Council house cavity obstructions, Caution: Newbie content

[7liasons]

Looking to fit extra sockets and move some light switches, the plasterboard cavities are all lined with a corrugated cardboard.
Advice on how to put in new cables, routing and any special tools
Thanks in advance,

Sounds like you have prefab walls, two layers of plasterboard led apart with a cardboard grid/matrix? With the walls are a lot thinner than normal stud walls, maybe half the thickness?

If so, you can punch through the cardboard with a stout cable rod to get a cable up/down the wall.

thanks for tip, I'm guessing most cable rods would be capable of forcing a role through
