Brickwork is a masonry construction technique in which bricks are laid in patterns to form walls, foundations, and other structures. Brickwork is typically made from fired clay bricks, although other materials, such as glass and concrete blocks, can also be used. The bricks are bonded together with a mortar, which is made from a mixture of cement, sand, and water. Brickwork can be used for a variety of structures, such as interior and exterior walls, fireplaces and chimneys, and can be used in both residential and commercial buildings.
