 Wattle and daub has been used for at least 6,000 years, and is still an important construction material in many parts of the world.This process is similar to modern lath and plaster, a common building material for wall and ceiling surfaces, in which a series of nailed wooden strips are covered with plaster smoothed into a flat surface.Many historic buildings include wattle and daub construction, and the technique is becoming popular again in more developed areas as a low-impact sustainable building technique.
