Usually, bulges occur at shelve angles or relief angles.
Bulges in masonry veneer can be caused by:
- lack of adequate fastening
- undersize anchor bolts
- improper installation
- an undersize shelf angle
Cracks in masonry veneer can be caused by:
- improper jointing details
- poor quality or high absorption brick
- poor mortar
- differential wall movement
- base structure shrinkage
- excessive building drift
- inadequate ties, no ties, rusting
A licensed engineer must evaluate the conditions and determine appropriate remedial action.
An anchor system will not repair bulging or cracked masonry veneer. It may be necessary to remove a portion of the wall. However, the undisturbed masonry should be re-anchored to avoid more shifting of the wall during reconstruction, or to re-anchor a veneer that has shifted beyond its plastic limits.
