The roofing material that you speak of is made in Hosur. There is also a research station somewhere in Bangalore, near Peenya if I remember. The roofing material is made by sandwiching bamboo mats in fibreglass resin. In other words, the glass fibre used for fibreglass is replaced by Bamboo.
You can also build lovely walls with Bamboo and mud. The bamboo is split and beaten flat. Then it is woven in a basket weave. After that, it is plastered with mud inside and outside. It makes for a light, beautiful wall, particularly when it is painted with Chunam. All the houses in villages in the plains of Assam are built like this, and mounted on stilts. They never get spoilt in the floods, if one ensures that the roof overhangs enough to prevent water from splashing on them.
On our museum land in Avani village, Kolar, we have planted clumps of Bamboo. It has taken some time for these clumps to develop, because of the drought. But this year, they might take off. I am looking forward to planting more Bamboo, so that we can harvest it and use it for some of the museum buildings. A combination of traditional bamboo construction techniques and a few modern techniques, can work wonders. It is a wonderful material.
