[Artemisia] "urbanite" construction experience?

[Allen Hall]

Greetings All,

I was wondering if anyone on the list here has experience doing construction 
projects with "urbanite".

For those that don't know what "urbanite" is.... the substance is more 
commonly known as broken up concrete sidewalk and driveways.  Very common in 
urban area dumps.

My understanding is that Duke Guy from Caid has been building a castle from 
this substance and has made good progress.

So I'm wondering if any of you list lurkers knows anything about it.  Never 
know when you'll need ALOT of material for a wall at little to no cost.  No 
cost except for much labor.

YIS,  Alan
