Process-driven material

Coconut husk fiber, also called coir, is extracted from the outer husk of coconuts. The material is long-lasting due to its slow degradation process as compared to other natural fibers. It is expected to improve the strength of the rammed earth brick. In addition to the coir, 30% of clay is added to the sandy soil taken from a construction site.
