How do I install plug sockets/run cables when installing a cavity drainage membrane system in the basement?

Plug sockets can simply be surface mounted onto the plasterboard, preferably using plastic boxes. Cables, conduits and pipes can be run in the cavity between the Oldroyd Xv cavity drain membrane (http://www.cellars.co.uk/products/cavity-drainage-membrane-oldroyd-xv-clear) and plasterboard. Where needed, the Oldroyd brick plugs can be used to create a sealed fixing point for pipe clips etc.
