Hello everyone,
the following pictures show an adhesive layer underneath carpet and vinyl flooring that was found in our renovation project.
Of course, we will have samples analyzed in a laboratory.
However, I would like to ask about your experiences with asbestos and such adhesives... Does it look like asbestos to you? The texture is extremely hard and brittle.

Thank you very much for your support!

Sorry, I completely lack context here (what is shown, from which perspective, and at what scale). "Zoom instead of context" is always a bad approach to engage fellow participants in the discussion.

Feedback is always important!
This is a section of the floor structure that has been removed and placed upside down, which is why the order is reversed here, from bottom to top: cast asphalt, insulation board (possibly wood fiber board?), and finally this type of felt paper (possibly asbestos felt?).

These white beads around the edge appear to be leveling aggregate and form the first layer of the floor structure.

The house was built in 1975, using solid construction methods.
If anything is unclear, feel free to ask again.

Does this look like a wood fiber insulation board to you?

To be sure, I would always consult a professional (surveyor) for advice.
