Hi:

A fellow I know has a relatively new home (3 year old?) with a poured
foundation. The exterior walls of the un-finished part of the basement are
covered with some kind of "foil" covered product that seems to be held in
place with a little glue here and there and one or two "concrete nails" with
backer.

He wants to extend some outlets. While there is exposed & accessible romex
in the basement it's likely the electrical inspection was done before the
drywall was installed and the inspector ASSumed that the wood studs would be
covered with drywall. Some were and some weren't.

Anyway, he wants to extend some outlets to areas where thee is this "foil"
stuff.

What's the best approach?

1) Put the outlets and surface wiring on top of the "foil" or

Sounds like the best choice.


2) Put the outlets and wiring under the foil and cut out access to the
outlets.


Best not to break the barrier already there. Why create another job?


In the case of #1, we would use metal boxes and metal conduit.

No need for metal conduit for inside-wall conduit. Plastic is much
easier to work, less $ too.


Or should something else be done?

Thanks



For concrete/brick walls you may need surface mount conduit and boxes.
The surface mount is an option on top of drywall that is already
there, but in-the-wall is a much cleaner look.
