My uncle told me to always set posts in wet concrete, even in clay soil.

Tried it on a job in Spokane last week and now I'm dealing with three leaning sections after a heavy rain. Anyone have a better method for wet, heavy ground?

Gotta disagree on the gravel collar, that just makes a bathtub for water in our clay. We dig deeper, set in concrete, but leave the top foot of the hole open and backfill that with pure clay packed super tight. Acts like a seal.

That Spokane clay is like setting posts in wet soap. My crew switched to using a gravel collar at the base for drainage, then backfilling with the native soil.
