Welcome

Subsurface utility locating services utilizing Ground Penetrating Radar (GPR) and Electromagnetic Detection (EM). Subsurface utility locating is highly important for soil boring, excavation, directional boring, As-Built confirmation, and retrofit design.  

Subsurface Utilities to Consider Prior To The Start of Your Project: Electrical, Gas, Communications, Sanitary Sewer, Storm Drains, Steam, Potable Water, Fire Services, and Irrigation

Ground Penetrating Radar (GPR) often referred to as Concrete Scanning or works by sending a pulse of energy into concrete and measuring the strength and time of the returning signal. The equipment will repeat this action multiple times as the unit is maneuvered across a surface and process the returning data points. This processed data will then appear on the operating system’s monitor and is interpreted by the GPR Operator.

Our GPR equipment does not cause any disruption to a site and whether you need us to search for an unmarked clandestine grave, or simply need to locate known graves at an older graveyard, Echo GPR Services can provide you or your organization with accurate and reliable results that do not disturb existing conditions.  

We can collect data using GPR to locate voids or sinkholes in fields, under asphalt/roads, beneath concrete slabs (interior and exterior). This type of detecting/locating can help indicate the presence and extent of any potential voids or sinkhole and guide future repairs.
