At the grade line the face brick is started, sometimes with a rowlock course or a soldier course, set either flush with the outer surface of the foundation wall or, as usual, slightly projected, in which case it is known as the water table. On the other hand, the entire base or lower portion of the building from the grade to the first floor sometimes extends as a water table beyond the wall above. [Figs. 2-7] show various ways of treating this portion of the wall which add to the interest of the brickwork.
The method of laying the face brick is substantially the same as that for the foundation wall except that much greater care must be taken with the bond and mortar joints on the surface of the wall. A description of various bonds and patterns will be found on [pages 33-35].
Building
The method of bonding the face brick to the common brick backing follows the usual method Bonding means of headers every five or six courses, the headers in other than Common Bond, not used for bond, being cut in half. In the widely used Stretcher Bond where no headers occur except at corners, three methods of bonding may be employed. First, but only in case of walls 12 inches or more thick, the back corners of the face brick may be clipped so that the backing brick fit diagonally into the notches thus provided ([Fig. 8]). This sort of concealed bond is weak and should be avoided.
