Drilling Services
Drilling services: provide controlled subsurface access for environmental,
geotechnical, and civil/industrial projects. They include geophysical surveys (GPR) to identify buried utilities and subsurface anomalies, advancing boreholes, collecting soil and groundwater samples, and installing monitoring, dewatering, injection, and recovery wells. The work enables accurate characterization of subsurface conditions, reduces field risks, and supports construction and remediation requirements.
Geophysical Survey (GPR Survey)
(GPR Survey)ETC provides Ground Penetrating Radar (GPR) surveys as a rapid, non-intrusive
method to support environmental, geotechnical, and civil/industrial works. GPR is
used to identify buried utilities and subsurface anomalies, helping reduce field risks
and optimize drilling, excavation, and investigation locations.
Applications:
-Utility mapping and avoidance planning (pipelines, cables, foundations)
-Identification of subsurface anomalies (voids, buried structures, disturbed – zones)
-Investigation planning and selection of safe drilling / excavation locations
-Support to drilling programs, monitoring well installation, and remediation
infrastructure planning
Deliverables:
-Survey layout plan, interpreted anomaly/utility corridors, and field mark-ups
-CAD/GIS-ready outputs and reporting
Drilling fleet
