Ground penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. This non-destructive method uses electromagnetic radiation waves and detects the reflected signals from subsurface structures. GPR is limited on depth, depending on antenna frequency and electrical conductivity of the ground. For example, in clay, the conductivity is high, dissipating the waves and making it hard to penetrate decreasing depth. Dry or sandy soils are ideal for wave penetration. The GPR device is a necessary tool in The Underground Detective equipment arsenal, used in locating and searching for both metallic and non-metallic pipes, tanks, trenches, and voids in the soil. GPR is used on the majority of our jobs to ensure the utility knowledge as well as safety.Contact us to find out more information regarding how GPR could be utilized on your job site!
