I use a product called Water Plug. I got it at Lowes or a plumbing supply store. It is a powder and comes in a can and you add water and mix, then push tightly into the hole or crack. You have to work fast, since the stuff hardens in 15 minutes. If it is a big job, you should do it a little at a time to avoid it hardening before you are finished. It swells as it hardens to stop leaks.
If you dont have a problem with water coming in, then I would just use cement.

I would call a supply store and ask about what they have. RJ ----- Original Message ----- From: Lee A. Stone To: Blind Handyman Sent: Wednesday, December 16, 2009 11:23 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 -- Q: How many Californians does it take to screw in a lightbulb? A: Five. One to screw in the lightbulb and four to share the experience. (Actually, Californians don't screw in lightbulbs, they screw in hot tubs.) Q: How many Oregonians does it take to screw in a light bulb? A: Three. One to screw in the lightbulb and two to fend off all those Californians trying to share the experience. .
