Jair Dias sent the following pictures and explanation of the cordwood (cobwood) home he is building in Brazil:    “Jair Dias lives in the State of Rio Grande do Sul, Brazil .”

The wood he is using for the cordwood infill is  Pinus Elliottii  (Pine).  The cob mortar is a mixture of red soil (sifted) and combined with clay, sand, sawdust, cement and lime. He says it works very well.  The bottle bricks in a circular pattern are very colorful. Jair Dias Brazil cob mortar 9 with logo

Note the metal roof, the large overhangs and the wrap around porch.   These help to keep the rain off the cobwood walls and stop any degradation.  Jair Dias Brazil cob mortar 8 with logoJair Dias Brazil cob mortar 7 with logoJair is making an outline (in relief) in the mortar so the wood stands away from the mortar. That makes it easy to clean and sand.   I believe Jair means he is tuckpointing the log 3/4″ back from the end of the log.  This will allow for a final coat of cob for the wall.

The bottle bricks are very attractive. Jair Dias Brazil cob mortar 4 with logoThe center does not require a “center post” but rather a modified compression ring that helps maintain the integrity of the roof rafters. Jair Dias Brazil cob mortar 3 with logo

The walls are 12″ thick and made of pine.  Jair Dias 17Lots of windows and entranceways to make the jungle readily available for viewing. I will post more as Jair sends more information.   For pictures of the finished home click on https://cordwoodconstruction.org/cordwood-in-brazil-2
