I'm trying to figure out the best way to set 6 x 6 posts for a pavilion. I'm considering the two methods below. I know they both have their good and bad points. I believe the first will extend the life of the posts but will require extra bracing for lateral movement. The second will resist lateral movement but it will reduce the life of the posts.

    Correct on all counts. "Best" is up to you now. What's the question?

  • I'm leaning (bad choice of words) towards a buried post in concrete for the stability. I just don't want it to rot out in a few years. Apr 15, 2021 at 18:38
  • I prefer the pier and footing solution for ease of repair down the road.

The pier and footing is the best approach.
A structure, even a deck or pavilion should not have to rely upon the posts being anchored in concrete for structural support. The pavilion itself should be planned and supported to be structurally sound in itself regardless of the type of footing used. If properly installed with an anchored metal post base the posts will be stable and serviceable for many years. Otherwise,with a buried post when the posts rot, which they will, and if the structure isn't sound the only way you will know is if the structure starts to lean - which is not a good plan.

  • There are sturdier and less sturdy Simpson brackets. Take a look at the ones that embed in the concrete, rather than the ones that just mechanically attach. (One I use regularly is the PBS ZMAX.) Apr 17, 2021 at 15:18
