Structural load-bearing tile is made from 4- to
12-inch thicknesses with various face dimensions. The
use of these tiles is restricted by building codes and
specifications, so consult the project specification.
Nonload-bearing partition walls from the 4- to
12-inch thicknesses are frequently made of structural
clay tile. These walls are easily built, light in weight,
and have good heat-and-sound insulating properties.
Figure 4-23 shows the use of structural clay tile as
a back unit for a brick wall.
Figure 4-24 shows the use of 8- by 5- by 12-inch
tile in wall construction. Exposure of the open end of
the tile can be avoided by the application of a thin tile,
called a SOAP, at the corner.
Stone masonry units consist of natural stone. In

natural state without any kind of shaping. In ASHLAR
masonry, the faces of stones that are to be placed in
surface positions are squared so that the surfaces of the
finished structure will be more or less continuous
plane surfaces. Both rubble and ashlar work may be
either RANDOM or COURSED.
Random rubble is the crudest of all types of
stonework. Little attention is paid to laying the stones
in courses, as shown in figure 4-25. Each layer must
contain bonding stones that extend through the wall,
as shown in figure 4-26. This produces a wall that is
well tied together. The bed joints should be horizontal
for stability, but the builds or head joints may run
in any direction.
Coursed rubble consists of roughly squared stones
assembled in such a manner as to produce
