Larry,
   I hope this is not too late but most manufacturers specify a gravel 
drainage bed under the concrete.  The tubes drain into this UNDER the 
concrete.  If you have already sealed them up with 6 yards, then you are out 
of luck.  I hope you followed the manufacturers specs in rebar and placement 
of the base sections.
