Using a pressure washer is a good idea.
I obviously failed to mention that if I'm standing in the basement, the
space is overhead. Regular concrete will only drip out before it
sets...I think. Hydraulic cement hardens much faster, I believe.
And I think foam insulation is water resistant, not water proof. But I
may fill some of the void with it so the cement has something against it
in the back.
I had another idea. To systematically use water from the garden hose to
see exactly where the water is coming from.
