exterior wall movement

[steve mcgown]

Can anyone please give me an opinion on what causes an exterior (brick veneer) wall to show movement towards the top of wall (when pushed). Is it foundation issues? Brick tie failure? mortar joint failure? How would you report this?

Thanks in advanvce

Most brick veneer walls on residential structures are basically a free standing wall. If built with the typical 1-inch gap between the brick and the wall behind the center of a long wall at the top will be the easiest point to push. If the house has brick on all four sides the the closer you get to the end the less likely you will be able to push the wall because the side wall provides support. Brick ties are there to prevent the brick from pulling away from the wall, they provide little resistance against pushing.

The company I used to work for always speced these ties out (305 & 315).
They do 'help' prevent vertical movement.

after working with these ties, it's my opinion the corrugated ties are really worthless (just MY opinion).
