The concrete and brick conflict

This picture shows the cavity wall enclosing a multilevel parking lot. A brick veneer is tied to CMU walls.   The problem lies in the nature of these two materials.  New, dry brick irreversibly expands during the first year after production.  The opposite process takes place in the concrete that shrinks and creeps under dead load.

There are also some reversible thermal, moisture related and structural movements that create stresses and make this assembly restless. All those factors shall be taken under consideration and the brick shall be mechanically separated from concrete in such a way that the tightness and the structural connections are kept.

This photo shows a case where all those principles had been forgotten.

The concrete slab underside the slab touches the brick and will press down on the underlying brick courses causing vertical crack, additionally increased by the upward force of brick expansion.

Look at the photo below, what effort it took to shape this brick like that.  A mason wasted few bricks till finally achieved the result. Unfortunately, it would be better to have this joint below the slab edge left open.
