I watched my well guy make a similar connection as to what you are describing. He installed a rubber coupling and then completely wrapped the joint/coupling in hydraulic cement, running the cement up the pipe a couple of inches on each side of the coupling. Looked like a cement coupling covering the rubber coupling. He let the cement setup and then wrapped the whole joint with water barrier tape.

Not sure what the hydraulic cement brought to the party but that is the way he did it.
