I've done that at K8CC.  The shack is approximately 12'x18' with four main 
operating tables.  At each corner of the room, I drilled completely through 
the concrete floor and installed an 8' guy rod.  Each grounds for each 
table go to the nearest ground rod.  This is for a 
multi-op/multi-transmitter setup, so the multiple grounds don't create 
ground loops.  When doing single-op with SO2R (you knew I'd get that in 
there somewhere :-)) all the gear in use is on one desk, working to a 
single ground.

I've never had water entry problems with these ground rods.  My property 
has good natural drainage.  Also, I stayed away from the weep drains.

One nice thing about operating from the basement is that I believe there 
are less problems from RF getting into the equipment.  I've never had RF in 
the stack on HF except once when I had a low 80M dipole over the house.  My 
nearest tower is 75' away, and I have no problem with computer noise either.
