Essential Rammed Earth Construction: The Complete Step-by-Step Guide by Tim J. Krahn

Everything you need to know to build with rammed earth in warm and cold climates.

Rammed earth - sand, gravel, and clay or lime/cement binder packed into forms - is a low-energy, high-performance building method, yielding beautiful, sustainable results. It's thermally stable and can be insulated, can actively modulate humidity, provides a healthy indoor environment, and allows site materials to be used for major structural and building envelope elements.

Essential Rammed Earth Construction covers design, building science, tools, and step-by-step building methods for any climate, with a special emphasis on building in cold climates of the northern US, Canada, and northern Europe. Coverage includes:

• Overview of earthen building
• Appropriate use of rammed earth walls
• Stabilized versus raw rammed earth
• Design considerations, including structural, insulation, and building envelope details
• Special considerations for cold and freeze-thaw climates
• Construction drawings, with step-by-step building instructions
• Tools and labor covering industrial methods, low-tech techniques, formwork options, mix design, budgets, and schedules
• Codes, inspections, and permits.

This guide is an essential resource for experienced builders, DIY home owners, designers, engineers, and architects interested in learning about rammed earth construction.
