How can I fix a crack in my driveway without losing my electric fence wire?

It’s a bit tricky without seeing the crack, but if the wire was intentionally placed there, you won't want to close it off completely. If you can, consider rerouting the wire before you fill the crack. But if securing the wire is your top priority, try using something pliable, like small balls of clay to keep it in place without making it permanent. It really depends on how wide the crack is.

First, try cleaning the crack as best as you can using a hose or a pressure washer. Then, push the wire deep into the crack and grab a tube of concrete crack filler or sealer to apply with a caulking gun. This should do the trick!
