I had a great experience with Apex Locating Services. Through 811 Dig, I had been unable after 2 visits by their contractor and one from the energy company to get a reliable location on the gas line to my home. Possibly the signal wire with the gas line was damaged during a septic repair. With the ground penetrating radar equipment that Apex uses, it was possible for them to give me a confident and reliable location for the utilities. I was finally able to move forward with my excavation projects thanks to their help!
