You try to avoid geometry sharing a common vertex where collision could 
occur.
You can add a small offset

Ex  (ascii art !!!)

This can give you problem
  ______________
  |
  |  Geom1
  |_____________
  ______________
  | Geom2
  |_____________


Instead you can add a small offset

  ______________
  |
  |  Geom1
  |_____________
    ______________
    | Geom2
    |_____________
  |-|
   ^-- Offset
