I have a 1930's kitchen floor, 1/3 concrete, then 1/3 floorboards on joists on brick pedestals on the ground chalk (void is about a foot deep), then back to concrete. Whole floor about 12ft sq.
I want to tile over both the concrete and floorboard areas, but where this was done before, the tiles cracked at concrete/ floorboard junctions. The concrete areas are solid, floorboards flexible, so I guess best approach is to remove the boards/joists and concrete in the middle bit(?).
If so, I believe I need to dig back to solid chalk or add hardcore if flaky, add blinding, dpc, concrete, jabfloor then screed, but have a couple of questions-
1/. Is this building-control notifiable?
2/. Is there an alternative not b-c notifiable (apart from 'don't do it'!)?
3/. I have a lead water mains pipe joined to copper under the boards. I guess I need to redo this join at a point that's accessible before this floor, before enclosing the new pipe in conduit/ trunking under the floor(?)
4/. I also have central heating pipes in the floorboard void. I guess these should be plastic/ copper, no joins, in conduit. Are they usually at screed level?
Any help gratefully received! Thanks.
