As @Scaxx said, there is a support rod you use to prevent sagging during pour and cure, but if you were worried about it, I suppose you could use the actual lift table during the pour and cure, just pressing it up to the base without lifting, just supporting. I would think that would serve the purpose as well. Disclaimer is I haven’t done my pour yet so this is all conjecture.
@Bigdaddy2166 would be nice to know from those that have done their pour of how flat the bottom of the base is post-cure.
Finally got the concrete pour done on Monday and put the epoxy down today. Instead of the included gray tint, I used about 10ml of red tint. It gives a unique translucent look to the red where you can see the concrete underneath. If you want a solid color, definitely use more than 10ml. I think I’d have needed 20ml to make it solid red, but I like this look.
