If PVC cable is unsuitable for this - why is it suitable for direct bury in
roughging when used on blockwork walls ?? it's the same material in
contact ?


Hmmm... come to think of it, what the OSG probably means is not to lay
cable and then pour concrete all over it. It is possible that something
in the unset/setting mix will react with the PVC. I really don't know,
and someone else here can probably advise better. When putting cable in
channel, the stuff is already set and so presumably more-or-less inert?
They're not worried about wet plaster - good job too!

Hwyl!
