Frostline offers a full range of utility locating services to conquer any type of project. With over 35 years combined experience, our personnel can be trusted to accurately locate and mark subsurface structures within your project area.

Ground Penetrating Radar (GPR)

GPR is a non-invasive, geopphysical method used to located non-metallic and metallic underground lines, structures and anomalies such as: Underground Storage Tanks (UST), Plastic Lines (water, sewer, gas), Septic Tanks, and Abandoned Facilities.

Concrete Scanning

This is a precise method of locating both metallic and non-metallic subsurface structures in concrete such as rebar, wiring, pipework, and structural reinforcement. 

Vacuum Excavation

This is a "soft dig" method used to uncover buried utilities in a safe and effective manner. Since it is the most precise locating method, the risk of damaging a utility during excavation activities is greatly decreased. By product produced from hydro excavation is disposed of in a manner that is compliant with all environmental regulations.

Sewer/Pipe Camera Inspection

Frostline’s camera inspection technology includes reel-mounted as well as robotic cameras, allowing us to locate and inspect any size underground conduit and/or pipe. The benefits of camera technology over traditional locating methods include: Video documentation, Integrity inspection, Identify the issue(s), Efficient (locates, inspects, and video logs simultaneously.

Utility Mapping

Physical field markings of utilities only last so long; mapping these utilities provides a living record of the subsurface features that were located. 

Damage Investigation

If a damage occurs, it is important to investigate and document the steps leading to the event. Frostline's personnel are trained to evaluate, document, and determine cause and extent of damaged utilities.


Private Utility Locating is essential to avoiding conflict with underground utilities and structures. The State One Call system only locates member-owned facilities up to the meter. Frostline uses various forms of locating technology to ensure project areas are safe for excavation activities.
