Have i been lucky (KNOCK ON WOOD) that i havent hit any lines or utilities. while boring under, roads, drives, sidewalks. To me this is the worst kind of break. I always call ULOCO. are here theyre called http://www.ncocc.org One close call a long while back, i was JETTING (back in the day lol) under a 8' wide side walk, i hit something near the end of the bore so i started hand digging the other side to finish and it was the main electric to the house!!! not even 8" under the grade. I remember hearing recently some cable co. bored though a 24" water main while boring under a roadway here in wilson. Although they were using a vermeer navigator pull fiber.
