In 1966 Edward T. Dicker hit upon what appeared to be the answer to a problem he'd pondered for years. The builder from Dallas, Texas, had been trying to devise a way to build truly low-cost houses of concrete. Dicker set out immediately to develop his concept- one so simple that he sometimes wonders why nobody thought of it years before. He filled some burlap sacks with cement, sand, and gravel. He wet them, and let them set. Sure enough, he found, they could be used to build concrete houses, apartments, or almost any other kind of structure. In this new process forty pounds of pre-batched portland cement mix are loaded into burlap bags measuring, when filled, 24 inches in length. The bags and the contents are dipped for 10 seconds in a tub of water. Then the bags, with open top folded over, are laid in brick-like fashion to form the wall of the structure. The bags are tied together with 10 inch steel rods. When the stacked wall is completed but still wet, cracks and junctures are filled and covered with a new layer of mortar, applied with a high-pressure gun. This is followed up with a layer of plaster providing a wall of 7 to 8 inches. Dicker points out these advantages: the process minimizes the requirement for expensive lumber; it enables the builder to provide a substantial house at a cost considerably lower than houses built using conventional procedures; it provides a solid masonry building without the expense and time or erecting forms; it requires no skilled labor; it offers an answer to the current demand for quality low-cost housing; it permits generous and economical use of curves and free-form construction; and it provides a building that is virtually fireproof.
