You choose the epoxy carefully.  Epoxies in general are highly susceptible to creep, but some outfits 
(Master Builders is one that comes to mind) have special epoxies with a lower susceptibility than others.  
They, and I'm sure others, make epoxies for just such an application.  The tough part, once you have the 
right material, is to make sure it's installed properly.
