What kind of attack is this?

[Rammega]

Hello. I discovered that my plastic floor on the existing balcony floor had started to sag. Then I found this infestation. What is it and what should I do?

there is something growing because it is constantly wet there, like............It will probably eat up your balcony in the long run if you don't address the "wet" and why it is so.

Ok. It's like when spring comes, there's snow on the balcony for a long time. And the snow melts now and then. Could it be that? Otherwise, it's sunny side all the time during the day.

Considering how the attack looks, it seems a little wetter than just a period in the spring. That's an active attack, kind of. Do you have more pictures? Where does the part that's to the "right" go? Not the underlying part but the one that's most affected.

What you see is an attacked extra reinforcement of a 120x45 beam that rests on a substantial beam type 200x45 that extends all the way to a 95X95 post holding the railing in place. The others are not attacked, but both beams are rotten at that spot.

Make sure to create a lighter construction that dries out faster now that you are replacing the rotten parts. Assume that it is pressure-treated beams that have still rotted.

Make sure to create a more airy construction that dries out faster now when you're replacing the rotten parts. I assume these are pressure-treated beams that have rotted anyway.

Yep. Just go at it with the crowbar and remove the junk. Thank you all for the answers.

The white stuff looks like some kind of fungus. In the latest pictures, it also looks like you have the same kind of fungal attack on several parts of the balcony.

Yes, it has spread a little outside the rotten area. What should I do about it? Can I burn it off?

spray on for example boracol or chlorine

 

[Stefan1972]

Spraying on something doesn't matter if you don't address the root cause of everything. Mold and similar spores are still around us in the air constantly. If you address the worst and let it dry out, the growth dies off on its own. If it continues to be wet, it thrives further.........

A little continuation on the moisture issue.
I have now removed the piece that was very moisture-damaged.
It has rested on a 95x220. And it has also taken a hit from the moisture. What would you do besides replacing the entire 95x220 piece?

 

[Janus82]

The best solution is, of course, to replace the entire beam so that it is fresh and has full strength. An emergency solution is to attach a new beam on top of the old one. Make sure that the new beam extends well past the posts on either side of the damaged area so that you can transfer the load between the beams.

I think so too. The 220 rule is about 10 m. So it gets help in several places to relieve.
