water get under the liner and float it? I know this happens a lot as I see these threads. Being that im about to put in a partial buried AGP on a slope im now wanting to know more about this and how it can be prevented. I do know that draining a vinyl inground or buried above ground is not a good idea due to the liner moving and possible cave in on buried AGPs.

    Is that what causes liner float too? can it happen on a full pool? I wouldnt think groundwater would ever be a problem where im at with a 30 degree slope that runs away from the pool, but you never know. thanks!

    Re: Ground Water and Liner Pools

    The liner floats when the ground water level is higher than the pool water level. You can prevent this by providing enough drainage so that the ground water level never gets that high.
