Mud walls are structures made from a mixture of clay, sand, and water, which is shaped and dried to create a solid barrier. These walls are often used in traditional building techniques, especially in regions where these natural materials are readily available. They provide good insulation and are environmentally friendly. In many cultures, mud walls are a common feature of homes, particularly in rural areas. They are often reinforced with straw or other organic materials to enhance strength and durability. Mud walls can also be easily repaired and maintained, making them a sustainable choice for construction.
