Can someone told me what kind of masonary I should use for the outside of my foundation. And the inside foundation

Are you speaking of filling in cracks in your foundation?

If so, you can use "mortar" both inside and out.

PS. If they are significant, or include obvious bowing, you should have someone check it out to determine the cause. Any significant shifting of your foundation is caused by something that needs taken care of... not just a filling in of cracks.
