Welcome to our forum.
I threw down a frame on the bare dirt, leveled it, fitted it half way with concrete, threw in a bunch of wire coat hangers for reinforcement, mixed and poured some more concrete, realized I was about 2 bags short, so threw in some chunks of old Broken concrete, finished it off with the remaining concrete, skreeted it off, and my hot tubs (2 actually) been sitting there fine and dandy for 26 years.Take THAT Tman hahahahahahahahha (seriously, that's what my hot tub sits on.To anyone that, unlike me at the time, DOESN'T get free hot tubs, I DO NOT recommend doing it "my way"!
