Masonry is the building of structures from individual units laid in and bound together by mortar. The term "masonry" can also refer to the units themselves.
The common materials of masonry construction are brick, stone such as marble, granite, travertine, limestone; concrete block, glass block, and tile. Masonry is generally a highly durable form of construction.
Masonry is commonly used for the walls of buildings, retaining walls and monuments. Brick is the most common type of masonry. Concrete block masonry is rapidly gaining in popularity as a comparable material.
