Hydraulic cement.

Greetings All.
We just had a sustained rainfall and luckily had very little water come
into the basement. The only spot it leaked through is a below grade
concrete wall. I thought I heard of a product that expands as it cures in
concrete. Is Hydroplug or Hydroseal something that sounds to familiar? Or
any ideas to work from the inside? I realize that a proper fix is from the
outside, but this was such a tiny leak, it's not worth digging in the
neighbors yard..... TIA, Mark
