/diy/ - Do It Yourself

Need help with a small leak in my foundation.

House has a crawl space underneath it, but it's like a finished basement in that it has a poured concrete floor. At the very bottom of the foundation between two cinder blocks it looks like there's a small hole that's letting a tiny bit of water through when the ground is soaked.

It's the only place water is coming in and not much does. Can I use hydraulic cement to plug it?
