Ground Penetration Radar
Ground Penetration Radar (GPR) utilizes pulsed high frequency radio waves to probe the subsurface without disturbing the ground. The GPR data are collected continuously as the instrument is towed over the ground surface and provides a real-time graphic image of the subsurface.
Seismic & Resistivity Survey
Seismic and Resistivity surveys are useful non-invasive, non-destructive tools that can investigate geological structure and rock properties. Seismic methods can rapidly characterize a site and determine elastic properties of soil and rock for geotechnical purposes, or estimate material density of the soil layers.
Electrical properties are among the most useful geophysical parameters in characterizing Earth materials. Variations in electrical resistivity typically correlate with variations in lithology, water saturation, fluid conductivity, porosity and permeability.
