Geophysical Surveys (ERT, SRT & Electrical Resistivity Survey)

Geophysical Surveys

Geophysical methods are non-invasive techniques used to study subsurface characteristics for groundwater, mining, construction, and environmental investigations.

Electrical Resistivity Tomography (ERT)

2D/3D imaging of subsurface resistivity to delineate aquifers, fractures, weathered zones, cavities, and contamination plumes. Multi-electrode layouts for rapid coverage and higher resolution along alignments and site blocks.

Seismic Refraction Tomography (SRT)

Determines near-surface P-wave velocity structure to map bedrock depth, rippability, and thickness of weathered/overburden layers. Ideal for highways, bridges, industrial sites, and tunnel portals/alignments.

Electrical Resistivity Survey (VES/Profiling)

1D/2D resistivity sounding and profiling using Schlumberger/Wenner arrays for quick, cost-effective groundwater and lithology assessment.
