Our neighbor's trampoline decided to take the plunge....in our pool!

[lmfoss]

Well some days I really wonder if we were meant to have a pool. We ordered it back in Feb 2011 but because of a truckers strike and a "recommended by the pool retailers" installer, we didn't have a pool until October that year. The installer the retailer recommended was an idiot and left our side walls up but not connected during a fierce thunderstorm to twist in the wind and nearly fall into the deep end. Besides that our pool was supposed to be only out of the ground 2 ft but since he couldn't figure out how to dig down deep enough we ended up with a hybrid 4 ft pool with a 7 ft deep end. A couple years ago ice cut a huge gash in the liner and we had to replace it then last year in August our neighbors trampoline blew over his fence, our fence and over our deck railing to land in the deep end of our pool. We knew we were losing water but it rather than try to fix a deep end leak we waited until this spring to address the issue. We are in the process of getting quotes for a new liner-his insurance will pay- but we are wondering if at the same time we shouldn't add some kind of underlayment and side wall insulation (at our expense). We have a grout/mortar bottom and sides up to the metal walls. We've been reading about rigid polyurethane foam would that be good to put between the mortar and the liner? if so or if there is something better, how do you attach it?

Thanks for any advice our pool is 15' x 30' Foxx oval with surrounding deck

Hi Allen,

We live in northern IL about 60 miles SW of Chicago in a town called Sandwich that no one has ever heard of. Well the reason we were thinking of an underlayment was to add cushion to the feet possibly help prevent any further bottom damage. We will install wall foam at the same time to protect the liner from any rough spots on the wall. We just don't know whether the underlayment is a good idea or not since we cannot find anyone who has done this on a mortar base. If you have any advice we'd very much appreciate it. Thanks!

While no one may have heard of Sandiwch IL now that your location is in your profile one click brings up a map for people to find out....

@zea3 @Casey @Bama Rambler what do you think about underlayment for cushioning and wall foam on a AGP?

There shouldn't be any rough spots inside the pool wall, but if there are check and make sure its not rust. If it is from rust it will need to be treated and neutralized or removed. I don't know if wall foam gives any real advantage. Maybe it could help prevent ice from slicing a liner? I have not heard of anyone with a deep end in their AGP using padding on the bottom. You may have a hard time keeping it in place before the liner goes in.

For the wall foam we were thinking of it more for insulation to keep the heat in the pool as we do run a heater in the cooler months. If we find rust what do you recommend as the best way to deal with it? On the rigid foam for the base we were thinking of gluing it to the mortar bottom. Funny you should say the wall foam might prevent ice damage since our original liner was sliced by ice.
We've now noticed that the track that holds the liner is pulling away from the wall in places so that will also need repaired. It's frustrating.

I don't know for sure if wall foam will prevent ice damage, I was just thinking it might provide a slight amount of expansion space, but wall foam is pretty thin.
If you see surface rust on the inside wall scrape it off with wire brush, sand paper, naval jelly, or a grinding tool and treat the area with a rust inhibitor. Even if the wall is in good shape I would add a coat of rust inhibitor as long as the liner is getting pulled anyway. If you can't get the rust off use a rust converter to neutralize it and treat the surrounding area with rust inhibitor.

I wouldnt waste your money on either. You're going to have to cut the foam boards at angles to fit the break lines and that in itself is going to be a headache. I've heard the wall foam will hold moisture and accelerate rusting. Plus the cost of everything right now you may as well as plan on selling your first born to fund it and you still would owe on the bill. Just clean the bottom of loose stone or dirt and drop the liner. You want heat, invest in a solar cover. Use it at night. Itll keep the pool warm. I use mine every night n uncover daily.

Thanks for your advice. We probably will ditch the idea of the foam. We had a solar cover and it was a pain and didn't last long but we may try another. We have a gas heater but our gas prices have gone up 160
% recently so won't be heating much. The liner replacement will hopefully be paid by the neighbor's insurance company. After noticing the bead receiver track is pulling away from the pool wall, I'm just hoping we don't have any more unpleasant surprises.

Off topic...how do you like your slide?

Absolutely love it!!! The kids love it the most. They have to sit on their bums going down n they are pretty good about it. I like to hear the slide water hit the water when I'm out there by myself. I've used it and its fast!

Very cool, I'll put one on our list of things to get for the pool
