Great video! I can’t for the life of me find any info on how deep the footings should be for something like this. I am build a large privacy screen with 3 tall posts that will be anchored to a roof. But I want to make sure the footings are deep enough.
It depends on your area. Check with your cities building department if you can. I used to think footings were for spreading the weight, but they are actually more for holding things down because of wind. My pergola (another video) required 16" square footings. The grape arbor is just holding itself up, I probable went down 12-16" when I first built it.
The website states "Fastener holes are slightly offset to help prevent fastener interference". I just measured mine, the holes on one side are 3/8" higher than the other side. If the screws are going in straight, they won't hit each other.
I wouldn't use shims, to easy to rot or fall out. It has two sides so there is enough play in the fit that you should be able to get your post plumb, unless the concrete pier is way off.
Can you describe in more detail what you did to have the square block (precast?) with threaded rod in place? Did you pour concreter underneath or was concrete there that you somehow attached the block to? Really nice and clean solution!
Thanks for the comment. I needed to raise the post 4" because I was changing my dirt level. Since there was already an existing footing there, I just cut and bent the old post anchor, then cut an 8" concrete block in half and set that over the existing footing. Then set a 5/8"- 4" bolt and washer in the center and filled in the concrete block with some cement mix, filling in the spaces between the old anchor and new concrete block. Using a concrete block does make a nice-looking footing for a post if it is going to be above ground. 8" is really too shallow but you could stack two blocks to make a 16" deep footing.
@@BruBuilds Thanks for the reply. so it sounds like you had a stub from the old anchor, added the 4" bolt and used concrete to bond those to the old footing. The pergola posts we need to replace were put in a hole with poured concrete around them. They are rotting above the ground. Thinking we will cut them off and either break up the concrete. use a farm jack or dig it up. What would you recommend in terms of replacement? I kind of like the idea of the post being above the ground in a bracket, but expect just using same method would last for 10 or 20 years. Thoughts? Thanks!
