I'm Peter Reinhart! Ask Me Anything! Monday, February 15, 2016 7:00-8:00 pm EST

To kick off our AMA feature, we have invited author, chef and master bread maker and host of Pizza Quest, Peter Reinhart, to be our first host! Peter will be in the Forum on Monday, February 15th, from 7:00 - 8:00 pm EST. If you are unable to be online during the live session, you can post your questions in the sticky post. Peter will answer those questions during the live session on February 15th. You can view Peter's answers to your questions as well as what happened during the live session in the session thread.

Ask Me Anything New Forum Feature

You will notice a new forum at the top of the main page called, "Ask Me Anything". This forum will be used for live one hour "Ask Me Anything" (AMA) sessions hosted by people who are knowledgeable in different areas pertaining to wood fired ovens. How it works:
- Each AMA will have a "sticky" thread where the community can post questions they would like answered during the live session. This will allow everyone to participate even if you can't be online for the live session. These questions will not be answered by the host until the live AMA; if you need an answer quickly, you should post it in the appropriate Forum area for the community to respond.
- Another thread will be posted for the live AMA. Registered users who are logged in during the live session can interact with the host by asking questions and receiving responses.
- The live thread will remain in the AMA forum to view after the session.

We hope you enjoy this new feature! Please let us know if there is a topic that you'd like to have as an AMA and we'll look for a host!

  • Foundation question

    I'm getting ready to begin installing a Casa110 on my backyard patio. The patio is made of large slabs of stone and the edges are done in brick. I'm planning to orient the oven over one of the corners of the patio so the front half of the oven will be over the patio and the back half will be over the yard.

    My question is, do I need to remove the part of the patio on which the oven will sit and pour a slab for the whole structure or can I just add a slab extending out into the yard for the back half of the structure?

    Clearly it would be easier to do the latter but the concern is the new slab may separate from the patio and/or the patio structure will not be strong enough for the weight of the oven. Any thoughts would be most appreciated!

    IMHO having a foundation bisected with such a distinct line of support is simply asking for problems. If it were mine I would cut out the area of the patio stones and then work to get the subsoil there and the area outside the patio the same compaction, then pour a base and start my build.

    Hope this helps,

      What he said, for certain.

        I agree. Pour a slab that is separated from your patio. Always expect some settlement, even on well compacted subbase. If the slab is separate, the settlement won't even be noticed. If it is attached or overlapping, there will be cracks.

            It's way too much work to do half right.

              Hi jbuildarkansas

              The patio is made of large slabs of stone and the edges are done in brick. I'm planning to orient the oven over one of the corners of the patio so the front half of the oven will be over the patio and the back half will be over the yard.
              I would get a diamond saw blade, cut through the stone paving across the front of your proposed oven foundation and then (obviously depending on the thickness of your cement and stone paving) dig my footings to have a reinforced beam foundation and drill into the side of the stone and brick and drive some reinforcing steel rod to tie your new footings to your existing paving. If your paving is fairly thin, then I would dig say 6 to 8 " under your cut edge and make sure that the poured concrete is pushed right in and under to ensure that they not only bond but support your paving. You will also need to wash with water the underside of your paving.

              Prevention is better than cure, - do it right the first time!
