Going to put up a intex 18 x52 ultra. Now the question is this...I would like to build a 22x22 frame using 6x6 post for the frame. Inside of the frame use crusher rock, compacted to one inch of the top of the frame. Put 1 inch foam on top of the crusher rock along with the pavers, and place pool on top of the foam. Wife is kinda of getting tired of the mud pit around the current blue tube pool we currently have. We will be taking down the ultra down at the end of the season, just dont trust it up in the harsh winters we"ve been having here in Mo lately...oh by the way the frame would only have to be one row tall, maybe 2 rows in the back section depending how much rise is in the ground...Thanks for the feed back and if you have any pics similiar to what Im thinking ..PLZ post em
