Risk of trapped moisture EPS in joists ??

[Viktor.J]

Hello,

Quick responses desired, I have craftsmen on site and incoming this week.

House from 1945, split-level with basement and living floor. On the living floor, we are going to pour EPS to then be able to self-level and finally lay tiles in the ice hall and bathroom.

I have removed the wood shavings between the floor joists. The tiler said I should wrap everything with plastic. It's done.
But the plumber pointed out today that there is a risk of trapped moisture when the waterproofing layer is applied in the bathroom later.

What does the expertise say? Should I use something other than diffusion-tight plastic?

Help, please!

Hi,

quick answers needed, I have craftsmen on-site and arriving this week.

House from 1945, semi-basement with basement level and living level. On the living level, we're going to pour EPS to then be able to self-level and finally lay tile in the hallway and bathroom.

I have removed the sawdust between the floor joists. The tile setter said I should encase everything with plastic. That's done.
But the plumber pointed out today that there is a risk of trapped moisture when the waterproofing comes on in the bathroom later.

What does the expertise say? Should I use something other than diffusion-tight plastic?

thanks!

it all ended with me finding very good information on gvk’s website. It states that it should NOT be age-resistant plastic. So I went and bought "thinner and non-age-resistant plastic" and redid everything.
