A prepared mixture of moistened soil and cement is shoveled into sturdy, two-sided, wooden forms set on a foundation, then compacted layer upon layer to form rock-hard, rammed-earth walls.
PISE walls are easier, faster, and less costly to erect than rammed-earth walls. Here, high-pressure air shoots a prepared mixture of moistened soil and cement against a one-sided form. Reinforcing steel in the wall eliminates the need for supplemental concrete bond beams. Photo by Cynthia Wright
