I've been lurking here for a while and have pulled some excellent information from the site.
So far I've leveled the area that the pool is going to go, added two inches of stone dust and compacted it, and have all my sand in the middle. Well two nights ago, we put up the walls and stabilized them with rope until we leveled the sand and put the liner in.
Well, last night came the wind and I woke up to a collapsed wall. And to boot, I came down with the flu today. So I have the wall mostly rolled back up and will try again next week when I'm off.
Just thought I would share my misery's with everyone. Thanks.
