Joint foam in gap or not

[evoline]

Hello,
I'm helping someone and in the garage, the concrete floor looks like this, with about a 3.5cm gap to the wall.
Is it okay to use foam sealant in the gap?

I will be putting up shelves later; I don't want anything to fall into the gap.

Thanks in advance

Is the floor damp?

Is the floor damp?

No, I don't think so, but cold.
I don't know how it is in the gap.

Is it possible to fill it quickly with something like foam sealant?

Thanks in advance

Yes, you can use foam, but foam sealant absorbs moisture and it will then lead into the wall that the foam is against.

Yes, it's possible to skim but spray foam absorbs moisture and it will then be led into the wall that the foam is against..

Ah, I thought it didn't absorb anything, can you put some paper in and then spray foam over it?
Is there anything else you would recommend to fill the gap?

Thanks in advance

Self-leveling compound is quite easy to work with, and also cheap.

What is under the wall? Beam directly on the ground? Concrete? Leca?

Foam sealant can work excellently. Depending on which foam sealant is used and how the construction under the wall looks.

Yes, you can use age-resistant plastic against the sill or tape with green tape and then use expanding foam to protect the wood.

It's fine to put a strip with

I don't know how it is under the wall right now, I'll check when I'm there again.

Does this expanding foam work?

Otherwise, self-leveling compound as someone else mentioned, is it just about filling it in or is there something you need to consider?

Preferably no list or rule, because the shelf and workbench should be able to be directly against the wall.

Thanks in advance.

Find a foam that is waterproof. This one may work if it's warm enough when applied.

Edit: if you want to be completely sure, use the two-component foam that @Jansson69 linked to.

Thanks, I'll go with the one from Biltema you linked to.
