The following pictures give an idea of the construction process of the domed roof of my room. It is made with the technique explained before in the post: “Dome made with unfired earth bricks”. The difference here is that the roof is over an irregular shape and partly lies over another smaller dome. The shape is easier to understand by looking at the following pictures and the explanations.
The picture below shows the location of the room in relation to the house. The room is in a rounded corner of the house, its ground level is one meter over the the outside level. That elevates the house and isolates it from the ground humidity. All the sandbags that form the lower part of the outside wall will be removed and stuccoed in its due time.
The following three pictures show how the bricks are placed. Only mud is used. The bricks form an arch, the mud to place the bricks is rather liquid, the bricks have a certain proportion and are dry when placed. If not all the conditions above are met the brick or roof (if arches are not formed) could fall.
Below you can see that the left side of the roof lies over a dome. A dome that will probably be a bathroom. I am standing more than a meter above the ground level of the room while a place the bricks.
I stand over some pieces of wood in order to have enough altitude to place the bricks. Some steel rods were temporarily placed over the dome in order to give an idea of the direction of the roof. They confused and annoyed me more than helped so I took them out, they are not necessary.
My head can be seen popping out. As you can see the left side of the roof is not a straight line, it curves to the inside so the dome obtained has an interesting form.
Here are the bricks used. The dimension in centimeters is 20x10x5. They are made of earth, with mud. An earth that I estimate has around 30 % of clay.
Here you can see how the sides of the roof are coming together in order to close themselves. It is interesting to see the bricks forming arches everywhere, strategically integrated, to make a roof. It shows that basically any form can be closed using that technique. Note that each side is formed by arches and the superposition of all sides forms the dome. You can also here see that the right side is curved to the outside. It is clear in this picture how one side of the roof lies over a smaller dome.
Here again you can see how several arches are forming the roof.
