Ground Penetrating Radar (GPR)

In brief, GPR is the application of electomagnetic pulses, transmitted into the ground which are then received by the inbuilt receiver, and are subsequently processed and interpreted by the Surveyor (see a typical GPR image on the right).

Within the utility location industry GPR is mainly used for the detection of non-metallic services, such as polyurethane pipes, fibre optical communications, PVC ducting etc. Also detectable by GPR are other sub-surface features, such as, underground tanks, voids, culverted watercourses, covered foundations and re-bar within concrete.
