So there's a big difference in Quikrete tubes and others. I am using the heavy stuff, but hearing differing opinions about how to install them under elevated posts. I bought 12" diameter, and need to extend above ground 12". Was planning to counter sink the tube 2 feet. Read somewhere that it needed to make soil contact below so a couple of inches of gravel was not advised. I am not sure about that part, as it would provide drainage I was thinking.
Does anyone know if that's the correct procedure?
