Tricky Water/Sealant Problem

Howdy,
I'll try to explain this clearly.
I have a stone retaining wall 5 feet from the back of my house. The wall and the foundation are built directly on the slate bedrock. There was a concrete "gutter" poured over the bedrock, in between the house and the wall. Ground seepage had been running along the bedrock, under the wall, under the "gutter," and under the foundation, into the crawlspace.
I have recently cut a trench through the "gutter," down to the rock, patched the gaps on the downhill side, between the old crete and the rock. So now, ground water flows downhill along the berock, goes under the retaining wall, into the new trench, and is diverted to a drainage pipe.
My question is: What is the best material to seal the seam between the new patch concrete and the slate bedrock?
Here's a pic to clarify:

You can buy an elastomeric sealant that comes in a caulking tube. This is available from most hardware stores. It is for filling cracks and seams in concrete. It will adhere to the two and is flexible enough to survive differentials in movement.

Hope this helps.
