DIY Project Details:

It’s important to remember that an outdoor oven will need a strong foundation and that skimping on concrete when constructing the base might mean foundational cracks due to weather fluctuation, or even the structure of the base being compromised due to insufficient mortar.

 Rebar is also a great addition to a foundation, extending its life and mitigating cracks.

Laying the foundation, When it’s finally time to break ground, dig out a base for your foundation.

The depth of the pit will vary depending on the kind of soil that your home sits on; in general, a looser soil composition (like those of clay, peat, and sand) will require more depth.

DIY Project Details:

Once your pit is dug, make sure it’s squared off on its corners, and then lay down a shallow layer of gravel on the bottom.

 If you’re building with rebar, this is where the grid would come in; if not, then just pour your concrete mix in and level it off at the top of the pit with a spirit level and a long, straight piece of wood.

Let this foundation cure for at least 72 hours.

Building to height, After the foundation is cured, it’s time to start building up!

When constructing the base itself, make sure to pay close attention to the width of each side, ensuring it is following your original plan and not expanding or shrinking as you add masonry.

DIY Project Details:

Using small amounts of concrete as a mortar, join the masonry together at important stress points, seams, and edges.

It’s up to you if you’d like to include more or less mortar for aesthetic purposes, but make sure that the amount used is sufficient to glue the brick together.

Bear in mind also that the weight of your oven dome may necessitate using stronger material or more mortar. Leave the front empty for now.

The final height of the base can also be adjusted, typically according to the primary chef’s own height.

 Bases between 40″ – 45″ usually keep the oven’s door at a good height.

First do a dry installation of the unit, including the arch. Center the oven on the slab making an outline of the oven with pencil or chalk. Remove the oven elements.

 Open the bucket of refractory grout. Save the water on top of it by pouring it into another container.

DIY Project Details:

Transfer the grout into a larger container for easy mixing (a trough or a 5-gallon bucket should do). Slowly add the liquid until the grout is the consistency of creamy peanut butter.

There will be water leftover, save it so that you can pour it back over the remaining grout before you store it.

All the bottom (floor) elements are installed with the smooth side up and should be level because this is your cooking surface.

Start with the small rectangular floor element in front of the oven. Put three individual globs of grout on the underside of each tile, set, and tap the piece level.


 If the tile is not level, then pull it up and add more grout, tapping the tile until level.

Install the other tiles in the same manner. Let the tiles sit for an hour before continuing.

DIY Project Details:

This will allow the tiles firm up thus preventing any accidental shifting. Return the remaining grout to its bucket, adding the extra water that you saved on top, replace the lid and keep in a cool, dry place.

 Put as much grout as you’re comfortable within a pastry bag and grout the tile, grouting only the seams between the tiles.

 The grouted seams should be depressed enough so that when you will run a pizza peel or casserole across the oven floor it will not bump against the grout and possibly chip it.

The dome pieces interlock snugly and need only a minimal amount of grout.

Grout only the female groove on the dome elements with about a 3/8-inch bead of the grout.

Do not grout the dome elements to the floor elements or to the refractory pad.

DIY Project Details:

Start by placing the male dome element (support it) then the female element with the slightly grouted groove.

After the dome elements are set, look inside, you will notice a space all the way around where the floor meets the dome walls.

 Do not fill this space; this space is needed for the expansion of the floor tiles when heated.

 Apply a strip of refractory grout across the outside seams of the dome. Don’t grout the seams inside the oven.

Put a little dab of grout on the bottom and generous amounts on the backside of the arch that touches the oven, set, and hold in place.

You can face the arch with another material such as stone, granite, tile, or brick.
