Most compressed earth blocks (CEBs) are made in a mechanical press with a mixture of sandy soil, clayey soil, and a small amount of cement and water. CEBs typically require no plaster and are popular for walls, privacy walls, planters and much more. We used CEBs on our outdoor kitchen and raised garden beds. Recently I’ve discovered some rather unusual and very interesting CEBs made with unconventional materials. In addition to the compressed blocks shown here, you could use crushed glass, lava rock, brightly colored soil in sediment-like layers, sea shells, crushed limestone and other low cost and sustainable materials. The main idea is to utilize what is affordable and locally available.
