Seal under walls/Which sealant?

[Dimu]

Hello,

I am going to build nivell floors throughout the entire house. I will need to seal under the walls.
There is sealing compound available from nivell, but I can't afford it as the house is 120 sqm, so I will need a lot of it. Do you have any tips on good sealant to use for sealing?

Very grateful for the help.

Any outdoor sealant should work. I think you'll find yourself spending around 70-100 SEK per tube for something of decent quality. Since it will be under the walls/floor, you need something that lasts "forever". Expanding foam can also be an option depending on how it looks, but with leveling it has to be airtight.

bought this to test seemed ok I thought. Is this something to invest in? https://www.byggmax.se/verktyg/lim-tejp-och-fog/lim/lim-och-byggfog-all-in-one-vit-p18016

Shouldn't it work with a regular acoustic sealant or a butyl sealant? That way you would significantly reduce the price.
