Re: Closed loop embedded in a concrete wall

["Crash Gordon" <webmaster@xxxxxxxxxxxxxxxxxxxxx>]

I'd put it in conduit.
You really think someone's gonna crack through the basement concrete?

|
| The wire or cable should be mechanically thick enough to last a long
| time (many many years), but readily break if the wall is attacked with
| drilling, sledge hammers, etc.
|
| What materials would be best for concrete?  Would you use a plastic or
| metallic sheath? ...Possibly PVC?
|
| Any suggestions or advice would be greatly appreciated.
