EM and GPR locating across Allentown, Bethlehem, Easton and the Lehigh Valley.
Trinity Subsurface's Allentown office serves Lehigh and Northampton counties, including Allentown, Bethlehem and Easton, and north to the I-80 corridor. We locate the private electric, water, gas, storm, sewer and communication lines that PA One Call does not mark, using electromagnetic (EM) equipment and ground penetrating radar (GPR). We mark them in paint and flags and deliver a field sketch within 24 hours.
Pennsylvania's One Call law requires anyone digging to notify PA One Call (811) at least three business days before excavation. But utility owners only mark their own lines, typically up to the meter or property line. On the Lehigh Valley's warehouse and distribution sites, college campuses and older industrial properties, the lines past that point are often undocumented: site lighting, private water and fire services, storm laterals, and feeds between buildings. They're private, so 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.
