Dam Seepage Investigations

CSR GeoSurveys Ltd. has extensive experience in utilizing geophysical methods to investigate, locate, and map anomalous seepage pathways in earthen structures, including dams, embankments, and tailings storage facilities. We specialize in using non-intrusive geophysical techniques, including electrical resistivity tomography (ERT), self-potential (SP), and electromagnetic (EM) conductivity, to identify seepage at an early stage, allowing for our clients to implement mitigation measures and prevent potential structural failures. 

The benefits of employing geophysical methods to investigate dam seepage include:

• Geophysical data can be collected over a large area, allowing for a more comprehensive dataset and therefore a greater understanding of seepage patterns.
• Geophysical methods do not require excavation or disturbance of the dam, allowing for operations to not be interrupted. 
• For large dams, where multiple measure points may be required, geophysical techniques are more cost-effective.
• Geophysical surveys can be completed proactively to limit remediation costs and environmental impacts.
