Hairline cracks in foundation leaks in heavy rain

Hello,

I have a few hairline cracks in my foundation that will leak when it rains heavy. Is there anything a DIYer can do to them to stop this?

Thanks,
Steve

The only proof positive way of eliminating water intrusion in a leaking foundation is to treat it from the outside. Yep, it means digging up around the foundation and applying adequate water proofing membrane and sealant, along with a good weep drain tile system where possible. DIY, not so friendly, but it depends on your expertise level and what type equipment you have in your shed.

Now, you can help alleviate it by ensuring your gutters are in top, clean shape and downspouts empty many feet from your foundation to a lower spot, and generally landscape the area so the natural fall of water is away from the house.

I should have mentioned that this leak is above grade and appears to be coming from a crack from the corner of a window. The crack is evident from the corner of the windows and extends downward.

I want to apply a vinyl concrete patch to the cracks from the outside, but was wondering if there is anything better.

Thanks.

Steve....a picture of that window from the outside would be real helpful.

I'm thinking maybe some kind of flashing could be added above the window .

Attached is a picture, one is from the inside of the house and it is hard to see the crack. The other is from the outside. You can see my attempt on the outside picture at a temporary patch that worked for awhile.

I think that this should be fixed from the outside. I am thinking of using vinyl concrete patch unless there is a better way.
