I have a 35 year old house with my shop in the basement

The outfit is LCR - liquid concrete repair.

I'm a basement shop guy too. Its a walk out so I can drag in all sorts
of projects. Got one huge crack that really leaks. i'll give this
stuff a try.

The process that seams to work best up here is one where they drill
into the crack at an angle, so the bore catches the crack about
mid-wall. They inject a resin - I think it is a poly-urethane - not
sure - and it fills the crack from the center out, both ways with an
expanding and somewhat flexible material that REALLY sticks to the
concrete.
