I'm trying to understand exactly what you mean by mud jacking?
regardless, you're going to have to divert the water away from the house, by regrading or something. I don't think, you can stop it from inside? it must be stopped from outside!
epoxy injections at the crack will only force the water to find another escape in a different spot.
you might be able to cut a hole in floor where water is coming in, if is only a small amount? and install a submersible pump. running water outside, maybe 30-40 feet into a hole of stone with good drainage. that's what I had to do in my finished basement. the hole can be the size of a 5 gallon bucket, the pump needs to have an auto turn on/off with continuous power supply, with the power to pump out faster than coming in.
also leave an access panel into pump in case needed to replace? this can all be done for a couple hundred dollars.
as always, just my thoughts.
