Dome Installation Video - Casa / Premio / Modena


For many of you who bought a modular oven, you may have asked how we put the domes together when we build them. For those of you considering one of our ovens, we shot a video to make your install easier.

Check it out on our You Tube Channel.

  • Waterproofing the vermiculite slab

    Hi folks,

    The dome is complete and enclosed with backer board. I am hoping to get the outer facade done before the North Idaho winter hits. However, I won't get the counter-tops done before the snow falls. So this leads to a question regarding the vermiculite slab.

    The vermiculite slab extends beyond the base of the dome and as such, wicks water into the floor of the oven. Once I get a counter top on, this will be fine. Is there a temporary way of waterproofing this so as to keep it a bit drier (that can later be covered with thinset?).

    Thanks for all your assistance through this project. I have not laid bricks in 35 years and - without this forum - I don't think I would have tried this! For anyone interested in the project, my better half has been documenting the project stages on Google's Picasa.

    Good Roads

    "The vermiculite slab extends beyond the base of the dome and as such,"

    Tarp it over. Any thinset or render will crack at the juncture anyway.
