    clipping cables on damp proofed wall

    Got a job rewiring a kitchen where the walls have been damp proofed with a membrane. I have spoken with the plasterer and he is fine studding the wall out so that I can use drywall boxes but unsure of how to clip the cables as the nails will puncture the membrane. Any ideas please?
