CSC/AIBC Rammed Earth Site Tour

Thanks for checking in on the status of The Cabin in the Woods, an insulated rammed earth house being built in Sooke BC Canada.

South side of The Cabin in the Woods.

On October 6th we hosted a tour for interested building professionals through the Vancouver Island CSC (Construction Specifications Canada).  AIBC (Architectural Institute of British Columbia) recognised the tour as a learning opportunity and registered professionals received learning units for attending the tour.  There were 20 architects, designers and materials professionals who attended the tour.  A 10 page information booklet was created to give attendees confidence and knowledge in the rammed earth process.  The SIREWALL technical engineering document shown was referenced.

We talked about everything from thermal mass and dynamic or effective R-values to the basics on mix design.  The goal was not to educate everyone how to build their own rammed earth paradise but rather to show them we have this down to a science and that we will build your rammed earth paradise!

Weighing up enough material to fill two forms and two compression cylinders.

As a test of the mix we created and rammed during the tour, we rammed two compression testing cylinders.  These are to be tested by Goal Engineering (attendees of the tour) who generously offered to do so while attending the tour.  Results will be posted when they become available.

A final hands on test was performed by ramming two large blocks.  Most of the tour participants got a chance to get their hands dirty ramming the blocks.  Later on during the tour we stripped one of the hour old rammed earth blocks and scratched, hit, rolled and generally observed how dense the freshly rammed earth matrix can be.

Playing around with one hour old rammed earth.  Its surprisingly strong at an early age.
Thanks to those who attended the site tour, I had a lot of fun showing everyone around.
