Private utility locating identifies underground utility lines that may not be covered by public utility marking services. Our team uses advanced locating equipment to help identify utilities before excavation, construction, or other ground-disturbing work.
Utility locating is recommended before excavation, drilling, trenching, grading, or construction projects. Locating underground utilities in advance can help reduce the risk of utility damage, project delays, and costly repairs.
Ground Penetrating Radar (GPR) scanning uses radar technology to detect subsurface features and potential underground utilities. It can be useful for locating buried objects, voids, and other structures without extensive excavation.
Yes. Our concrete scanning services help identify embedded utilities, reinforcement, conduits, and other objects within concrete before cutting, drilling, or coring. This can help contractors work more safely and accurately.
