Compressed stabilized earth blocks (CSEBs) are comparatively new earth-based materials similar to rammed earth, adobe, and bricks. Common stabilizers used for CSEB production are cement and lime. Lime is more environmentally friendly than cement. (Hint: “S” stands for stabilized!)

A compressed earth block, 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. (Wikipedia)

CSEBs are:

• Non-toxic
• Fireproof
• Energy efficient
• Even bullet-proof
