3M Scotchrap is what I have used in similar situations.  I have a cut sheet
for it if anyone is interested.  Let me know and I will email it out to you.
As far as drainage, Eric already mentioned it, a big ugly pit.

Subject: Re: Underground Dry Pipe

If I recall, on one project with a sidewalk siamese where we couldn't 
use regular DI for the underground portion, we used schedule 40 
galvanized with some kind of wrap and primer over. This might work in 
this situation. The drainage is still a problem.
