Nick: If they're more than 1/4" wide, there are many, and/or they're very long, get a basement pro's consult first.
Otherwise, use hydraulic cement. Technically, they need to be fixed from the outside, which an be a costly horror of digging up the yard around your house.
Mine, of course, are directly under the deck. It would have to get ripped out to reach those areas.

When patches are done, use UGL brand waterlock prime. No other brand actually works.
