The lower floor of my house ( 3 rooms and a hall ) is being concreted to avoid future flood damage.
I have spoken to a few electricians but to date none has any experience of laying a conduit cable guide in a concrete floor.
Reading the various Threads. Putting cables in a plumbers polythene pipe is acceptable but may prove challenging when you need to rewire. If it is layed on the DPM before the concrete is poured it can be dislodged.Laying plastic conduit on top of the concrete base before the insulation goes in would be easier to fit but presumably reduces cooling. The other method of laying the cables in a rectangular plastic conduit with a wooden lid( Manthorpe Building products ) near the surface of the finishing screed around the perimeter of the rooms is rarely discussed. It has the advantage that you can get at it even if it has a covering of screed over it.
Does anyone have any recommendation on which method I should use. I will only get one shot at it.
You knowledge and experience would be greatly appreciated.
