The Earth Block
Also known as the Pressed Earth Block or Compressed Soil Block, the Compressed Earth Block is a building material that consists primarily of damp soil compressed at high pressure to form the Earth Block we know. At Earth Block International, we use a mechanical press to form blocks with the perfect mix of sand, clay, silt, water and stabilizer for your climate and elevation. Here, you will learn about the many advantages of Earth Blocks.
Our blocks are so simple, you can count the number of ingredients with one hand. A typical CEB contains sub-soil, clay, silt, water, and a stabilizer, (typically portland or lime.) These ingredients combine to form a perfect block. The clay acts as a binder for the block, while the soil and silt are healthy, non-toxic components. Water is used to maintain some moisture within our block. Lastly, the stabilizer helps support the Earth Block's durability and shape.
Step 1 - Origin of Material
The soil is a sandy clay mix with the correct percentages of each is key to making a suitable block. We use the best mix to make the best blocks.
Step 2 - Screening the Soil
The material is screened on-site to approximately 1/2” which is used for block making. Fine soil is important for the blocks to combine properly.
Step 3 - Loading the Machines
The screened material is loaded into the mixer and 6% +/- stabilizer (lime or cement) and 10% water are added. The hydrated and stabilized soil is then added to the block machine
Step 4 - Block Production
Blocks are ejected from the machine at the rate of anywhere from 100 to 200 per hour. Blocks are then loaded onto pallets which get shipped out for delivery
The finished product is timeless and will last for generations, providing a safe and healthy home. Enjoy!
