ᐅ Screed Drying / Moisture

Hello,
We have had the screed in the house for just under two weeks. Today, I noticed in one corner of the bathroom, where the recess for the bathtub is located, that moisture is collecting and rising up the wall. The underfloor heating is running in drying mode. Could this be caused by moisture in the screed, or is there another issue?

What does your site manager say? I would contact them first.

I think drying without construction fans is hardly possible right now due to the high humidity and rain. At least here, we have had 4 running continuously for 5 weeks. Our neighbors, who installed screed during the winter, also managed to remove all the moisture through ventilation.

Without making a professional assessment, I can’t imagine that the screed would be damp in just one spot. Especially since it doesn’t seem to have direct contact with the wall there, or am I mistaken?

Could you take a photo of the room, especially the area where it was separated for the shower/bathtub?

Construction delays, yes... but I wouldn’t worry just yet. After only two weeks, some houses already look like a dripping cave. Here, I would rely on my crystal ball and suggest this is due to the capillary action of the sand-lime brick, and simply wait for it to disappear over time.
