Fixing foundation cracks
I’m starting work on repointing my block foundation cracks. I have a few questions. I’m using a grinder with a concrete blade to clean up the joints. Do I need to remove all the mortar in the joint or just the loose motor? Before I refill the cracks can I add backer rod or just fill it in with mortar? What’s the best mortar to use? Any tips you have would be appreciated. Thanks

So be informed that when your working with block, your only dealing with the inner joint, there is still more to the outside that you can not reach.
If it's leaking you need to attack from the outside, internal repairs are not going to eliminate the issue!

That is a start, block and mortar are not good water proof, it typ takes an exterior membrane to redirect water to drain field!
