I had two holes in the poured concrete floor of my cellar. I was planning to fill both holes. So far I have only filled one because I ran into a problem with the other one.

How I filled the first hole: I removed any crumbled edge pieces. I mixed the "rapid set mortar mix," using a liquid mixture that was half "concrete bonding adhesive" and half water. I removed the standing water from the hole. I painted pure "concrete bonding adhesive" to the edges of the concrete floor (which was surprisingly thin, by the way). I was supposed to let that dry before continuing, but I couldn't because of the generally damp conditions. I put the mixed mortar mix into the hole and pushed down on it with a piece of wood. I smoothed the surface with a rubber gloved hand.

The problem I encountered with the second one: water wells up (slowly) from below one edge of the concrete floor.

Question: how can I fill the hole, given the slow but constant influx of water?

Size of filled hole: approximately 5 inches in diameter.

Size of other hole: approximately 12 inches in diameter (slightly oblong shape).

Notes: The water trickles towards the sump pit where it gets pumped out with a sump pump. I am also working on figuring out how to eliminate the water entry in the first place, but in the meantime I would like to fill that remaining hole.
