EM and GPR locating in Newark, Jersey City, Raritan, Branchburg and across North and Central New Jersey.
Trinity Subsurface locates private underground utilities for contractors, engineers and facility owners across North and Central New Jersey, from Newark, Jersey City and Elizabeth to Edison, New Brunswick and Somerset County's Raritan, Branchburg and Bridgewater. Our technicians find the electric, water, gas, storm, sewer and communication lines that New Jersey One Call does not mark, using electromagnetic (EM) equipment and ground penetrating radar (GPR), mark them in paint and flags, and deliver a field sketch within 24 hours.
New Jersey requires excavators to notify New Jersey One Call (811) before digging, but utility owners mark only their own facilities, usually up to the meter or property line. Port and rail property, older industrial land and dense urban blocks around Newark and Jersey City, and the pharmaceutical and corporate campuses of Somerset and Middlesex counties carry private lines beyond that point: process piping, fire services, site electric and abandoned utilities. They are private, and only a private locator will mark them.
Our team relies on a variety of technologies and methods to fully examine your site. We use electromagnetic scanning, ground penetrating radar and more to get the best info on subsurface utilities and underground infrastructure.
Our team offers multiple services to support your projects on top of utility locating and concrete scanning. Ask us about additional utility investigation services we can offer for further support beyond GPR locating and scanning.
We aim to provide ongoing support for your current and upcoming projects. Whether you're just starting design or running into unexpected utilities during construction, we'll investigate and assist with any step of your project.
No. Utility owners mark their own facilities, usually up to the meter or property line. Lines past that point belong to the property owner and need a private locator.
Most requests are on site within three business days, often sooner. Call (609) 795-8998 and the scheduling team will tell you what is possible.
