Building an outdoor masonry oven

mooch · Apr 5, 2012

I am going to be starting my wood fired bread oven project. I live in pa. All of my research so far does not have a footer below the frost line even in cold climates. The structure will be approx. 5 x 8 feet built on a slab with 8" block as the base and the oven at working height. Most info says in cold climates to just put 2" insulation under the slab and it will be fine. Do I need to put a footer and foundation below the frost line or is that just total overkill?

thanks

Good Morning, Here is an oven built by my friend John:

With no exterior heat added the insulation under the slab will really do nothing.

Thanks for the links, I have most of my plans. I was just wondering if anybody would put such a structure on a footer below frost line or since it is a relatively small footprint just use a slab.

Are you going Pompeii style or other type?
Here's my build.

As far as the footer goes, I've heard it both ways. I would play it safe myself.

I built one last year, I used a rubble foundation, and then put the insulation down and then poured a pad with rebar on that. The fornobravo forums are great.
