We have been living in our house for about 3 months now, and this morning I noticed that the anhydrite screed in our dining room is "moving." When pressure is applied, there is a creaking sound in one spot in front of our floor-to-ceiling window. The tile covering does not sound hollow, and everything looks "normal" from above. Is this something you just have to accept? I've heard that screed can continue to behave like this for years. When should I start to worry—apart from the noise, which is annoying...
I would appreciate any ideas. Oh, and of course, we only installed the floor covering after the recommended residual moisture level was reached.

this is probably caused by the "upward curling" of the screed, especially around vertical connections (walls, also full-height windows, joints in door transitions).
This means the screed is warping upwards at the edges due to drying. The cause is internal stresses on the screed surface.
Usually, this creaking noise is harmless if the joint at the window can absorb the stresses. Once the drying process is complete, the creaking will stop. How long this takes also depends on the measured residual moisture.
What does the joint look like (material?), as the transition from the screed to the full-height window?
Question: Which method did you use to check the residual moisture in the screed?
The most reliable and practical method is a so-called CMG measuring device!!!
With anhydrite screed, you also need to be careful that little water penetrates the screed, because although anhydrite is more cost-effective to install, it is much more sensitive to water than cement screed once installed. (The joints in the tiles are never waterproof since they consist of mineral-based grout.)

Thank you for the prompt response! I am not familiar with the joint material – "blue insulation strips"...
The residual moisture was measured with a CMG meter! Well, I hope it really dries out on its own – we don’t have any "water features" in the dining room :-)

What Thomas wrote is not correct.
An anhydrite screed does not cup because it does not expand like a cement screed; on the contrary, it contracts.
I have another suspicion. When was the "blue edge strip" cut? Before or after the tiles were laid? If it was cut before the tiling, I hope it was not cut flush with the screed. Because if so, some tile adhesive might have gotten onto the wall, which could cause creaking when walking. The baseboard should be removed and this checked.
This should be done by the tiler. So please contact your architect or builder.
Regards, Michael

As far as I know, the strip was cut afterward – but I can’t guarantee that for sure.
I will keep an eye on the spot since it doesn’t creak all the time, as I have noticed by now. But thanks for the tip!

Unregistriert-114 Jan 2008 18:25We built our semi-detached house in 1999. The screed in the upstairs hallway has creaked from the very beginning. Recently, I asked a screed specialist for advice. He suggested pouring synthetic resin into any existing cracks. That should stop the creaking. Once our glued carpet is worn out, we will take care of it.
