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, marble, granite, travertine, limestone, cast stone, concrete block, glass block, stucco, and tile. Masonry is generally a highly durable form of construction. However, the materials used, the quality of the mortar and workmanship, and the pattern in which the units are assembled can significantly affect the durability of the overall masonry construction. Masonry is commonly used for the walls of buildings, retaining walls and buildings.
Brick and concrete block are the most common types of masonry in use in industrialized nations and may be either weight-bearing or a veneer. Concrete blocks, especially those with hollow cores, offer various possibilities in masonry construction. They generally provide great compressive strength, and are best suited to structures with light transverse loading when the cores remain unfilled. Filling some or all of the cores with concrete or concrete with steel reinforcement (typically rebar) offers much greater tensile and lateral strength to structures.
Investigation or land surveying technology, professional, scientific and accurate point angle and the distance between them determines the position of the terrestrial or three-dimensional and generally authorized to practice by surveying the various members of the building profession. This point is common in the earth's surface, they are often the ownership, location (corner of underground features, surface location of the building) or other governmentally required or civil purposes (Real Estate sale) of land on the map and is used to set the boundaries.- Person's name
