Since there's lot of expertise in cement here on the forum, I thought I'd post this question about a repair I just found out that needs to be made.
My cement balcony floor has a crack near the edge / outside the railing. This floor is poured cement, over cinder block. I'm the second owner of the house. The floor must have been poured in 2007.
What is the best substance to use to fill the crack? I'm assuming that caulk won't do anything to structurally stabilize it.
Here's a couple of pictures of the crack. For reference, the paver driveway is 18 feet below the concrete floor, though it looks attached at first glance.
