I drilled a test hole in my boarded floor. It went through what looks like a damp proof membrane and into some polystyrene insulation. I don't think id have much luck pushing a cable through.
The boards are 20mm thick. It's my thinking I could machine out a channel about 7mm deep. Then when my floor is fitted above the load will be spread enough not to worry about. Someone tell me they agree and I'll be happy.
