cocnrete basement crack leak

Okay, my 4 year old house has two small cracks in the foundation. They leak whenever it rains. Of course I am now ready to finish the basement and obviously don't want water coming in and ruining my walls and carpet.

I have done some research and it looks like I can buy hydraulic cement at Hime Depot. My buddy's house had a pro do that to their foundation crack some time ago. And it leaked after about a year.

What about this? It's a DIY concrete basement repair kit

Anyone know about this stuff?

Can I use it on my floor cracks, too? There isn't any water coming up right now, but I want to fix any cracks before I put carpet down and they get wet when it rains.

skootch,

Have you owned this house from when it was new? If so, I would call the builder. If he is a reputable builder, he will stand behind it and make sure it gets fixed the best way possible....If not;

The best patch jobs I have seen on foundation walls are with a fiberglass tape and a gray colored adhesive patch type substance. I'm not sure of the trade name for it but a call to a cement contractor that does a lot of basement wall jobs would know what it is.

The cracks are not as much of a problem as the moisture. The first thing you need to do is correct the source of the water. Make sure your gutters drain away from the foundation. Install pipes that take the downspout water a few feet away from the foundation. If that doesn't correct the situation, you will need to have french drains installed around the perimeter of your foundation - down at the footings, which drain away from the house. This is a big project, but if it is not done, no amount or method of patching cracks will last for long. If that is not an option, you will need to have french drains installed inside the perimeter of your foundation, under the basement floor, which drain to a sump with an electric sump pump. That way, when water enters the basement, it drains away through a gap between the wall and the floor, harmlessly under the floor without doing damage. However, you will still get a lot of humidity in the basement.

The suggestion about getting the builder to take remedial action is a good one. Try that first, but do your homework and make him do it right, not just a temporary fix.
