Minimum size for brick ledge

How much of a standard brick can overhang the brick ledge? Or in
other words, how much of the brick needs to be supported by the
ledge. Originally I was going to use cultured stone so I only have
a 2 1/2" ledge in the concrete but have since decided to go with
brick. My mason wants to use 2 X 4 pressure treated nailed to the
concrete while he is laying the brick but when it's all tied to the building
he says the 2" on the ledge will be sufficient. Should I be concerned?

Thank you ,

Don't know where you are located, but if you're in an area of frost and this ledge is not below frost line, I would be very concerned about frost getting under the brick and pushing.

I think I would get someone other than a brick mason (such as a structural engineer ) to tell you if the brick can overhang that much. That engineer will probably want to know how high the brick is also.

Yes sir I would be very concerned at this method. Many things here are just wrong. 2" is just not enough to bare the weight of the wall. Wall ties are not really going to do much if anything if the wall starts to settle. They are designed for lateral movement, Keeps the wall from moving in or out.

I agree with the previous post have a engineer look at this one.
