Hi!
Currently installing a pool up in Sudbury, ON, and am wondering about options for insulation. I'm putting in a pool with 42" walls and a ~8 foot deep end. Because our ground conditions weren't the best, we dug down to bedrock (over excavated by about 5 feet all around in order to build up a good base for the walls to sit on) and then backfilled with Granular A and compacted very well. We will be digging out the form of the pool from this base and then putting down a thick layer of ground/Portland mix (3:1) as recommended by our pool supplier.
My question is: What have other people done (or what do people wish they'd done) for insulation around the base of the pool? My plan is to spray foam the outside of the steel walls as well as the lines running to the pump/heater, but what about the rest of it? Can you spray foam the granular before putting the grout/Portland down? Or spray foam over the grout/portland mix so the spray foam would be between it and the liner? Other ideas?
Thanks in advance.
