Earthbag – Roof: Wood & Cob

The roof on top of the large room is made of wood planks that have been charred in place.

With the planks in place we started cobbing around the edge of the roof.

In the smaller room we were still on a journey to see if we could make acacia logs work as a cover.  It was not an easy task, I found it to be frustrating … you can see in the background of the picture above that we were still working on that puzzle. But eventually we figured it out (after I surrendered and let Iulia make and own some of the decisions).

We were not able to get a uniform height, and as you can see below there were some gaps which were larger than we would have wanted.

We also placed acacia beams over the entrance … and in this picture you can see all three parts of the roof in place.

… and for quite a few days now we’ve been cobbing and cobbing and cobbing. First we finished the entire edge of the roof and have now started covering and sealing the entire surface.

There isn’t much to show in terms of pictures because cobbing is repetitive work. Also, the structure is usually covered in tarps and we only uncover the area we are working on … and usually at the end of a session when we are tired and muddy we are not inclined to take pictures.

Below you can see the last of acacia logs from the small room getting swallowed by the cob surface. It took almost 12 batches of cob (a batch starts as a wheelbarrow of dry material).

The small room is now in complete and cool darkness  – it works!

The other roof sections (the large room with the planks and the entrance) should be easier and quicker work. We hope to finish that in the coming days and then the burial of the entire structure … finally protecting (most of) it from the elements.
