Moisture Issues:

Clarifying The “Breathing Wall Concept” – a must-read article on air-exchange as it pertains to various earthen wall assemblies, and how the term “breathable” is riddled with misconceptions. Earthen walls are, however, excellent at attenuating short spikes in humidity and, by design, are better able to handle moisture that gets into the wall than a conventional vapour-based assembly.

Podcast

Mike Jones Talks With Dirt Craft About His Straw Bale Home Journey – we worked with Mike Jones and his family on their timber frame straw bale home in Saskatchewan. Dirt Craft ran a number of workshops during the construction of the house, and consulted on recipes for their earthen plaster system, and worked along side Mike and his family & friends to stack bales, prep the walls, and apply plaster. Being located in Saskatchewan, there was ample straw and clay available for their walls, plasters and floors, which made use of these locally available materials and yielded beautiful results.
