COB clay mixture is developed by mimicking a strong clay surface. It can be used to build houses, make building blocks, or use it on a plaster surface to create curved shapes and corners. Cob mixture is also well suited for renovating clay houses and building clay floors.
COB is a mixture of sand and clay, during the work process we recommend adding straw up to 20 cm long. The mixture is usually mixed on a tarp with barefoot or in a special mixing machine. Cob is a strong building material from which houses can last for thousands of years. The oldest known cob-style house is 10,000 years old.
The word COB comes from an old English word meaning "piece" or "loaf."
