The SuperAdobe building system can be used for structural arches, domes and vaults, or conventional rectilinear shapes. The same method can build silos, landscaping elements, or infrastructure like dams, cisterns, roads, bridges, and for stabilizing shorelines and watercourses.
Basic Materials Needed:
- Synthetic, low UV (ultra-violet) resistant degradable sand bags
- Four-point, two strand, galvanized barbed wire
- Soil & Water
The building process is intentionally simple, but the structural integrity of SuperAdobe is the result of years of research. The structural design uses modern engineering concepts like base-isolation and post-tensioning. The long coils of sandbag provide compression (vertical) strength. While the barbed wire adds tensile (horizontal) strength. In addition, the sandbags add flood resistance. The earth itself provides insulation and fire-proofing.
WHY A DOME?
The arch is the strongest form in architecture and has been used in building for thousands of years. A dome is simply an arch rotated 180 degrees. SuperAdobe is extremely well-suited for building arches, domes and vaults, and SuperAdobe domes are extremely strong structures. They have passed California earthquake code tests, and withstood a 7.6 magnitude earthquake in Nepal.
Using geometry and a simple compass tool, builders can easily create corbelled dome structures of various heights and up to 22 feet in diameter.
