Great Lakes GPR is honored to have been a part of the construction process by conducting a Utility Location Survey at the Detroit Water Treatment Plant.  Great Lakes GPR was contacted to conduct a Utility Location Survey for the purposes of; locating utilities and any subsurface features. As a result of using the application of Ground Penetrating Radar (GPR), Great Lakes GPR was able to detect the existence of subsurface utilities prior to the excavation of two areas designated for new construction at the Detroit Water Treatment Plant.

Ground penetrating radar (GPR) offers the means to detect embedded or hidden objects within the near subsurface. This non-invasive method uses electromagnetic energy to detect reflected signals from subsurface structures. GPR can be used in a variety of media including concrete, brick, asphalt, and soil. GPR can detect objects, changes in material, as well as voids and fractures.

Applications of Ground Penetrating Radar (GPR)

• Utility location
• Conduit location 
• Slab thickness 
• Underground storage tank location 
• Drum location 
• Duct bank location 
• Septic system location 
• Structural boundary surveys 
• Soil interface survey 
• Detection of bridge deterioration 
• Site assessment for Phase II investigation 
• Water table mapping 
• Shallow bathymetry investigation 
• Engineering site investigations 
• Hydrogeological investigations 
• Detection of sub-surface cavities 
• Location and orientation of buried metallic objects 
• Archaeogeophysical investigations 
• Forensic investigations
