Tried gravel boards instead of setting posts deeper on a wet site in Memphis
I always dug 4ft deep for fence posts until last week when a job near the Mississippi floodplain had me swapping to concrete gravel boards and only 2ft holes. The old timer on the crew proved it by showing me a 10-year-old fence still standing straight with no rot at the base. Anybody here switch to gravel boards for dealing with wet ground or do you stick with deeper posts?

@gibson.sean is right, even cheap gravel boards outlast deep posts in muck because water ALWAYS finds a way around concrete.

Used to think pouring concrete deep was the only way to go, but seeing how water just creeps around it changed my mind. Gravel boards seem like they let the ground breathe and shift without trapping moisture against the wood. Seeing your posts makes me want to switch to that setup next time I build a fence.

Been using gravel boards on wet sites for years now. Saves your back and still holds up fine as long as you pack the base good.
