Electrical Resistivity Survey in progress

Professional Electrical Resistivity Survey Solutions

Electrical Resistivity Survey is a geophysical investigation method used to determine subsurface geological conditions by measuring the electrical resistivity of soil and rock layers. Vertical Electrical Sounding (VES) is carried out to determine the vertical variation of resistivity with depth, helping identify subsurface lithological succession, weathered zones, fractured formations, and groundwater-bearing aquifers.

Groundwater Exploration

Delineation of groundwater potential zones and aquifer characterization for sustainable groundwater development.

Subsurface Mapping

Identification of depth to bedrock, overburden thickness, and subsurface lithology mapping using resistivity analysis.

Borewell Site Selection

Selection of suitable sites for groundwater abstraction structures based on scientific geophysical data.

Non-Invasive Method

Non-destructive and cost-effective survey conducted using standard electrode configurations as per CGWB practices.
