TA brick is a rectangular block of sandstone used as building material. These bricks are used for paving walls and hard surfaced floors. Thus the sandstone bricks are used for both walls and flooring. Though sandstone bricks are traditionally associated with the images of light browns and soft ochres which give a general impression of some cathedral or public building, they are also available in various other colors. Thus the walls made of sandstone bricks need not be painted instead the bricks of the appropriate color is chosen. The sandstone bricks are the best choice for paving walls since sandstone is quite hard, compact, fine, and possess good compressive strength and low absorption property. Combination of various colors is also used to impart an altogether a different look.
