When the outfit (and that's putting it mildly) who installed my new driveway (over the binder) in my brand new home came, I gave them a length of Schedule 40 pipe to install as a conduit under the driveway in case I needed to electrify the outer yard beyond at a later date. I wasn't paying attention, and they put the pipe LEVEL with the driveway instead of 18" down, per code! I made them come back and sink the pipe to 18". They tried to patch where they made the cut, but now the crack is getting wider and wider. Is there a new fix for deep driveway cracks, like a laser or infrared something or other?
