Bricklaying is the process of arranging and cementing bricks together to create walls, structures, or pavements. It is a skilled trade that requires knowledge of brick types, mortar mixes, and construction techniques. Bricklayers use various tools such as trowels, levels, and jointers to ensure the bricks are laid accurately and securely. They must also have an understanding of building codes and blueprints to follow construction plans. Bricklaying is commonly used in residential, commercial, and industrial construction projects.
