We have mentioned about some methods of constructing walls for buildings. All walls are мейд of different materials. For example, walls are made of brick1. The brick walls are laid up with a space between separate vertical parallel walls and connected with occasional cross bricks or metal ties. This method provides cavity walls.

In areas of possible earthquake damage2 the cavity in brick work and the open cells in concrete units is reinforced with standard reinforcing rods and fully grouted with a soupy mixture of concrete. Normal spacing for vertical reinforcement3 is 4 at 24" with 4 at 48" horizontal fully, encased in grout up to 10" high. Reinforcement requirements should be shown on the drawings for other situations.

But it is a special part of building called masonry. Masonry is installed with cement mortar at bed and end joints, usually 3/8" or 1/2" thick. The masonry includes a stone or brick work and concrete units. The concrete units are laid in a similar manner, but obviously there is no open space between inner and outer shells. Each unit has an open core. The concrete units are used primarily as foundation, exterior or fire-separation walls. The brick and concrete units are manufactured in standard sizes. Though a stone may be any size, thickness4, quality or color.
