Interlocking Compressed Earth Blocks
Interlocking Compressed Earth Blocks (ICEB) are made from laterite soil and cement compressed using a Cinva-Ram type manual press. They are a popular building material in Southeast Asia due to their low cost, accessibility, and pleasing appearance. These blocks are used to make load-bearing walls, eliminating the necessity of pillars and steel reinforcement (unless in an earthquake zone) for support. The interlocking blocks have a male and female component, so they can be laid without mortar, kind of like Lego blocks. The blocks are strong and durable, supporting buildings of two to three stories and lasting over 400 years with a proper foundation and roof overhead. Buildings constructed with the blocks are aesthetically pleasing, and the blocks are thick enough to provide thermal and sound insulation. These blocks are a more sustainable technology than other construction materials of similar purpose. They are made of soil, an easily accessible material, and their use cuts down on the amount of concrete and steel necessary for building construction. Furthermore, they’re an alternative to wood as a building material and fired bricks, which require log burning in their creation. Due to their low cost, these blocks are especially appealing to low-income households in constructing a home. The factory at the CVBT carries a large stock of these blocks to be purchased. More importantly, the CVBT offers training and equipment so that you can transfer this technology somewhere else for local production. Please refer to the equipment and training tabs to learn more.
