As the Mid-Atlantic region’s leading provider of comprehensive subsurface investigations and utility locating services, Master Locators provides the first step to completing your project ahead of schedule and under budget. We partner with you to create smarter designs, more efficient builds, and safer excavations for all types and phases of engineering and construction projects.

We welcome the opportunity to show you how we add value to your client’s projects.


Ground Penetrating Radar

Ground penetrating radar, also called GPR, is capable of detecting most utilities underground, including concrete, fiberglass, transite, and plastic pipes that may not be detectable with conventional utility locating methods.


Hydro excavation is a new way to excavate. This technology allows us to safely dig or trench without damaging existing utility infrastructure. We can also perform “test holes” which expose underground utilities for precise quality level A utility information. Invert, size, material, and condition is among the data we collect when we expose an buried pipe, cable or conduit. Vacuum Excavation also works perfectly as a “pre-clearing” excavation tool for boring holes prior to bringing in the heavy equipment.

Private Utility Locating

Our work begins where the 811 locating system ends! Master Locators does not replace the 811 “Call Before You Dig” service. We supplement their work by continuing to locate buried utilities beyond the meter. If you are ever unsure of what you need for your projects, don’t hesitate to give us a call!

Video Pipe Inspections

With the use of our specialized video pipe cameras, we can inspect the interior of your pipes and conduits with a non-intrusive approach. We can determine condition, blockages, breaks, and missing laterals with the use of video.

Concrete Scanning

Our concrete scanning and imaging services can detect utilities in the concrete slab, floor, pad, or wall you need to cut or core. With state-of-the-art Ground Penetrating Radar (GPR) equipment, combined with electromagnetic locators, we can detect the location of rebar, conduit, post tension cables, slab thickness and more.

Leak Locating

Leaks can be safely and non-destructively detected with our comprehensive leak locating service. We can listen to the pipe for leaks using manual listening devices, digital correlators, or helium gas injection that can detect common water and forced air leaks. We can also safely expose the leak with vacuum excavation. We are emergency ready!

Utility Mapping & CAD Services

With the use of sophisticated GPS and survey equipment, we can build an existing conditions plan of the utilities on your property. We can build a new map from scratch, or add and update your existing CAD (.dwg) files

Cable Fault Locating

Finding a fault in a cable can be a daunting task. We have trained technicians ready to find that fault for you, with our fault locating equipment.
