Ground Penetrating Radar (GPR) Services / Geophysical Surveying
Remote sensing, such as Ground Penetrating Radar (GPR), is used to locate and define the nature of buried objects without disturbing existing conditions. GPR is capable of detecting objects that range in size from wire mesh (millimeters), to geological features (hundreds of meters). The GPR instrument used by Impact Environmental is the GSSI SIR System-2®.
