Wattle and daub

Wattle and daub is a composite building method used to create sturdy walls. A composite method combines different materials to make something stronger.

In this process, builders create a woven lattice of wooden strips called wattle. They then cover this lattice with a sticky material known as daub. This technique has been used for at least 6,000 years. It remains an important construction method in many parts of the world today. Many historic buildings around the globe still feature this traditional craft.

The construction begins with the wattle, which acts as a structural skeleton. Builders weave thin branches or wooden slats between upright stakes. These branches can be whole or split into thinner strips. Different regions use different materials for the wattle. For example, willow has been found at the Mitchell Site in South Dakota. Other builders might use reeds or vines to create the weave.

The wattle can be made as loose panels to fit into timber frames. It can also be made directly on-site to form an entire wall.

Once the wattle is set, the daub is applied to fill the gaps. The daub is a mixture made of three specific categories of ingredients. Binders, such as clay, lime, chalk dust, or limestone dust, hold the mix together. Aggregates like sand, mud, or crushed stone provide bulk and dimensional stability. Finally, reinforcement is added using fibrous materials like straw, hay, or animal hair. This reinforcement helps the mix stay flexible and prevents it from shrinking as it dries. Builders mix these ingredients by hand or by treading on them with feet or livestock.

There are two popular ways to arrange the wattle infill panels. The first style is called close-studding. This method creates very narrow spaces between the timbers, usually between 7 and 16 inches wide. Because the gaps are so small, weavers use horizontal strips called ledgers instead of a tight weave. These ledgers are secured into upright timbers through a system of drilled holes and chiseled grooves. The second style is square paneling. These are larger, wider panels often seen in later timber-frame houses.

To make square panels, builders insert vertical timbers called staves into the frame. These staves are then used as a base to weave flexible horizontal wattles.

This building technique has a very deep history across many continents. It has been used since the Neolithic period by various ancient cultures. In Europe, it was common for the Linear pottery and Rössen cultures. In Western Asia, evidence exists at sites like Çatalhöyük. In Egypt, archaeological sites like Merimda show that wattle and reed was used as early as the 5th millennium BCE. This was used even before the invention of mud bricks.

The method remained popular in Egypt until about 3100 BCE. The Roman writer Vitruvius even recorded its use in Rome.

Many different cultures developed their own unique versions of this method. The Mississippian culture in North America used wattle and daub for their homes. In Brazil, similar techniques were used in South America. The Ashanti people in Africa use it for traditional architecture.

In the United States, French settlers used a version called pierrotage. This involved infilling timber frames with lime mortar and clay mixed with small stones. In Louisiana, they used bousillage, which was a mix of clay and Spanish moss. Even in South Australia, pioneers used "pug and pine," which involved driving native pine into the ground and filling gaps with clay and grass.

While wattle and daub is less common now, it connects directly to modern building. Modern architecture has largely replaced it with brick, mortar, or lath and plaster.

Lath and plaster uses nailed wooden strips covered in smooth plaster. Even more common today is drywall, which uses large plasterboard sheets. Understanding wattle and daub helps us see how humans have always used the Earth's materials to create shelter. It is a foundation for the many ways we build walls today.
