Sand Settling Under Pool
Sand Settles Around Brace Channel
We had a New 15 x 30 AGP installed spring 2013 and also noticed shortly after outlines of the base plates showing through the liner (like Title: Soft Sand Under Pool, post).We purchased an installer installed Armor Shield/Guard liner on bottom then a couple inches of packed sand on top of Armor Shield/guard. We also purchased the foam pool cove.The water is level and we do not see any bulges in any of the side walls. We contacted installer right away and his only comment was "looked like some of the sand had been washed away from under pool". He has not returned any other texts or calls from us regarding this matter and now it is Spring 2015.We are unsure what if anything we need to do or will the pool liner be safe from ripping (from metal base plates) since we used the Armor Guard/Shield underlayment. We are also unsure as to how sand could have been washed out from under pool when Foam Pool Cove and Armor Guard Liner was used and sand was put on top of it.Any advice, suggestions would be appreciated as we are considering draining pool and adding more sand, but then run the risk of having to replace the liner and it is only 2 years old. Help please.Thank youHi Julie From what I can see in the photos and what you have told me the pool should be pretty safe. The pool pad should be protecting the liner as long as you don't feel anything sharp.The sand did not leave the pool, the ground settled around the brace assemblies because it was not packed enough, I've seen it a hundred times.If it is not getting any worse, and if you can deal with cleaning a liner like that, it should be OK to use.If you are going to try to fix it you will want to do that soon. Don't do it until the weather warms a bit, at least another month. At that time be sure to leave at least an inch or so of water in the pool. Get a few helpers on the inside of the pool to hold the liner back while a couple or people on the outside toss in some more sand and smooth it out. Done this way, on a warm day, the liner should be fine. After about the third season you might as well just plan on replacing it, they start loosing their elasticity.
