Hairline crack in concrete walkway

I did see a similar question asked when I searched this forum. I am hoping to get a more complete answer to my question.

We have a concrete walkway. It's a low traffic area and the walkway is about 7 years old. It's in very good shape.

We did a bad thing and accidentally ran a heavy piece of equipment over the corner of the walk. We now have a diagonal 2 foot long, very fine, hairline crack in the concrete.

What are the steps to repairing this crack? I apologize but I'm good at screwing things up but not experienced in repairing concrete. Please take nothing for granted. :-)

A bit more information regarding the crack

Because it is such a fine crack, only just started and hasn't split, it is not possible to get even very fine sand into the crack.

I am not an expert in this field but most concrete repair products I have used require a certain amount of the surface to be grooved out (1/8 to 1/4") to give the repair product something to cling to. Watch tis post for the experts answers. Good luck.

majakdragon is right. A crack chaser is the proper tool. If its just a hairline i would just leave it alone. Most likely anything you do to try and "repair" ( and i use that work lightly) will just make things worse in the long run.

Good Luck
