Outlandish indeed! :D
Do they still make speed? That might explain things. :D
 
Re: Which are you being required to do ????

Its going to become interesting when the practice of taking the rebar out of the slabs for gec connections, in turn causes spalding to occur and cracking of the slabs becomes the result. Great way for subterranian termites to enter the building.

Instead of burying the copper, why not connect to the metallic water pipe directly from the CCE? What's not concrete encased would be buried, and the supplementation (good word, I know) of the water pipe electrode would be permanently guaranteed.

This would definutely need to be inspected before pour/backfill, but it would kill two birds with one stone.

On the rough, you'd just run your GEC to the water pipe as usual. No ground rods.

What is spalding? Does it only occur outdoors? Our CCE's are generally stubbed up inside the garage, out of the weather.

As Larry pointed out it is spalling and here are some examples.

No but I think moisture is always the root cause
 
Re: Which are you being required to do ????

Bob, that is correct, moisture is involved with most spalling, but rebar placed too close to the edge of the slab or puncture of the slab surface is also at the root of the problem. If the rebar is deep enough in the pour, 1-1/2 inches or greater, there is less chance of moisture getting to the rebar and starting the rust expansion problem. Inside the garage should be ok, as long as it is kept dry. The best way would be to come out the top of the curbing and stay inside a wall partition. From my experience it only takes a slight amount of repeated moisture to start the process.

That would be fine with Cu pipe but it doesn`t hold up well down this area.Most plumbers use cpvc.
