Comprehensive Locating Services
If you need to know where the private utilities are on your property or project site, ProMark is here to get the job done. We work with engineers, construction managers, contractors, homeowners and anyone else who needs subsurface utility location services. With an experienced team using up-to-date technology, we’ll get you the information you need.Schedule Work
Ground Penetrating Radar
Ground Penetrating Radar (GPR) uses radio waves to image the subsurface. It’s a non-invasive method of utility locating, so there is no digging required to determine where utilities are located below ground. You’ll quickly have information about subsurface utilities without causing disruption to your landscaping or structures on the property.
GPR is effective at locating metal pipes, conduits and other metal constructions underground.
Plastic, concrete, clay pipes, geologic features
Electromagnetic locating is a non-invasive method that utilizes transmitters and receivers to determine which utilities are located underground, as well as their location and the depth at which they are underneath our feet. This method can be done directly or passively, depending on the type of utility and the accessibility to attributes such as valves and conduits.
Linear Metallic Utilities
Pipes, conduits and other metallic utilities can be identified and mapped with electromagnetic locating.
Vacuum excavation safely clears the underground area around utilities. The method uses air to break up and suction dirt and debris out of the ground. Exposing the area around the buried utility can help get more precise results in situations where many utilities are crowded together. It also allows the condition of the utility to be assessed.
Metal pipes, conduits and other metal constructions underground can be located and assessed with vacuum excavation.
Water pipes, non-metallic gas lines, clay pipes and other non-metal utilities can be located and assessed with vacuum excavation.
Concrete scanning allows utilities to be detected in concrete structures without damaging those structures. This method can be used on columns, walls, or floors made of concrete to identify the location of structures underneath or within the concrete. With concrete scanning, metallic and non-metallic utilities can be located, as can rebar/PT cables.
Metallic & Non-Metallic Utilities
Metal pipes, conduits and other metal constructions can be located with concrete scanning.
Rebar and cables that are used to reinforce concrete can be located with concrete scanning.
The sonde locating method is used for non-metal pipes and ducts. This method uses a transmitter that is guided through a non-metal pipe by a flexible rod. As it moves through the pipe, the transmitter sends a signal that allows the location and size of the pipe to be mapped.
Water pipes, sewer pipes and other non-metal pipes can be found using sonde locating.
When you’re launching a building or excavation project, you need to know where the utilities are in the area. Our skilled team and up-to-date equipment will make sure you have the best information possible before you begin the work.
Bore Hole Mitigation
Our professional team can use their expertise to help you identify and mitigate the risks associated with bore hole drilling. If you’re a property owner or a company that does bore hole drilling, we can work with you to get the job done safely.
We frequently use our expertise to identify cables, rebar and other structures within concrete walls, floors and ceilings. Our equipment allows us to do so without disturbing the concrete.
Subsurface Utility Mapping
Using a combination of research and technological identification methods, our team provides clients with a map of underground utilities. Mapping subsurface utilities accurately is crucial for the safe, successful execution of many types of projects.
Locating underground Storage Tanks (UST) is a common need for property owners, contractors and others. USTs are frequently located using Ground Penetrating Radar, a technique our team is skilled in.
In addition to physically marking the area around utilities, we can provide a written report that delves into what we discovered and offers our analysis of the data gathered.
