Another Concrete Floor Question

[wcavanagh]

So I am buying a house, well cottage. It was built in 1900 and is in Scotland, solid wall construction. Suspended timber floors in 90% of the rooms, and due to damp, and age most have failed.

So as part of the renovation, I am going to have to replace these floors, Mrs. is keen for underfloor heating throughout, so I am guessing concrete is my best option here. Question I have is a moisture barrier enough to put in before filling, etc, with solid wall construction.

I plan to build new stud work throughout with vapor barrier etc.

Someone suggest block and beam also. We are looking at 160 square meters of flooring approx. I plan to do as much labor myself as I can. I have done many renovations, but never replaced a suspender floor for a solid one before.

You have to consider the location of the property - is it on a hill side etc.

You also have to consider that solid floors can divert moisture into and up the surrounding walls - altho 1900 should have a DPC.

Solid floors need insulation in the field of the floor and at the edges.

Re-running of pipework and cables has to be considered.

Thanks, its a full gut and strip, so I will be rewiring anyway, so no issues with that.

The wall construction is solid stone about 700mm thick.

I aim to insulate the property to a high standard, as it will be oil heating I install.

I am clear on all the other work, just never done floor work, other than repair existing timbre, but these are in very poor shape.

Concrete floors will accommodate UFH - research diagrams on here, and use google. As always: its the FFL that determines all floor work.

700mm walls most likely will have a rubble infill and no DPC - search for one (it would probably be slate) just in case.

Using "stud wall ... with vapour barrier" is a fraught and contentious issue - read and research on here and the views of other Remedial experts on google, and come to your own conclusions as you are apparently a skilled man.
