Reparing foundation cracks

I am afraid that somebody may think that my original post is an ad or spam. It is not. I have a crack or two in my foundation through which water leaks when it rains hard.

Instead of digging outside and applying sealer, sealing the cracks from the inside may be an neat idea provided that it works.

Is it too good to be true?

Your input will be appreciated.

Our concrete company uses a product called Sika Flex. It can be bought at Home Depot, etc. We use this for cracks less than 1/8" wide. For wider cracks we chip out the crack to make it wider, fill the bottom with Sika Flex then use Rapid Set to patch over the top.

Thank you for your input.

So sealing the cracks from the inside can work, can't it?
