Introduction to Alternative Roof Systems Without Bond Beams

Traditional earthen architecture was built without concrete, steel, or fossil fuel products. We feel that, in most cases, concrete and heavy wood bond beams are an unnecessary use of money and resources. (If you are considering building a roof system onto an earthbag structure without a continuous bond beam, please review Chapter 5). As a review, and to prepare for building a roof without a bond beam, these structural features should be taken into account.

We would not advise putting a heavy compression style roof on earthbag walls without a concrete or wood bond beam. (Domes are a separate category, presented in Chapter 11).

All of these roof systems direct the weight of the roof straight down onto the walls. When we've met all the structural safety features we're ready to put up our roof (see Fig. 9.10 on following page).
