Re: Greenhouse leveling question
Years ago there was some junk on the market called something like 'post hole concrete' or 'fence post
concrete'. But that is no longer sold here, probably because some people used it where they shouldn't
have and got into trouble.
If concrete was as fragile/soft as you guys describe it, all the concrete structures on this planet
would have collapsed, long before construction was even finished.
If 'Blown' has railroad ties or 6 x6es readily available, by all means use them, but as base of a light
weight aluminum structure it is overkill, if you have to buy them.
