New Pool Install - Very confused

[matt4x4]

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.
