I need help determining what is the proper approach to sealing an incoming water line main through a concrete block wall.

The main water line is coming in about 2 feet below ground level. The space between the PVC pipe conduit and the water line leaked water during a heavy storm last night.

My initial thought is to pump silicone sealant into the void space. Any advice?

(Update: I went with a combination of silicon sealant within the void of the PVC pipe, then Flex Tape around the exterior opening.)
