Hi everyone,

I'm not terribly concerned about my concrete having a hairline crack, it's unfortunate that the crack decided to go horizontal instead of vertical with the expansion joint, although there's nothing I can do about that. What I'm wondering is, is there a way to stop it from cracking further, and what type of product can I put in that crack to fill it in? Maybe a polyurethane sealant, using an injection needle, is what I was thinking. As always, any help is appreciated!
