    Role of GPR in Buried Utility Damage Prevention

    Modern society's critical dependence on the uninterrupted availability of telecommunications, power distribution, water/sewer networks and transportation systems has made damage prevention a greater priority.  Greater awareness of the costs of repair, service disruption liabilities, not to mention compensations for injury or death, have created a strong demand for more effective methods of detecting buried infrastructure.

    GPR for Buried Utilities

    Why Use GPR for Utility Locating?
    The tools and methods of locating buried utilities are quite diverse. The most common approach is energizing metal pipes and cables with electric currents and using a magnetic filed sensor to detect the current. Provided that the target can be exposed for connection or current can be induced, sufficient current flows on the target and the detector is sufficiently sensitive to detect the magnetic field created by the current, then this technique works well and is very cost effective.

    When access is difficult, electrical current does not flow (i.e. non-metallic utilities or broken connection), external noise makes detection impossible, GPR provides an alternative. GPR provides its own source of energy, detects both metallic and non-metallic objects, as well as detects disturbed soil and other buried structures.

    The Centre for Advancement of Trenchless Technologies (CATT) was established in 1994 to help municipalities address their buried infrastructure challenges with specific reference to trenchless technologies.


    Through shared responsibility among all stakeholders, the Common Ground Alliance (CGA) works to reduce damages to the underground infrastructure - ensuring public safety, environmental protection, and the integrity of services by promoting effective damage prevention practices.


    NULCA stands for the National Utility Locating Contractors Association. NULCA's formation represents a concerted effort by leading companies in the field to establish the highest standards to guide the industry's growth in both size and importance.


    The Ontario Regional Common Ground Alliance (ORCGA) is a non-profit organization dedicated to shared responsibility in damage prevention and in the promotion of damage prevention best practices.
