Mud bricks are building materials made from a mixture of clay, sand, and water, which is shaped into rectangular blocks and then dried in the sun. This ancient construction method has been used for thousands of years, particularly in regions with abundant soil and limited access to timber or stone. Once dried, mud bricks are strong and durable, providing good insulation against heat and cold. They are often used in the construction of homes, walls, and other structures, especially in areas like Mesopotamia and North Africa, where traditional building techniques are still practiced today.
