Thanks to all those who came out to Watershed Materials' and Rammed Earth Works' Open House on Saturday, February 13th 2016. Over 200 people came out during the course of the event including Bay Area architects, engineers and developers interested in new techniques for sustainable building. We gave demonstrations of our most recent technologies for sustainable building systems with low cement masonry and rammed earth applications including :
