Traditional Warichchi wattle-and-daub earth construction: termite mound clay and cow dung binders?

Constructing durable Warichchi earth walls requires balanced composite soil formulation. The timber framework is woven from split bamboo and rot-resistant Palu stakes. The daub plaster combines 50% clay subsoil, 30% coarse sand, and 20% crushed abandoned termite mound earth (which contains natural insect salivary enzymes that resist water penetration). Chopped paddy straw (Dahayya) and fresh cattle dung are trodden into the slurry by foot with water. Straw fibers act as tensile micro-reinforcement against drying shrinkage cracks, while cow dung provides bactericidal organic binders that cure into a smooth, breathable wall.
