RE: Vertical joint in Matt (raft) foundation

I have become a big fan of StaForm.  It provides a good solution for the contractor, and as the structural engineer, I like it because it maintains a roughened surface.  It beats board forming and roughening the surface afterward.

What is there to consider when placing vertical cold joints in a Matt foundation?  I am placing the cold joint in between two columns, providing a continuous keyway and keeping the surface rough. 
 
 
 
Thanks in advance for any input,
