What kind of wiring are you trying to hide?

If this is wiring inside of walls, it should be inspected by an electrical inspector, then you may cover it with drywall or another approved building product--panels, etc.

If it is a surface wire system maybe conduit can "hide" the wires but the devices will be exposed--switches, lights, etc.

If it is an industrial control panel, lock it. Make sure there is an operable disconnecting means.

What is "best" for one situation may not be the best for another. Why do you not want it copied?

6" of 3500 PSI concrete usually does the trick.

Can you expand on what it is exactly that you're trying to accomplish? I don't believe that I have ever heard a question of this nature.

Tom I like your idea better! But it must be inspected first!!
