How to repair/replace this column/post

[Arvida]

Hello,

As the pictures show, this post/pillar at the entrance has moisture damage at the bottom near the ground. I think it's improperly constructed; they should have set a concrete post in the ground and placed the wooden pillar on top to prevent moisture from the ground being absorbed. How should I address this now? It supports part of the rafters. I can't just cut it away and replace it, can I? Will the roof collapse if I do?

You place a temporary post next to it while you fix a new one with a foundation at the bottom.
Remember to use syllpapp or similar between the concrete and the wood.

You set up a temporary post next to it while you fix a new one with a base at the bottom. Remember sill paper or the like between concrete and wood.

Hi,

one more question. How load-bearing is this column? I wonder if it's possible for me to cut the column in the middle and set a concrete base, replacing just the remaining bad part. So not replacing the whole column, just the part that's bad. Will the roof collapse during the time I'm doing this?

I know this is probably not professionally OK but I think it's a shame to replace an entire 3-meter column just because 10 cm at the bottom is bad.

How load-bearing the pillar is cannot be determined from your pictures. Upload drawings or more comprehensive images so you can probably get better answers. Cutting and inserting a plinth might work if you do it safely.

Place the temporary pole beside.

But it's not a bad idea. Brace next to it, cut the post a bit above. Oil the end grain and paint. Dig out, place a casting tube, mount a post shoe and cast. Wait a few days and then remove the brace. That's how I've sometimes done it when building, very simple, the footing and post shoe definitely end up right.

Hi!

Should the post shoe also be cast? And why? Then I wonder what happens to the water that ends up at the bottom of the post shoe? Won't it damage the column again?

I thought the correct way was to put a sylpapp around the column and then straight into the post shoe,

I don't quite understand what you mean. But it sounds like a solution that retains moisture. The post support is drained at the bottom. Placing the post directly on the concrete probably requires a paper in between. But nothing folded up around the post.

The post is well under the roof, so there won't be large amounts of water getting into the post holder.

No, the post base is not cast, it is attached to the post and in the concrete. https://www.byggmax.se/stolpsko-p238045 You should have syllpapp under the post.

Thanks for the answers, now I understand.

You should have sealing paper under the post.

Hi,

the problem is that the post is 145x145 mm. And there are no post shoes in that size. Maybe that's why it was built the way it was?

what should one do?

Either you make a special post shoe or saw the post 95x95 about 20-30 cm up from the lower end.

It's really enough just to unplug for the stolpsko.
