Cavanaugh offers Ground Penetrating Radar (GPR) underground location services. This non-destructive method of locating underground objects acts similar to a sonar. The specialized process can be used to find non-traceable structures like PVC pipe. It can be augmented with GPS Surveying to provide an accurate representation of a utility system.

Additionally, Cavanaugh utilizes Metrotech 810 line location equipment for traceable utilities such as water, gas and telephone lines. The services can be used for design locates that the North Carolina One Call Service does not provide.
