Hello drier-than-me folks; First, I know this is a home theater forum and not a Bob-the-Builder forum, but this nasty leak is in my basement HT and it's going to halt my HT renos until I can control the water problem. Plus, you guys are smart and maybe you've dealt with this before. So, I had water come in through a crack in my wall. It's a poured cement wall, not a block wall. I am pretty sure, based on visual evidence where it's draining downward on the outside, and approximately where it's coming in on the inside. I have already framed/insulated/vapour-barriered and drywalled this wall, so I'm sort of stuck on the inside. I really want to avoid removing all of my work to date. Mildew could be a problem inside the wall. First, I have used Roxul insulation, which does not rot like the pink stuff, and second, I have thought about cutting a small hole in the wall and vapour barrier, and blowing warm air in from my vacuum cleaner to hopefully dry any remaining moisture between the wood studs and cement wall. Worth it? Next, I want to fix the crack. I plan to dig down to the footing on the outside of the foundation, in the spring, find the crack, drill and inject epoxy AND do the black goop and waterproof membrane. Double wammy. So here's what I need a bit of help on. Have any of you done outside patching of cracked concrete walls? Any further suggestions on how to do it properly? I'd like to avoid ever having this happen again and killing another basement carpet. Lastly, I'll be adding eves troughs which are absent now, re-grading the land around my house to slope away from the wall at all places, but my main question is just the how-to about fixing cracks from the outside. Also, would you be worried about mildew inside the basement wall that leaked? What lengths would you go to, to fix that problem? Thanks in advance for any help. Tom Kay, Ottawa.
