Thanks guys! I love building with bamboo, have done 2 other structires in Colombia using Guadua Agustifolia, this is Dendrocalamus Asper.
We began harvesting monthly for about a year before beginning construction. We dug out a 9 meter pool and dipped them for a a week at a time in mix of borax and boric acid.
We drill through and join with threaded rod.
The experior is
cob on top of a layer of opened bamboo sheets (esterilla) and
chicken wire stapled to that, then the cob. Mixed in a fiber I found near farm in Ecuador called ABACA, a banana type plant that is used to make fabric, canvas, and is a big export. In Colombia the typical fibre used is an agave plant called FIQUE, used for
coffee sacks.
Cheers!
