A Fukttekniker...For example, Munters Torkteknik or Antisimex...costs around 1500-3000 for a simple moisture measurement with action suggestions.abel48 said:
Bigger investigations cost bigger money
..but call and check what they charge.Tile directly without any protective layer is what you should stick to, but I would have scraped away old paint and such before I started.
Good luck!
A moisture technician is what you need, with references.
Munters sells dehumidification equipment, whether this might influence assessments is for each to decide.
Anticimex and moisture, well you shouldn't criticize without good reasons, but I am still a bit hesitant. The impression I have gotten from their inspections is that they are primarily liability waivers during real estate transactions. Or inspections for worried property owners, and then they measure moisture in, for example, crawl spaces, check for mold spots in the attic, and complain that there is no mechanical ventilation. That is something one can do themselves. Whether they offer more advanced/qualified services, I do not know.
I have looked at your pictures again. What you see is that moisture is being drawn up quite high on the wall, higher than what you usually see. And this is an interior wall. Additionally, there seems to be more of a problem with the wall than with the floor, which of course could be due to the paint.
I wonder if there might be a beam under the wall that is in the groundwater. An experienced moisture technician can see if it is an unusual character of damage and can assess the cause. He/she also knows how high up you usually see the absorption in relation to how much water there is to absorb. (Note, I am not saying that the capillary rise varies. What I am wondering is how much water can be absorbed with various faults, and at what height the wall has time to dry.) If it is so bad that parts of the slab/beams are in contact with groundwater, more powerful measures are probably required than just tiling over it.
A dehumidifier is not a bad idea, but if the beam is in the water, the wall will never dry. Then the groundwater needs to be lowered or the absorption must be stopped.

Both Munters and Anticimex have both moisture technicians and moisture consultants...I don't understand what the problem is with these 2 companies...incidentally the 2 largest in Sweden....that Anticimex also has assignment inspections is a completely different matter...and the fact that Munters sells machines does not affect the potential cause of the damage?poiu said:
If a company sells devices to solve a problem, suspicious people like me might think it could influence their proposed solutions.
My assessment of anticimex is based on the rather sweeping responses their inspections seem to provide, a risk construction, that can cause problems, etc. And that "discussions" have begun to emerge around preliminary inspections after the ownership change has occurred. Otherwise, read what I wrote.
Whether it is an advantage that the companies are the largest is up to each person to decide.

but if there is a beam under the wall that stands in the groundwater, it has been doing so for 51 years without any actions being taken. It is visible on the wall where it has come off that they have previously repaired it with some kind of plaster or filler.
I mean if nothing serious has happened in 51 years then maybe it's not that serious, but I might be thinking wrong there...?

The current construction has probably "worked" for 51 years because it could breathe freely. This is often the case in old houses. It's when we change the conditions that things usually happen. With tiles and possible heating, it's a new era! Check the cause of the moisture first, and you'll have your "safe ground". Good luck!
Since plaster and filler are coming off, it hasn't worked in my opinion. If you tile the wall, it seems to me that it becomes tighter, as only the joints are open. If adhesive, grout, or filler contain unsuitable materials, you may encounter major problems depending on various factors like moisture resistance and alkali resistance.
