How to make a brick tandoor with your own hands – step by step instructions

Recommendation points



Tandoor is the oldest oven on earth, which is still used by many peoples to this day, using it to prepare their national dishes. The simplicity of its construction and functionality is amazing. Therefore, if you want to make a tandoor with your own hands, our master class will help you with this..

Preparation for work, necessary materials and tools

To build a tandoor, you will need the following consumables:

Fiberglass reinforcement Ø 6 mm15 m3
Steel wire O 3 mm (the main requirement for it is that it should bend easily when twisting is formed)15 m5.8

To work, you need the following tool:

  • a container for mixing building mixtures (concrete, mortar, facing mixture);
  • plastering rule;
  • spatula (width 12 cm);
  • painting brush (width 10 cm);
  • grinder with cutting diamond wheel for ceramics.

Making a foundation for a tandoor

Despite the fact that the tandoor is a light stove structure, it will be installed in the open air, therefore, a solid foundation is needed for it.

First, determine the type of soil, if you have heaving, heavy (clay, loamy or low-lying) soils, then a reinforced foundation must be cast on them. The columnar foundation will allow to solve this problem. If the soil is light (sandy loam, sand or soddy podzolic), then you can simply cast a monolithic concrete slab.

The base of a standard tandoor is 100×100 cm, the thickness of a monolithic foundation slab for such a structure is 10 cm enough. Along its perimeter we select soil to a depth of 15 cm, at the corners of the slab we make recesses with a drill to a depth of at least 70 cm and a diameter of 12-15 cm.

We reinforce the resulting holes (as a reinforcing rod, we recommend fiberglass reinforcement with a diameter of 6 mm, connected by a quadrangle), and fill it with concrete. Concrete is prepared in a ratio of 3: 1: 1 – one part of gravel is taken into three parts of sand (with a fraction of no more than 1 cm in diameter) and one part of cement grade not lower than PC 400. The consistency of the batch should resemble thick sour cream (in a more liquid form, porous formations are formed , and a thicker one will not fill all the voids).

We fill in the recesses 5 cm above the level of the bottom of the pit. This can be done using formwork 5 cm high, laid on the bottom. For the simplicity of the formwork device, you can use a container strip by rolling it into a ring or any similar material.

After that, we pour sand on the bottom of the pit, which will play the role of a damper pillow. The height of the sand layer should not be higher than the recessed formwork. Then we pour the sand abundantly with water so that there are no caverns in it, and on top we lay the formwork for a monolithic slab.

As a formwork, we can use a 15 cm wide edged roof board (10 cm in the ground and 5 above the ground). We put a reinforcing mesh on the sand pillow (ideally if you fix it 5 cm from the level of the sand pillow). Be sure to level everything with a level and then fill it with concrete.

Concrete sets for at least 72 hours, during this time we will prepare a rule and bricks of a certain shape.

Tandoor base laying

We will use refractory (fireclay) brick as the main building material for the tandoor. It is dense enough not to adsorb moisture on itself at the time of temperature changes, and, as a result, practically does not collapse under the influence of seasonal temperature fluctuations.

The base of the tandoor is a circle, to form it, we outline a circle along the pattern (diameter 75 cm). Then we lay out the bricks, numbering them in order so as not to get confused, and with the help of a cutting wheel we carefully cut off everything unnecessary from each brick.

We put roofing material on a concrete base for waterproofing from groundwater.

As a joint solution, we use a refractory kiln mixture for fireclay bricks (sold in any specialized store). The usual clay-sand mixture cannot be used, because it:

  • quickly cracks due to temperature changes;
  • does not form a rigid bond with fireclay bricks.

Mix the mixture thoroughly and then apply it to the roofing material with a spatula. On top of the mixture we lay out the clippings of bricks, according to their numbering.

Making a “rule” for a tandoor

Now we make a rule for laying walls, as indicated in the photo above. According to tradition, the width of the base of the tandoor should be equal to its height, while the neck should be 1/3 less than the base.

Therefore, we collect the rule of the following sizes:

  • pole height – 1 m;
  • base length 30 cm, second level 25 cm and third level 20 cm;
  • the step between the guides is 25 cm;
  • a piece of plywood was used as a template for a vertical wall (you can use a lamella from a bed on which a mattress is placed).

We raise the walls of the tandoor

All bricks are stacked upright. Therefore, the strength of the first row installation is very important for the entire operation.

We put the bricks on the base of the tandoor, put the inner edge close to each other, and coat the seam with mortar.

After the first row is laid out, we pull it together with steel wire. We twist its ends and hide it in the seam between the bricks (the wire will remain on the tandoor).

We lay out the second row in the same way. However, starting from the second row, the bricks will have to be cut (after one) to a wedge.

At the same time, we also lay the inner end faces as tightly as possible, and carefully coat the outer ones with a solution.

After the third row has been removed, we begin to plaster the tandoor with an oven mixture.

The total layer of plaster on top of the tandoor should be at least 10 mm. Form the upper edge in the form of a roller.

After the layer of the solution has dried (the tandoor at this time should be covered with a cellophane film from the rain and shaded so that it does not dry out from direct sunlight), we cover it with acrylic refractory paint, although in the East it is customary to whitewash the tandoor.

As the solution finally dries out (no earlier than 72 hours), the inner space of the tandoor is cleaned of sagging, dirt, etc. – it is best to do this with a hard broom.

The tandoor is ready. You can fry tortillas and treat guests.
