What caulk to use for basement floor/wall

We recently moved into a 42-year-old house with a full basement, concrete block walls on a poured slab. There is a gap, about 1/8" or less, between the wall and the slab. We had a general contractor out here doing some other stuff, and I asked him if I could caulk that crack to help keep out moisture. He said yeah, that might be a good idea, but I didn't think to ask what kind of caulk. Now I'm ready to do it, so... Is there some kind that would be better than "plain old" caulk?
thanks for any suggestions.

I believe you can get concrete crack caulking and filler. It's gray and very elastic. It fills in gaps too.

Read the label for instructions and uses, clean the gap as best as you can, then apply it with your caulking gun.

Yes, use the caulk made specifically for concrete crack filling. Vacuum out the crack well. caulk doesn't like to stick to dust too well.

If water is seeping from that joint, you have a problem that caulk isn't going to remedy.
