mortarless brick paving over a base that con-
sists of compacted crushed stone, gravel, or
coarse sand (and hence flexible). Mortarless
brick system can be used over any base. By
contrast, rigid brick pavements consist of
mortared bricks over a concrete slab. The
slab should be sufficiently rigid to prevent
pavers and/or the mortar joints from crack-
ing. The semirigid base consists of asphalt
concrete (commonly referred to as asphalt).
Only mortarless brick paving is suitable over
this type base. A suspended diaphragm base
consists of structural roof or floor assem-
blies of concrete, steel, or wood. Suitability
of mortarless or mortared brick paving for
this type base depends on the stiffness of
the diaphragm. Details of various brick
pavement systems can be found in several

2.5.6 Thin Brick Veneer
Thin bricks, commonly referred to as “thin brick veneers” are thin fired clay units which
are used for interior and exterior wall coverings. They have become extremely popular
in commercial, residential, and do-it-yourself markets. Thin bricks are produced from
shale and/or clay, and kiln-fired. These units are produced to conform to ASTM C1088:
Thin Veneer Brick Units Made from Clay or Shale [2.18], and similar to facing brick
units [ASTM C216 (2.14)] except that they are approximately ⁄ 2 to 1 in. thick. ASTM

C1088 covers two grades for exposure conditions: Exterior and Interior, and three types
