New Pool Install - Very confused

[kevincad]

Ok we get our pool soon and the ground work has started. I posted a post earlier about patio stones under the wall supports. And it seems like most have done that by what was replied and what I have found on this site. How ever why then do some people say not to. As the dealer I bought the pool from. When they do installs they do not do that. His explanation made great sense. We live in Ontario Canada and we get snow and frost in the ground. He said with patio stones you are more likely to get some to lift on the stone with the frost and maybe damage the pool.

2ndly - Do you just level the ground and then set up the track and the wall on the dirt and put the sand inside the pool? 2" I have heard? I thought you laid the 2" of sand under the track and wall? So which is it ?

I am confused ?

If frost will heave the patio blocks, it will do exactly the same thing to the supports themselves.

Not really - patio blocks tend to go under the wall a bit, the posts don't, frost will likely work it's way around the slender wall and bulge up on eh outside - the post can heave all it wants without any problems, it's the wall you don't want going up - if your patio block is under the wall at all, the wall can either crumple there or push up causing you serious grief either way.

What the ?? we were told we needed 12x12 patio blocks for under our uprights on our buttress free oval. So how do we install those so they don't heave with frost? We live almost on the Canadian border and get very extreme winters. The whole area (Red River Valley) is notorious for frost heaves.

This pool claims it has more uprights and "oversized base plates for stability" Do we put our blocks under just the base plates or ??? If we don't need those blocks, I am bringing them back.
