[Cob] Well it seemed like a good foundation...Peter Kaulback peter at thesilverwheel.ca

I built my cob oven in a 24 inch deep hole filled with gravel and crushed cinder block with the walls of my base made from old cinder blocks with the middle filled with more gravel and crushed cinder block and topped off with a 10 inch deep mix of sand and vermiculite. The land here is very high in clay, something like 90% and if it weren't for top soil we would grow bricks instead of crops :) So aside from using machinery to dig further, 24" was fine. I've dug 24" here before and when it rains the water stays in the dug hole and doesn't drain away. Now the sand under my oven floor has shifted and fallen due to the drought this past year, there are still cracks in the field that are 2-3 inches wide and several feet deep. As well there is one crack near my oven at the back of it which I suspect caused my problems. Now I have been able to fill the new cave ins under my deck but I wonder what I could do in the future to prevent or lessen the impact of such natural occurrences? Peter Kaulback
