Sealing Block founation

I have a cement block foundation exterior that I think I need to seal. In one corner, the mortor joints have shown some signs of small cracks. I figured I should seal, but don't know what with. I remember on time years ago on another house using a concrete type mix with fiber of some kind, but can't find this any more.

Any suggestions
Thanks

Check on " Applied Technologies "
Look for Hydro Stop.
Also check on the Water Proofing for interior walls and slabs.

Also look up XYPEX they have a brush on coating that works very well.

Try THOROSEAL from BASF, a cement sealant, which is applied on with a brush. It will bring you the results you are looking for.
