Available in the United States under the Durisol trademark, this technology is a permanent wall formed from compressed wood chips and cement. The material can be engineered for both above-grade and below-grade use, achieving R-values as high as R-39 above ground and R-17 below ground. The material is ¼ the weight of concrete, can be cut with an handsaw, and has full code approval. It has one of the highest acoustical values, fire ratings, and earthquake ratings of any commercial available material in the United States.
Of
all innovative natural building materials, the Durisol system has been
the easiest to adapt to conventional building skills. It’s also been the
easiest to finance—with construction savings of up to 20 percent in time
and 10 percent in overall wall construction costs. 
This
readily-available technology is completely natural, consisting
of earth compressed under extreme pressure into solid blocks.
These blocks possess high structural strength, massive thermal
storage and an ultra-high acoustical rating. They have a high
natural resistance to rodents, insects, and fungus, and can
be stacked in double rows for increased insulation value.
