I am planning a straw bale house and wanted to bypass the cost of pouring a cement footer for the straw bale walls to go on. Also my build site is on a slight grade so several courses of tires would bring the base of the bales above the dirt line.
I would run two courses of 4x4s with nails nailed half way in every 6 inches on the inside which would then be filled with cement (or possibly a cob mixture), ensuring a solid connection and fastener for the bale walls.
The bale walls will be in-fill not load bearing.
Can you see and problems developing?
Would filling the bottom plate on top of the tires with cob instead of cement be strong enough?
Do you have any ideas on how to attach a bale wall to a tire pony wall?
