Vinyl Fence Install Help

[vinylFenceGuy]

I'm fixing to install a vinyl fence. The posts are hollow and 5x5. The rails slide into the posts so they cannot have a 4x4 inserted into the post.

Question, I see everyone stating to drop the post into the hole, then backfill around the post with concrete. Why not fill the hole with concrete, then drop the hollow post in so that concrete will be inside the post and around it in the ground? Am I missing something?
Thanks!

You can do it. Easier to assemble the fence and brace it where it should be and then fill around it. I have seen some rebar put through the post in the concrete. Not sure if it’s bad or not

I think the idea around these type of fences is they are designed to come apart in high wind storms. Since they are solid panels and if you filled the post completely with concrete then it becomes too sting and a big wind storm will break the panels and not be reusable. If they are installed correctly then they will fall apart in high winds and then can be easily put back together

I installed the same fence you mentioned 2 years ago. Here is what I did:

1. I placed the post into the hole
2. poured dry concrete mix around the post
3. used a safety cone as a funnel to pour dry concrete mix inside the post to just below where the bottom rail goes into the post.
4. spray water into dry mix

For end post or gate opening, I used a 2"x4" on both side of the rails.

The high wind story doesn't make any sense to me. If a wind is high enough to blow the fence down, that fence piece is in the next county. How are you going to find it. Insurance is not going to pay anybody to find it. They will pay for new one. I would fill whole with concrete and then push the post in and position the rails before it dries and make sure you use a level and a string for straight as once it's set you are up the creek on changing it.

I put up a 50' section of the 6' high privacy vinyl fencing and all I did was dig a hole, dropped in the post, filled around it with dirt and the inside with dirt, no concrete. The fence has survived some strong winds and has not moved and is just as straight today as the day I installed it 5 or more years ago. I figured if something happened and a post gets busted I didn't want to have to deal with a chunk of concrete to replace a post.

Follow the manufacturers directions for installing the post.
