GPR Underground Utility Locators

Pipes | Gas, Water, Sewer, & Power Lines | Wire & Cable Locators

GPR can detect traditionally non-locatable subsurface features including

  • Metallic & non-metallic pipes (PVC, Asbestos cement, Concrete storm and sewer systems)
  • Utilities with broken or damaged tracer wires
  • Underground storage tanks
  • Drainage tiles
  • Non-utility structures (Vaults, Foundation walls)

GPR complements traditional Electromagnetic (EM) Technology by:

  • Delineating utilities in close proximity
  • Providing reliable depth estimates
  • Allowing for data visualization to better map the subsurface
  • Reporting and archiving results for future reference
  • Integrating data with third-party software (eg. Google Earth)

Locate & Mark™ Utilities

Non-destructive & Non-invasive method to detect buried utilities.

Public utility systems and local governments require that the positions of underground systems are located and marked. This helps in planning projects, avoiding risks, damage prevention and hazards.

GPR data is saved and available for post-survey analysis and reporting, providing accurate records for future reference and comprehensive deliverable for your customers.

Locate & Mark™

Quickly & accurately locate buried pipes and mark their location on the ground in real-time while on-site

Traditionally “non-locatables” Utilities

GPR can locate both metallic and non-metallic pipes and cables. This provides a complete picture of the underground, and helps to ensure that nothing was missed using traditional locate methods.

Utilities close to each other

GPR can map all utilities in a single survey. With the availability of in-field interpretations and viewing options, the multiple utility lines can be mapped easily on-site.

Locate abandoned or untraceable utilities

GPR can locate abandoned and non-locatable utilities that may not be detected with traditional methods. In this example, the utility on the left could not be located using an EM pipe and cable locator. The GPR easily mapped the two utilities in the area, to ensure proper action could be taken prior to excavation.

Utility Locating with GPR? – Get the most out of your data!

GPR is now a complementary tool to EM when locating buried utilities. Unlike active EM methods where an individual utility is excited, GPR sees any buried feature that differs from its surroundings which can result in many targets being observed. This...

GPR for Flood Damage Assessment

In the spring of 2017, southern Quebec, Canada had unprecedented rainfalls and widespread flooding. Rivers in the Montreal area burst their banks and submerged communities. In one community, a local pedestrian pier was completely submerged under 3 feet of...
