The house is old, the attic is new ... and a bathroom will go there.
The 6.5 cm thick screed lies on a styrofoam impact sound insulation with a foil that also served to fix the underfloor heating pipes.
Here you can see a spot where the screed is not yet complete (a level-floor shower will go in there).
The green plastic foam strip will be removed, the floor - up to the walls - will be covered with a sealing foil on the walls so that any moisture penetrating through the tiles cannot run INTO the floor.
So far, everything is as "normal."
Because I have learned here in the forum with amazement that there is a swelling paste that significantly increases its volume when exposed to moisture and thus seals joints, I think it would be clever to fill the empty space that is created when the plastic foam strip is removed with such a paste so that, if the second sealing protection (1st tiles, 2nd sealing foil) should fail, there is still a third seal that even - if water comes - becomes tighter than when applied (great system).
Any water that might penetrate would thus not run under the screed ... and I would find that cool :cool:
Strangely, the descriptions of the "Betonit swelling paste" (found under this name on the internet) do not directly mention this purpose and I wonder about that because it seems so obvious to me and if a company can advertise anything, they normally do.
Is there anyone here who knows "Betonit swelling paste" and can confirm or refute my theory?
Would be happy about that:
Wolfgang
