Integrated Applications

Seepage and Leakage Investigation

It helps operators and engineering teams prioritize where to inspect, validate, and implement remediation for water-related subsurface concerns.

Definition

What this method is

Seepage and leakage investigation uses resistivity-led and integrated methods to map possible water pathways that may affect structure performance.

It helps operators and engineering teams prioritize where to inspect, validate, and implement remediation for water-related subsurface concerns.

How It Works

From field measurement to interpreted model

  1. 1Known leakage history and structure context are reviewed to define target zones.
  2. 2Resistivity and supporting methods are deployed to map conductivity contrasts linked to possible seepage pathways.
  3. 3Outputs are interpreted with engineering and hydrologic context to guide follow-up validation and mitigation.

When to Use

Best-fit conditions for this method

  • Dams, embankments, ponds, and water-retaining structures with seepage concerns
  • Pre-remediation investigations where leakage pathways are uncertain
  • Monitoring-focused programs that need baseline pathway mapping

What It Can Help Identify

Subsurface features and signals

  • Possible seepage pathways
  • Zones of elevated water movement risk
  • Priority validation and remediation areas

Deliverables

What you receive

  • Seepage interpretation map
  • Risk-priority recommendations
  • Follow-up validation guidance

Typical Outputs

What the data looks like

  • Potential seepage pathway map
  • Anomaly profile sections
  • Mitigation support notes

Applications

Common applications in the Philippines

Dam and embankment seepage assessment

Canal, pond, and retention structure leakage screening

Infrastructure programs with persistent wet-ground anomalies

Method Limitations

What this method cannot do alone

  • Seepage interpretation is non-unique and must be correlated with engineering, hydrologic, and direct investigation data.
  • Seasonal moisture and operational conditions can influence measured response.

Geophysical results are interpreted models based on measured physical property contrasts. Results should be correlated with boreholes, test pits, drilling, geological mapping, laboratory data, or other direct investigation methods where required.
