For utility surveys, Venegroup Eng uses both Ground Penetrating Radar and Electromagnetic Induction (EMI) — two very complementary technologies. Venegroup Eng uses a mid-range frequency GPR system to scan for utilities; Venegroup Eng also uses an EMI-based SeekTech Ridgid Line locator. This equipment is the only line locator that uses omni-directional antennas, guidance arrows and an easy-to-read mapping display to lead you quickly and accurately to the target line, so you can have our scanning result in real time.

Utility-detection is a two-step process, employing both radio detection and GPR. Our goal is to identify the type and location of these utilities in order to prevent damage to them and the surrounding environment as well as protect your workers on the job site.
To provide the most comprehensive picture of existing sub-surface utilities on your job site, our ground-based services should be used in conjunction with your state’s one-call utility detection agency as well as any other utility data in your possession. GPRS is proud of our commitment to safety, and we encourage our clients to obtain as much information as possible about project areas in order to ensure a secure and responsible work environment.
In order to provide the most comprehensive utilities survey, GPRS employs electromagnetic induction technology in conjunction with ground penetrating radar on sites. We use hand-held electromagnetic induction equipment (RD-7000) consisting of a base unit and a wand to locate metallic pipes, live electrical currents, or signals from live communications wires. We may use electromagnetic induction, for example, to assist in areas where soils are not conducive to locating utilities using only GPR technology.

By law, you must locate utilities before beginning any sort of excavation project. Before doing any digging, everybody needs to call their respective 811 State One-Call. However, this free service only covers underground public utilities from the street to service meter and does not cover private utilities. For residential customers, private utilities may include gas lines for a heated pool, electric lines for a shed, garage, or barn, and certain sewers. For commercial customers, private utilities may include parking lot lighting, fire mains, and building-to-building utilities.
To guarantee location of private utilities, customers need to contact a private utility locating company such as Venegroup Eng. To provide the most comprehensive picture of existing sub-surface utilities on your job site, our ground-based utility detecting services should be used in conjunction with your state's one-call utility detection agency as well as any other utility data in your possession.
