  • Ground Pentrating Radar (GPR)

    GPR works by sending a pulse of energy down into the subsurface and recording the strength and time required for a reflected signal to return. Reflections are produced when the energy pulse enters into materials with differing electrical conduction properties. GPR is very effective for locating USTs, utilities, piping, burials, foundations and ...
