Like the Terracotta Army
Standing like figures from the excavated Chinese Terracotta army, our compressed earth blocks- formed from the very ground around our home- stand ready to be placed into service guarding our interior space from the environmental hazards outside. When faced with foam and stucco, the walls are about a foot thick with an R value of 50. They also provide thermal mass to our house, helping to keep it at a consistent temperature. The top blocks are dark because they were just rained upon. It's good to keep the blocks damp to allow the cement that gets mixed and pressed with the earth to cure.
