I'm not sure it's the same product and it did work after they did the whole front of ther house, re and re all the drywall. Both floors of a double basement. (Mountain side house)

God sounds like a disaster.

Looking at the crack it is so small, where the water comes in, I'm not sure I could even force the epoxy in uniformly enough to get the job done. For the inside may just go over the crack and out a few inches on each side with foundation sealer.

Now I know why people prefer condos or rent.

Up until a few years ago I have always believed owning would be a winner over time and if the price is right today I still beleive.
Buying a condo isn't cheaper maintenance, it's just spread out over more people, like insurance. Which works fine until you get something like what happened up here when the prices were dropping a bunch of buildings also had leaks and some cost in the millions to fix. http://blogs.vancouversun.com/2009/05/04/leaky-condo-crisis-far-from-over/

The system I was talking about allowed for the epoxy to be deeply embedded into the crack as it installs ports along the crack and then seals up the crack at the surface before forcing the epoxy into the crack. If you just take a gun and squirt into a crack it takes the path of least resistance and will go in a little and then come back out around where you are putting it in. These ports are about 12 inches apart and the epoxy has no place to go except deep in the crack until it comes out the port above. I gather the spacing is important based on how thick the wall is etc. once it comes out the port above you then move up to that port and work your way up. It wouldn’t work on a block wall as you would have to fill the cores. I don’t know if this is the system Neil had experience with or not. And I have never tried it as I mentioned, but it did look like it could work.

It’s the hydrostatic pressure on the outside of the wall is the problem and water is heavy and if you have a high water table it’s going to be pretty hard to stop that pressure. If the crack was caused by settling and the water coming in isn’t under pressure it’s more of a weeping because there is an opening letting it freely come in. I would say something like that IMO would be a candidate for the epoxy fix.

I think there are youtube vids of this method on line.

much of our work is condo servicing so we do this often using hydrophyllic/hydrophobic polyurethanes,,, for a diy'er, i'd recommend emecole [ NO $ interest ] they have a diy kit that'll include bang ports & material,,, you need to 'butter' & flush out the crk w/water 1st,,, drill your portholes so they intersect the crk about 1/2 thru the bsmt wall, then start injecting from the btm up

works well on either gravity OR hydrostatic however, depending on the head of water, it will find another way to seek its own level
