			if  caulking is not  designed to be  exposed  in a  wide strip ......say , wider than  an inch ,  
then  why not  use  something  that is  designed  to be in full  sun ,
such as ,
the  white  'flat  roof' roofing   goop .  
the trouble   with a  wedge  shaped  concrete  strip , is , it's   brittle  and   won't adhere  to the  existing  concrete  slab ,  and  the  narrow  edge  will  crack off if anyone steps  on it  after  a  few  weeks.
i've been  trying  to  formulate a  fix  for  those  doors  for  years .   one guy  suggested,    make a 1 inch deep   saw  cut about  8  inches away  from the  door ,   then  use  aluminum flashing  ,  put  caulk  in the  sawcut ,  push the  flashing  edge in , then  bend it  up to the  door,  creating the  wedge  shape.
how to  attach to the  door?   not  sure.  this  is  what  stopped  me ,  we'd  need  a  waterproof and  12 foot  long  seal  between the  door and the  metal  strip.
i think a  slot  drain  would be  best.
