QuoteI'd keep the tubes up off the bottom a few inches - 4 to 6 so the base could spread to around 16" dia depending on loading and soil conditions (provides better support with lower pounds per square inch due to bigger area = less chance of settling). . Pour a bit first and let it get firm to seal the bottom of the tube - then pour the rest with a couple 1/2 inch rebars to hold things together - or as suggested by an engineer or architect if necessary. Put your chosen anchors or bolts in the top at required level.
QuoteOn another topic....I was in Menards the other day and saw that they had some sort of "composite" beam that is about the size and shape of a railroad tie. It is extremely heavy, but says you can nail and cut it. I need to do some more checking to see how weather resistant it is, but could that replace the cement tube?? Maybe with a cement footer to level it?
Quote(I figured it out.... it's over 130 bags of concrete mix if I do it by hand!) I don't mind buying the bags....just don't wanna mix that much! I'm not sure a cement hauler would have the patience to fill 24 sonotubes for me, would he??
Quote6 bag is a strong mix - six sacks per cubic yard. Air entrainment should help with freeziing if I remember right.
