My AG 18' round pool instructions say to level the ground, then place the 2x8x16' blocks INTO the ground, level with the ground. They want the bottom tracks to touch the ground. This way the whole bottom railing circumference of the pool would be on the ground.
Then, they want a 2 inch sand base for the pool bottom. Then they go into the cove instructions etc...
Then I had a question to ask customer support about my pool. After speaking with them, they said do NOT place the blocks into the ground. Place the blocks ON the ground after leveling the ground. btw, I was transferred to an installer who was from the company. I respect his opinions since he does this daily. Anyway, he said to place the blocks on the ground, THEN place the 2 inches of sand up to the level of the blocks. He also mentioned shoring up the outside of the pool wall so the sand does not go out of the bottoms of the wall, or something to that effect.
OK Sounds good, except... How can I place the sand and tamp it down while the bottom tracks are in place? In this second option, would I not want to go all the way out to the 20ft mark of the circle with the sand to make it an even, non eroding, flat, level plain? Is it not neccessary to have a "sturdy", tamped down area directly underneath the wall bottom brackets, or is it good enough to just have the blocks holding the uprights to be sturdy? Sure, the uprights are holding up everything, but it seems odd the walls have the weakest area underneath them in this case. They would be on top of sand, and not even tamped sand at that. The first version would have them on top of the virgin ground.
One more point to my question to the installer. I had called him to ask if the 2 inches was absolutely neccessary, because of the height of the liner. If you add one inch, then the liner would be too short? If you added three inches, then it would be too long? Is this an exact science? It's a beaded liner btw. "J- bead" or something like that. The ones that snap in place. I was just worried about the height of the sand and the liner height to match each other. Then he gave me these other instructions. I almost feel like calling back to ask "Are you sure....?" Please help!
