Plywood Slab on Grade – GreenBuildingAdvisor

Clemkonan,

Unfortunately there are no prescriptive paths to getting a rammed-earth house approved in Ontario – meaning you have to get the structure engineered. The second big impediment is meeting the building code requirements for insulation. Most of the resources for how to build these structures comes from warmer climates where they are more common, so take much the advice you find with a grain of salt. I don’t mean to be discouraging, but thought it made sense to lay out the obstacles you will face.

I don’t see any reason why the designs that have been featured on GBA for concrete-free slabs wouldn’t work with rammed earth.
