I am renovating a bathroom on the top floor of a period block of flats.
It was last done in the 1980s (my guess). I took up the vinyl, and removed the chipboard beneath. Under that was a lot of dust and what looked like loose dry rubble.
I swept all of it away, to reveal what looks like concrete between the joists:
Is this a usual construction? The concrete is very "crumbly", although the joists look ok-ish (I am not entirely sure what to look/test for).
I am unlikely to need any of the underfloor pipework in the new bathroom layout (plan to run it in a box around the edge of the room for simplicity).
What's the best practice for renovating here? Remove the concrete? Keep it and build over? I intend to add underfloor heating (wire) and tiles.
Thanks!
