Earth Building Techniques
Explore a variety of earth building techniques, each with its unique characteristics, benefits, and applications. Find the perfect method for your sustainable building project.
Cob Building
Cob is an ancient building material made from subsoil, water, fibrous organic material (typically straw), and sometimes lime.
Adobe Construction
Adobe involves making sun-dried bricks from a mixture of earth (sand, silt, clay) and organic fibers.
Rammed Earth
Rammed earth walls are constructed by ramming a mixture of selected aggregates, including gravel, sand, silt and a small amount of clay, into place between flat panels called formwork.
Straw Bale Construction
Uses bales of straw as structural elements or insulation, typically rendered with earth or lime plasters.
Light Straw-Clay
A mixture of clay slip and straw used as non-load-bearing insulation infill in framed structures.
Earthbag Construction
Uses polypropylene or burlap bags filled with earth (or sometimes insulation) stacked and tamped to form walls.
Compressed Earth Block (CEB)
Machine-pressed blocks made from slightly moistened earth, often stabilized, offering uniform size and density.
Wattle and Daub
An ancient technique using woven branches (wattle) plastered with an earth-based mix (daub).
Hybrid Systems
Combining two or more earth building techniques, or earth techniques with conventional building methods, to leverage their respective strengths.
Papercrete
A lightweight building material made from recycled paper pulp and cement, often molded into blocks or used as a monolithic fill.
Hempcrete
A bio-composite material made from the woody core of the hemp plant (hurds) mixed with a lime-based binder and water.
Underground / Earth-Sheltered
Homes built partially or entirely underground, utilizing the stable temperature of the earth for thermal regulation.
Fairy Chimney Dwellings
Ancient homes carved directly into naturally formed volcanic rock pillars, found notably in Cappadocia, Turkey.
