I am working on installing my P&M BL 28-40. We live in an old farmhouse built in 1780. It has the old stone foundation with a cement block wall built inside of it. I had a 9" hole bored through the wall ( it was almost 3' thick) that I plan on running the my logstar owb. pipe, 3 - 1" well pipes, 2 - 1" pvc. electrical conduits, and 1 - 1 1/2" pvc electrical conduit. The way my house is situated I only have access to one small area on the north side to run all my mechanicals into the basement. What would be the best way to attempt to seal this mass of pipes?
I had to make the hole 42" below grade to ensure that the water lines don't freeze. Any suggestions would be greatly appreciated.

Stiff mortar mix one bag at a time.  Let it set for a while and then then shape by hand.  I'm a concrete guy and have done quite a few of them.  Take your time it may take several days

I used hydraulic cement on mine and my brother-in-laws no leaks so far it's been 3 years

I'd slip the smallest PVC pipe over everything that has to come in, then use hydraulic cement to sea the pipe to the wall, fill the rest with spray foam fro the can then smear a thick layer of clear silicone on the outside to seal the foam. With the PVC outer pipe you can change something out in the future without messing with the cement.

I am a chemist so I say the heck with concrete/cement for this application. 

The best way?  I suggest you use Devcon Floor Repair instead.

Why an epoxy-based product for the repair?  Non-porous compound and has extremely low shrinkage and a great temperature resistance.  No cement or concrete product even comes close.
