Masonry wall construction

Masonry walls of various sorts are utilized in building construction. Masonry walls are the most enduring feature of any structure or building. It separates a structure from the outside world. In masonry construction, the common masonry materials used are building stone, brick, cast stone, glass block, and concrete block. Masonry construction is a type of construction that has the highest durability.
