can liquefaction be used to sink a "popped" in-ground pool

[Coruptor]

The pool is in South beach Florida which has a high water table and sand. The city drained the pool while my boss was away and did not pull the drain plugs. The preferred method is to mudjack, but I was wondering if large cement vibratory compactor and partially filling the pool, would do anything to help lower the high end which rose over 18 inches. Any help or suggestions would be greatly appreciated.
Thank you,
Jerry

I can't imagine a method that would allow the pool to be sunk back into ground that doesn't involve removing the pool completely fist.

It is highly doubtful that you could induce enough vibration to cause liquifaction over a large enough area to do as you are thinking. Besides, you are likely only a few feet above rock and you will have limited effect. Further, if you could induce the right magnitude and frequency of vibration, you'd probably damage adjacent structures.....bottom line....ain't gonna work. Start over.

With liquifaction... I would think the pool would pop up more... like quicksand... many people don't realise that to 'escape it', you simply have to lay back and relax... you should float.

Short of removing and replacing, have you considered the alternate of elevating the lower end (Tower of Pisa sort of thing!).

Is this pool shallow at one end and deep at the other?

Unless I'm missing something here with long term inground pool performance, before you so any repairs, I would try to figure out why the uplift/settlement occurred and fix the problem.

Mike,
He knows what happened. Look at his OP. The pool became a boat and floated.

You could try to cut a transverse slit on the bottom of the pool on the high end and inject water to liquify the sand and use a mud sucker to remove the saturated sand. Do it slowly and see what happens before other drastic measures.
