Utility Detection & Network Mapping
LOCATE, VERIFY AND SECURE
UNDERGROUND INFRASTRUCTURE.
See what lies beneath.
Make decisions with confidence.
Underground utility detection and georeferencing play a critical role in protecting projects, preventing damage and ensuring regulatory compliance.
Under DT-DICT regulations, maintaining Class A georeferenced utility records has become essential for infrastructure owners, operators and project stakeholders.
Geoliance supports the entire process, from accurately locating underground networks to delivering reliable GIS-ready data that improves asset knowledge and reduces operational risk.
THE GEOLIANCE APPROACH :
ACCURACY THROUGH COMPLEMENTARY TECHNOLOGIES
Geoliance combines multiple non-destructive investigation techniques to provide the most reliable understanding of underground infrastructure :
Every year, our teams complete thousands of kilometres of utility investigations across all major network types, including:
- Gas
- Low- and high-voltage electricity
- Drinking water
- Wastewater and drainage systems
- Telecommunications
- Fibre-optic networks
EVERY INTERVENTION
IS TAILORED TO :
- The operating environment (urban, rural or industrial)
- Project requirements and safety constraints
- The expected level of accuracy
The result: reliable, traceable and regulation-compliant mapping of underground infrastructure.
