| Jul 12 at 21:56 | comment | added | Spehro 'speff' Pefhany | I'd be really worried about electrolytic activity even if the leakage current is acceptable. Liquid concrete is a dangerously strong caustic (similar pH to drain cleaner) and I'm sure a bunch of ions are left hanging around waiting for some moisture. AFAIK, SOP is to use thick PVC conduits. | |

| Jul 12 at 20:32 | comment | added | sirbrialliance | I guess the way I worded it is technically wrong. Resistance of about 1MΩ, conductivity of about 1μS. | |
