Cob: foundations/cob

[Ocean]

Hey, Kiko and I are currently building a garden wall on a poured concrete
footing, with the help of several volunteers.

We coated the top surface with "Redi-Coat", a water-based (!) asphalt
emulsion, to provide a moisture break to prevent the concrete from wicking
moisture into the cob.  We also textured the top of the foundation before
the concrete set, just making bumpy peaks and depressions on the surface.

If you're ever in Corvallis (Oregon) be sure to stop by and see the wall,
it's beautiful!  Oh yeah, it's on 99W (South Third) right next door to the
First Alternative Coop.
