What is this wood?

[ND1984]

So......was about an inch of self leveling compound same width as the boards either side and underneath as suspected it runs pretty deep. I noticed the floorboards either side are just resting on the concrete.

I spoke to a builder and they said you could just break it down a bit, level it off and the replacement boards could rest over that secured in place with adhesive so as not to disturb the concrete and the structure of what's there. That was after I said it's not a section of the floor that will be walked on hardly.

Not sure if that's an option I had even considered.

Any thoughts guys? I was a bit gung ho getting rid of that top layer.....

That's a nicely constructed, traditional floor Nick.
If there's a screed layer on top of the hearth concrete then that's the way to go.....if it gives issues due to hardness a few grinder cuts would help to chisel bits away but it looks like its largely gone.
As I said earlier, there's no reason not to remove the whole piece, apart from shaking damage to the ceiling below so I'd definitely go with your builder.
Hope it goes well!

Thanks John. I'm finding that really, it's just nice to have somebody giving a bit of reassurance to you as you slowly tear your house to shreds. Haha. Have a good weekend
