The HGI trusted Methods
HGI has over 20 years of experience using seismic survey methods, such as seismic refraction, reflection, and MASW, to investigate geological, geotechnical, and hydrogeological projects.
Electromagnetic survey methods enable the measurement of electric or magnetic field components induced in the subsurface and are sensitive to variations in subsurface electrical properties.
Induced polarization (IP) is a versatile technique that quantifies the charge storage capacity of earth materials, with applications in hydrogeophysics and biogeophysics.
Magnetotellurics (MT) is a geophysical method that measures natural electric and magnetic field variations to determine subsurface electrical properties, with applications in natural resource exploration.
