Consisting mainly of clay, sand and possibly straw, they are a 100% renewable product and contain no harmful substances. Compared to other wall coverings, they are less toxic and energy-intensive, as little energy is required in extraction, production and processing, making them attractive to environmentally conscious people.
This thermal flywheel effect makes massive earth walls ideal for mild or hot and dry climates. Clay or sand also have excellent heat retention characteristics and, when properly insulated from the home's exterior, can serve as thermal mass in a passive solar building design in cool climates, keeping interior temperatures stable year-round.
Soils with low clay content, or with no more than 15% non-expansive clay, are suitable for stabilized earth. [20] The clay percentage may be reduced by adding sand, if available. [ 21 ] If there is more than 15% clay it may take more than 10% cement to stabilize the soil, which adds to the cost. [ 20 ]

A compressed earth block (CEB), also known as a pressed earth block or a compressed soil block, is a building material made primarily from an appropriate mix of fairly dry inorganic subsoil, non-expansive clay, sand, and aggregate. Forming compressed earth blocks requires dampening, mechanically pressing at high pressure, and then drying the ...
