Advanced Technology Behind Every Locate
Util-Locate runs on advanced technology because guesswork doesn’t belong on a job site. Our utility locating service combines high-resolution ground penetrating radar systems, electromagnetic locators, robotic total stations, and survey-grade GPS to deliver subsurface utility investigation work that holds up under audit.
Field crews carry equipment that reads concrete down to the rebar layer, finds non-metallic pipes carrying natural gas, traces fiber optic cables across acres of campus, and pinpoints underground storage tanks buried decades ago. Output formats — PDF reports, AutoCAD DWG files, and Google Earth KML — give utility contractors and engineers immediate access to clean, professional documentation.
Real-time, on-site results let your crew make excavation decisions the same day, with no waiting for a vendor in another office to send drawings back.

Locating Underground Utilities in San Diego, California
San Diego County is one of the 58 counties that make up the state of California. The county was established in February of 1850, just a few months after California joined the union to become the 31st state. The county is roughly the size of Connecticut and is made up of 18 incorporated cities and towns and many more unincorporated communities. In 2011 the estimated population of San Diego County was 3,140,069, making it second only to Los Angeles County.
Much of this region's economic, social, and physical growth has been shaped by the unique and diverse geography. This area can boast of having miles of breathtaking coastline, lush, green valleys, lakes, and panoramic views of the deserts and mountains. The incredible geography, coupled with the mild climate, could be part of the reason that the population rose 10% between the years of 2000 and 2010. Population growth is a very big part of economic growth, and so it is welcomed by most. It can, however, present some major problems.
One of the problems with any sort of development is that you run the risk of hitting underground pipes or cables. A San Diego utility locating service can help avoid any dangerous or costly mistakes. If you are planning any type of development or excavation, whether it is commercial or residential, it is important to let one of the San Diego utility locators help you with the details. You can call the utility companies, but it may take days to get results, causing unwanted delays in your work.
There are many types of underground lines that you will need to be aware of before you begin, and a San Diego underground utility locating service can help you find their exact locations.
Cables/Wires: These types of cables are usually used to supply your house or business with services such as cable television and, in some areas, internet. While they may not present an immediate danger, you may be liable if you damage them.
Gas Pipes: Pipes are used to transport many utilities, such as your water and sewer, natural gas, or perhaps propane. Using a San Diego utility locating service can avoid the cost and mess of a broken sewer pipe or water main and the potentially dangerous situation of gas or propane leaks.
Power Line: Utility lines that run underground most often will be carrying electricity. Even if you know where the line comes into your building, there may be other lines that branch off to neighboring areas.
Util-Locate is a San Diego utility locating service that offers their services to contractors and commercial property owners. Don't risk injury or waste valuable time and money. Before you begin any type of excavation, call the experts and let them map your utility lines or pipes.
