Pool Bottom Bumpy

I just recently had 24ft above ground pool installed. They used a sand base (masonry sand). The top of the pool appears to be very true, but the bottom of the pool has a lot of dimples in it along with some high and low spots (not more than an inch of variance) that I can see while underwater. Is this normal? Is there any way to smooth it out now?

I've smoothed out a couple spots by hitting them with my hand while underwater. I've never owned an above ground pool and I'm just trying to make sure this isn't going to get worse or create a potential problem. Thank you.




Hi. I would say you are probably just fine. Smoothing the sand base before installing the liner is a fine art. Not everyone is going to get it perfect. I use a large push broom on the sand until it is as smooth as possible. I then install the liner from the outside of the pool. The bottoms on the pools I install are quite smooth, but again, this is an art.





The first time you change the liner, you will smooth the sand again, and it usually turns out much better the second time.
