This includes the installation of brick, concrete block, stone, marble, slate or other units and products common to the masonry industry, including mortar less type masonry products. This includes installation of grout, caulking, tuck pointing, sand blasting, mortar washing, and cleaning and welding of reinforcement steel related to masonry .
Solid brickwork is made of two or more wythes of bricks with the units running horizontally (called stretcher bricks) bound together with bricks running transverse to the wall (called “header” bricks). Each row of bricks is known as a course. The pattern of headers and stretchers employed gives rise to different ‘bonds’ such as the common bond (with every sixth course composed of headers), the English bond, and the Flemish bond (with alternating stretcher and header bricks present on every course). Bonds can differ in strength and in insulating ability. Vertically staggered bonds tend to be somewhat stronger and less prone to major cracking than a non-staggered bond.
