Insufficient Brick Anchoring
Anchored Brick Veneer Defect Results in Walls Cracking
Fiebig Architecture was hired to determine the cause of widespread brick cracking for a commercial building suffering from widespread brick veneer cracking.
Expert Opinion
The building code requires the anchors that hold the brick veneer to the wall structure to embed a minimum of 1 1/2 inches into the brick veneer. Upon removing several bricks to review the brick anchoring system, it became apparent that, due to an excessively wide cavity between the brick and the structural wall, the anchors were unable to embed the required depth into the veneer. This resulted in the brick veneer being unable to transfer loads through the brick anchoring into the structural wall behind it, which resulted in the cracking of the veneer.
