Locating Underground Utilities
Directional Boring Is Much Safer With Ground Penetrating Radar (GPR)
From Wikipedia: “Directional boring, commonly called horizontal directional drilling or HDD, is a steerable trenchless method of installing underground pipes, conduits and cables in a shallow arc along a prescribed bore path by using a surface-launched drilling rig, with minimal impact on the surrounding area.” http://en.wikipedia.org/wiki/Directional_boring
I work for a company(SIS GPR) in Birmingham, Alabama which identifies underground utilities and we’ve had a ton of jobs where clients call us to locate AFTER they bore into gas/water/power mains! The *main* reason these mistakes are made is because 8-1-1 rarely calibrates their equipment for depth. Directional boring purely relies on depth calculations when steering the bore path especially if they are heading in a perpendicular direction towards a specific utility. With Ground Penetrating Radar, SIS GPR is able to locate these specific utilities in real-time just like 8-1-1 however, unlike 8-1-1 we are REQUIRED to calibrate our equipment on site for each job to accurately identify depths of utilities. Remember, 8-1-1 only locates in the right-of-way while privately owned companies can locate almost anywhere.
