[QUOTE="Sharpend, post: 487147, member: 17152"] You’d be ok with 4” probably only need 3” screed over the top, it will be plenty. If you use copper pipe it has to be lagged with the correct insulation as the cement will react to the copper and corrode it pretty quick, I had this happen in a bungalow I lived in which was about 6yrs old when pipe leaked under floor due to poor lagging. With copper pipe you also have to be aware of heat transfer. The concrete will not crush the plastic pipe, at work the floors are laid with a 3” concrete screed directly over plastic conduit without any ill effects. [/QUOTE]
