Hydraulic cement is the answer. Enjoy your dry floor.

Hi Carol. Remove it all. If you can't, hire out. You must get up all the flooring as moisture and mold may be lurking underneath. If the leaked hasn't been addressed, do that too. Only then consider re-sealing the floor. I suggest using an epoxy paint.
Mold is already there, you wrote. Get the water draining away from the house first. French drains, downspout extensions, 4% slope away from the house.
Mold is getting into your entire home via the HVAC system.
What about "Flex Seal"?

Get professional strength bleach at Home Depot or Lowes, mix with water as directed on bottle and wear rubber gloves to wash moldy areas first. Use fan for air circulation and if possible open windows to vent bleach fumes. Let dry completely.
