I am having the foundation dug to put sealer on since basment is leaking. I noticed a crack about half-way up on two sides of wall that are leaking. Is this a problem? And when I go to fill this trench back, do I use clean stone or modifyed stone? I heard different things. Do I need to support the two walls when I back fill? I'm not looking for a free ride, but budget says I have to do this myself. Thanks.

Foundation:
1) FOUNDATION CRACKS:
Cracks need to be filled with epoxy fillers if possible. Otherwise treated with outside edpm membranes or foundation coatings.
2) STONE:
Backfilling requires at least 3-4 feet of clean stone installed over perforated drain tiles, with a filter fabric or polyethylene sheet between the trench wall and stone, and final soil placed over the stone with the filter fabric/poly between the stone and topfill.
3)WALLS:
Walls should be supported if and when backfilling under all conditions when possible.

Supported how? I have this dreaded feeling I will need to do this to my house after finding water in the basement where no pipe exist and no water on the walls, which leads me to believe it is coming up from under the slab, or the footing.
If I do it, I may be doing it in small sections at a time, and not a total perimeter excavation.
