Hi,

I'm preparing to renovate my 1930s first floor flat. I was intending to relocate my pipes which currently run along the walls, to under the floorboards. I have lifted my hallway floorboards to find that an inch or two under the floorboards is solid concrete. Baring in mind this is a first floor flat, I would have thought that concrete was too heavy. Does anyone have experience of this and know whether it is normal practice to have concrete under floorboards in a flat?

Thanks in advance,

Sophia

Hi smorzel,
No it’s not normal but in instances where ceilings are lathe and plaster I have seen it used to stabilise the mortar squirts through the lathes.
