Cables not buried under the surface

I am installing a new driveway, I am not a virgin media customer, but the cables are visible on my property,( barely buried under the turf )  and the junction box is on my outside wall .. my contractor has told me to contact you regarding this to get it rectified as he doesn’t want to damage any cables, when removing turf , there are flats above, which maybe where the cables are going, but the entrance to their property is at the rear.
