Dimples in Liner Bottom (AG) Yikes!

[bsbrega]

Hi I uncovered my pool today and for the first time in 15 years, I see the entire bottom covered in dimples about the size of almonds. Could this be from bugs? The pool did not leak (except the normal water reduction in winter), so I don't think the bugs or whatever is causing the dimples have eaten through. Yet. Does anyone know what these dimples are? The pool is 27' round and there must have been at least a thousand dimples. They're everywhere.

Could also be that frost pushed up some gravel through the sand....
You haven't had a chance to get in and ispect closely have you?

I WISH I had almond-sized dimples in my pool's bottom! That would be an improvement...I have footprint sized AND SHAPED dimples from the incompents who installed the liner. I don't want the liner to fail, but when it does I will be SO glad to get the bottom fixed!

Thanks, Matt. And you are correct, I haven't set foot in the pool yet. It's wierd because the little lumps appear to be fairly uniform. . .

Whatever they were, they are gone now that the pool is uncovered. Musta been frost heaves that melted in the sun. . .Maybe?

That's just plain weird - you got aliens living under the liner....could it have been shadows playing tricks.....
