Flooring is by no means beneath me, but I haven’t really done anything below a shoe molding. So question for the tile high club: What would you do in the pictured situation? These are floor sections that have always felt a bit “squishy”. Today they finally popped up into the tent formation you see here.
Wait for it to settle and then add glue to keep it down? Cut it to fit?
Additional context:
I did not do this install myself, so the history is a bit of a mystery. This is installed in a full bathroom and is made of what feels like a smoothed slate material. I believe it is a composite tile.
More photos for context:
That is an utter mess of self-leveling compound poured way too thick all at once, not fully covering the area, and then not using a proper thinset base. I guarantee the rest of that shitshow is going to go the same way.
That needs to be torn out, the self-leveling garbage pounded out, proper plywood laid in and screwed to the joists for the majority of the space to get taken up, then maybe a thin layer of self-leveling if needed. A layer of Schluter uncoupling membrane can be used to disconnect the expansion of the walls and floor from the tile, with appropriate gaps (like 3/8") around the tile and hidden by the baseboard, with a snap down transition strip at the door that also allows expansion.
And then find whoever installed that and slap the bejesus out of them.
I’m working on finding out the contractor so I can ban them from my coop.
The way it separates in clear lines between the tiles, it looks like it was applied to the tiles, not to the floor. So I think they didn't use self-leveling compound at all and just put on ridiculously thick globs of mortar to raise the tiles to the desired level.
