George Nez, developer of fiber reinforced hyperparabolic roof systems

George Nez is a long-time humanitarian and developer of acrylic and fiber reinforcing to build hyperparabolic roofs. Although George is not in this photo, he was instrumental in the September, 2008, technology transfer of this hyperparabolic roof with a space-age mud and wattle membrane to Rwanda. His direct training and assistance in support of the kitchen crew and the trainers who went to Rwanda is the type of humanitarian assistance which leaves lasting new knowledge as well as artifacts.

Ferrocement.com is honoreded to be rewarded by George's reference to its development efforts, "... these bamboo-framed panels resulted from your previous work, and particularly the practical joining.ÊAnd your use of burlap fabric base."

This photo of the assembled panels is reinforced with one layer of muslin or burlap below and then a layer of poultry netting above, it is then covered with acrylic altered cement and sand. Application of several layers leads to an overall thickness of about one centimeter (3/8 - 1/2 inch). The next photo illustrates installation of a George Nez hyperbolic paraboloidal roof system on a school in Afghanastan, it includes picture illustrating how this membrane was made.
