swarm-list Mailing List: Extraction in Oakland/Emeryville from double-sided brick wall that's the side of a building - Stanford and San Pablo

The pointing seems to be in poor condition, so a cone trap-out will 
require a lot of plugging of holes before the cone becomes effective.
Bricks outside, bricks inside with about 2 inches of dead space in between.
Removing DRYWALL is NOT an option, apparently.  Deconstructing brickwork 
doesn't sound attractive either.
They may give a weak heat signature, or maybe none at all through the 
bricks.
Not sure how long they've been there.  If it's 2 planes of comb thick by 
many square yards, it sounds like a challenge.

Gnarly.
