Essential Rammed Earth Construction - (Sustainable Building Essentials) by Tim J Krahn (Paperback)

About the Book

Essential Rammed Earth Construction covers design, building science, tools, and step-by-step building methods for building with rammed earth - and, gravel, and clay or lime/cement binder packed into forms - in any climate with an emphasis on cold climates.

Book Synopsis

Build Strong, Sustainable, and Beautiful Rammed Earth Homes

Part of the Sustainable Building Essentials series, Essential Rammed Earth Construction is the complete step-by-step guide to designing and building durable, high-performance rammed earth structures. Learn how this ancient method creates homes that are naturally comfortable, resilient, and environmentally friendly.

What You'll Learn

• Structurally Strong Walls: Rammed earth walls provide exceptional strength, stability, and longevity with minimal maintenance.


• Sustainable and Low-carbon: Use locally sourced materials and reduce your environmental footprint compared to fired-brick or concrete construction.


• Natural Thermal Regulation: Rammed earth walls store and release heat to naturally stabilize indoor temperatures year-round.


• Durable and Low-maintenance: Fire and pest resistant with a long lifespan, rammed earth offers a practical and aesthetically striking building solution.


• Design and Construction Mastery: Step-by-step guidance on formwork, mix design, compacting, finishing, and cold-climate adaptations.


• Plan, Budget, and Build Confidently: Tools, labor estimates, and code references make projects safer and more efficient for builders, designers, and DIYers.

Written by Tim J. Krahn, P. Eng., a registered professional engineer with decades of experience in natural building, Tim has engineered over twenty rammed-earth projects in Canada, including the first net-zero municipal building in Ontario. His expertise ensures that this guide blends practical construction methods with rigorous building science.

Transform your approach to sustainable construction with practical, science-based strategies that create strong, resilient, energy-efficient, and beautiful homes. With step-by-step visuals, actionable insights, and real-world examples, Essential Rammed Earth Construction equips builders, architects, and DIYers to confidently achieve high-performance results.

Explore the full Sustainable Building Essentials series for comprehensive guidance on foundations, walls, insulation, mechanical systems, finishes, and more--everything you need to create durable, efficient, and sustainable homes.

From the Back Cover

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

A much-needed and science-based update for designers, engineers, and builders.
-- Bruce King, PE. Author, The New Carbon Architecture

Provides excellent background, engineering science, and practical advice for constructing rammed earth structures... and will be especially of interest to those building in colder climes.
-- Charles Augarde, Professor in Civil Engineering, Durham University, UK

A great book for anyone who wants to deepen their technical knowledge of rammed earth wall systems.
-- Clifton Schooley, Clifton Schooley & Associates, Rammed Earth Designers and Builders

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.

This book could well be the cornerstone of a modern boom in the popularity of rammed earth.
-- Stephen Dobson, Ramtec, Western Australia, builder of over 750 rammed earth structures
Great for a client, architect, engineer, and builder.
-- Dr. Paul Jaquin, Structural Engineer, Queenstown, New Zealand
