EM and GPR locating in Middletown, Bear, Townsend, Odessa and Delaware City.
Trinity Subsurface locates private underground utilities for contractors, engineers and facility owners in Middletown, Bear, Townsend, Odessa, Delaware City and the rest of southern New Castle County, minutes from our Wilmington headquarters. Our technicians find the electric, water, gas, storm, sewer and communication lines that Miss Utility 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.
Delaware requires excavators to call Miss Utility of Delmarva (811) before digging, but utility owners mark only their own lines, usually up to the meter or property line. Southern New Castle County is one of Delaware's fastest-growing areas, with new subdivisions, schools, warehouses and commercial pads along Route 1 and Route 301. New private services tie into older rural lines that never made it onto a drawing: private water, sewer and electric, irrigation, site lighting and farm-era 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 (302) 407-3697 and the scheduling team will tell you what is possible.
