A few years ago I fixed my foundation leak by my septic pipe. The
ingress seal was tar and it was not laid on very well. I re-tarred and
used tar paper over it to protect it... seems to work.

I have had a leak in my machine wall now for a couple of years.
I ripped the wall down today because yesterday it was coming in hot and
heavy.

Well I found a nice large crack in the wall.. poured concrete from top
to bottom.

I'm thinking I have to dig out the foundation like I did for the septic
pipe.... I'm curious for a crack of that size what would you use to
patch it over?

Epoxy ladden sealer?
Quickcrete w/vinyl?
Something else?

I have to find what is causing the crack too.
Wonder if whomever put in the underground downspout went sideways
instead of away, and it's leaking.

Digging is the only way as far as a real fix goes. For repair, I would go
with a caulk like windshield caulk that will stay flexible. Any foundation
crack will open and close a considerable amount as the seasons change.
Also, put at least a 2 foot wide by 1 inch thick layer of fiberglass mat
board (unlined at least on the side against the repair) all the way down to
the footer drain pipe. This will keep water from lying directly against the
weak point which will help prevent pressure from building up and pressing
the water inward. There is actually a waterproofing system called tuff and
dri that works on a principle like that, and it is _guaranteed_ not to leak
for a really long time. I would never build a basement without it.

FILL the crack with a urethane product. The guys that do the "best
job" around here drill ito the crack at an angle from the inside and
pump the urethane product in under pressure - ir fills the crack from
the middle of the wall out, totally sealing the crack.
As for moving, if the crack moves a measurable amount with season
changes you've got more trouble than just a water leak!!!
