Hello. I just want to share my pictures from our DIY install of our Intex Ultraframe 12x24x52 rectangle pool. My mother and I completed most of this work ourselves. My husband helped some but his job keeps him away from home most of the time. We had to dig in to get level ground. We shored up the sides with stakes and pt lumber. We packed in granite sand by raking, wetting, tamping and screeding. We used a transit to shoot the top of the box and then I built a jig to screed. We buried pt 2x12x15 and shot grade using the transit on each of the 18 leg supports. ]I think it's turned out great so far. Next will be our deck.
