I'm hoping to dig out my solid kitchen floor at the weekend to retrofit insulation and wet ufh. In terms of depths the current guidance seems to be
"Today, new solid floors are more substantial, typically comprising 150mm of compacted hardcore, 50mm of sand, a polythene sheet DPM, 100mm of concrete, then around 100mm of insulation and a 60mm screed."
But I'm not sure what the building regulations are, I'll see what I can agree on with my build control officer
Do I really need 150mm of hardcore and 50mm of sand? I'm thinking 100mm of PIR is good, but would it be worth putting in 150mm or is 100mm more than sufficient? I need to work out the right depth to get to for the material layers whilst I have some helping hands around
