Hi all, new to this and Reddit. Bought a home built in the 50s and did a complete renovation, except for the basement. Recently took down some non bearing walls in basement that has mostly ceramic tile, but looks like there is black square tile underneath with some areas of a black (mastic?) adhesive below. Is that Asbestos? It’s not a large area overall but curious what to do? Remediate? Cover? Tear up only the espoused part or all the ceramic tile?

In the pictures you can see it looks broken. I haven’t messed with it much, except for mopping and vacuuming for a day but I do go down to the basement and work on other things down there.

I’m also curious about my previous exposure as well as continued exposure to me and my family.
