Hi Lee,
The correct way to fill cracked concrete walls is to clean out the crack with a
chisel and mallet, with an undercut so the bottom of the crack is wider then
brush and wash it out thoroughly. They recommend using hydraulic concrete which
expands as it cures. You force it into the crack and trowel it flush. Because
of the wedge shape the expanding concrete doesn't just pop out.
Hope this is helpful.

Subject: [BlindHandyMan] reparing a solid concrete wall
I have a few new cracks in the wall a couple of them are verticl and
run from the top of the wall down to the floor. this solid concrete wall
. only goes to ground level andthen there is three layers of cinder
block. . the worst problem is a maybe 6 foot long new crack that has
opened up which is horizontal . that crack is wide and deep a few feet
it is as much as 5 inches deep and open almost 3 inches . so here is my
plan and tell me what you think. the deepest part of that crack I was
thinking of spraying in foam insulation . to do two things. to help fill
the gap but maybe also to give the new concrete something to bind to
if that makes sense. I know the deep crack or ther others must be damp
first so the old concretedoes not suck out the water / moisture from
what we put in. this all should make a good winter project as there is
some heat in the basement. . I could let it all go but then like a
neighbor get charged some $20,000 to replace the wall. Lee

lightbulbs, they screw in hot tubs.)
