Hi guys - long story short, we had natural timber flooring installed in our 80s home. The installers removed the carpet and ripped up the ceramic floor tiles in our entryway - photos of the removed tiles below.
I'm wondering what the white concrete-like material stuck to the bottom of the tiles is. To my limited knowledge it doesn't look much like mortar as there are no trowel marks.
Reason I want to know is because in hindsight we should have checked if there's any asbestos behind the tiles. The white material in the photo tested negative for asbestos but is there a possibility that it was used as glue to attach to some AC sheeting underlay? Or is the white stuff pieces of the actual concrete slab floor?
I can't remember whether the installers sanded the concrete to remove any glue before installing the timber..
Wish I could rip up the timber floor to have a look underneath! Any advice appreciated
