Hi everyone,

now a question for the experts here:
We have water damage, see another thread. Now the question: what is actually the method of choice to measure the moisture level in the screed insulation?
When the measurement technician was here, I was in the office and my wife at home. She said later that he did not go down the walls (through the edge insulation strips) with any measuring probes and ultimately only measured with "a small box on the parquet and the tiles". On the phone they then told me something about "neutron measurement"!??

At first I thought, "cool, now they’re already turning your hut into the new final repository" so I quickly googled: Ok, it does appear to exist and is also advertised as a great method for moisture measurement.
But it really seems more like something for professionals and analyzing the measurement results is not easy.
What made me suspicious, though, was that he apparently only compared at a few spots and that was it. Whether there were water pipes or ventilation ducts in the screed insulation, he could not have known at the time, he only got the plans afterwards. Can you get valid results that way?

So: Is this now the normal method of choice and does it really work that easily and smoothly, or does it rather sound like someone who didn’t really know what they were doing?

Best regards,

Andreas

Hello Andreas,
drillings will be made at the edge or at places that do not pose a risk to the underfloor heating. (but rarely)
Completely normal devices for moisture measurement and no luxury devices. :-)
Best regards

Hello Andreas. The procedure apparently used by you for recording a moisture grid with the neutron probe is a non-destructive method, and an excellent one in terms of accuracy. It is not only an expensive procedure but also requires proof of qualification for the operating personnel, as well as storage and transport permits. The procedure achieves a measurement depth between 10cm and 30cm. Installations embedded in the floor structure do not interfere with the procedure. However – and I agree with you here – a measurement grid of point-shaped individual values is recorded, so that after transferring to a plan, an overview of the moisture distribution is obtained. What was done now and how in your object I am not able to assess. --------------------------- Regards: KlaRa
