First, why would you want this? Just get an above ground pool, much cheaper. It would be a bad idea because you would not have the sand packed around the edges, a pool installed this way would constantly be unlevel. Every time the ground shifted, froze, etc it would shift. I don't even think it could be filled without leaning to one side. Just not a practical good idea. But, that is my opinion. I am not a pool installer, just an engineer.
