[Cob] dry stacking urbanite for a bench stemwallMarlin Nissen marlin_nissen at yahoo.comFri Sep 1 09:42:09 CDT 2006
Hi all, I'd really think about mortar for the foundation wall that I was going to pour SO much effort into (Cob is a big undertaking and could last FOREVER with a good foundation and roof...) We used Roman Concrete on one of our projects (lime/sand/burnt clay) and it worked great, but requires time to setup....the other city project (unfortunately) required portland cement mortar due to the quick turnaround and impending frost... my 1 1/2 cents.

I've dug a 3 ft pit and filled it with tamped gravel for drainage and now I'm about to dry stack a bunch of urbanite I've gotten a hold of about a foot up before starting with the cob. The urbanite in question is this heavy-on-the-rocks concrete that had been poured into molds to give the appearance of variously shaped flattish stones. They were a friend's patio that she came to dislike and I took them off her hands for my bench. They are not totally flat. If I place one on the sidewalk and rock it back and forth, it wiggles around because of all the rocks in it. My question to you, fellow cob-listers, is: How do I put down level courses of this stuff? Is there a trick to it or is it as tedious as my initial thoughts on the matter would have it (meticulously adding tiny amounts of gravel beneath each individual piece as it is layed down and checking it's level to the "stones" around it)? A friend suggested that I put cob between the courses as mortar to help level it all out and that the drainage of my rubble trench should keep it all safe. I'm not so sure because it snows a helluva lot around here. Any advice is much appreciated. If you have been in a similar situation, let me know and I'd love to talk to someone on the phone about it.
