Resistivity Survey

Electrical resistivity tomography for subsurface mapping

Service Overview

Resistivity surveys use electrical current to map subsurface conditions based on variation in electrical properties of soil and rock layers. This non-invasive method guides drilling locations, assesses groundwater potential, and evaluates quarry and excavation viability.

When to Use Resistivity Surveys

• Groundwater assessment and borehole location
• Quarry and excavation site evaluation
• Contaminated site investigation
• Mineral exploration reconnaissance
• Subsurface water interface identification
• Soil layer differentiation

What's Included

• 2D electrical resistivity tomography (ERT) surveys
• Multi-electrode data acquisition
• Inversion processing and interpretation
• Resistivity model generation
• Geological correlation and analysis
• Borehole location recommendations
• Interpretation report with findings

Advantages of Resistivity Surveys

• Non-invasive: No drilling required
• Water Detection: Effective for groundwater mapping
• Cost-effective: Reduces drilling requirements
• High Resolution: Detailed subsurface images
• Large Coverage: Surveys wide areas quickly

Typical Deliverables

• 2D resistivity cross-sections
• 3D resistivity models (where applicable)
• Interpreted subsurface geology
• Groundwater level estimates
• Rock/soil contact identification
• Quarry viability assessment
• Interpretation report with recommendations
