RE: Expansion Joint
We hardly ever use expansion joints in foundations or grade beams. The foundation itself does not need to be designed for expansion because the temperature is relatively constant since it is buried in soil. As for expansion of the superstructure, the resulting expansion forces are simply resisted by the foundation at the base of the column.
In your case, I am assuming you have a 6' or 8' high chain link fence. Any expansion of the fence mesh will simply cause it to buckle between the fence posts. No need for an expansion joint.
