Volunteers and friends of Origin Brewer, a new nano-brewery in Richmond, California, were led by Contractor Chris Polk and the talented crew of Watershed Materials (Dan, Edward, Gabriel, Khyber, Taj, and David Easton) on October 23rd, 24th & 25th for the raising of the Watershed block walls. The ATA designed brewery was engineered by Anthony Dente of KDSE to minimize the use of portland cement based concrete by utilizing horizontal ladder trusses, so not all of the cores need to be grouted. Watershed Block features around 5% cement content vs. over 10% in typical concrete block.
