Floor preparation - suspended floors

[Andy Allen]

I've just re-read the thread......not clear if it's chipboard or floor boards.
I would say if it's chipboard it's probably a floater , floorboards probably on joist..

if it's floor boards on ground floor probably an older house, which could be fairly easy to reinforce .

So far as I can see it's tongue and groove boards. Actually I said approx 27m2 but I think half that area is screed so hopefully less bounce being a smaller area.
