Moisture - impact on aerated concrete floor under bathroom?
Hello!
We are in the process of selling our house, built in 1964, 1½ stories + basement. Structure + beams in lightweight concrete (ytong).
In the bathroom, we've had a drain with poor drainage.
Therefore, we've been quite careful with bathing, but we have children - so we've had flooding a few times, which has resulted in paint peeling on the ceiling of the basement under the bathtub.
Since we had a professional drain cleaning done in the spring, there have been no problems with the drainage.
Beams under the bathroom according to the technical description:
"Tongue and groove beam slabs of lightweight concrete, topping with slope towards floor drain, membrane insulation, setting mortar, sintered tiles"
In the bathroom, there are mosaic tiles (?) on the floor, but under the bathtub, there are no tiles. I painted the surface with wet room primer when we moved in.
Now the question - which the buyers have asked:
Could the water have affected the strength or had any negative impact on the beams?

No, not as you describe it. It can have an impact if it has been going on for a long time, several decades.
The most common issue, as you have noticed yourself, is that the paint peels on the underside, on the other hand, a good indicator that it is getting damp again and needs to be addressed.
How old is the finish in the bathroom?
Was there a bathtub before you moved in as well?

Hello
The surface is original. There are no tiles under the bathtub itself. When we moved in, I painted the area there with waterproof primer to provide some protection - the plan was to renovate the bathroom when the children got a little older... but instead we bought a bigger house.
There was already a bathtub, but the house had only had one owner before us - the couple who built the house in 1964 - and for the last 10 years or so, the widow lived alone in the house.

Then there should be no structural problems.
And since the surface is original, there is nothing for the buyer to directly remark on; it is not renovated, and therefore the age rules apply instead, and they can expect a condition corresponding to 60 years of use.

There should be no danger. What can happen with a concrete floor exposed to constant moisture over a long period is that the reinforcement can start to rust. The rust expands and cracks the concrete. This is often seen on balconies, where it is also accelerated by freezing. For rust to occur, oxygen is needed, so cracking is required for other reasons, such as freezing.
If the moisture only shows as damage to the paint on the ceiling, then there hasn't been an excessive amount of moisture. In more extreme cases (where there is still no danger to the concrete), you get moisture-dripping surfaces throughout the room under the water damage.

Talked to my wife and she has a much better memory than I do. The leakage down in the basement occurred only before we replaced the floor drain, a year or so after we moved in. After we replaced it, it hasn't leaked into the basement. However, there has been standing water in the bathroom a few times due to the poor drainage from the sewage, which was addressed with a flushing of the sewage this year, but it hasn't run into the basement.
