Benang provides the infrastructure industry sector with high-quality utility surveys. We achieve this by bringing together the industry’s best people and encouraging and facilitating their continual improvement. This approach means we can plan and perform construction work safely and sustainably, ensuring that the infrastructure is updated and operational for all key stakeholders.
We are specialists in underground utility detection.
Our services extend beyond traditional utility detection and include subsurface services to detect and map geophysical and archaeological assets including voids, geological and archaeological features and more.
Our underground utility locating services include:
- Electromagnetic underground utility detection
- Ground Penetrating Radar (GPR)
- Underground service plans and mapping
- Rod and sonde tracing
- CCTV survey reports
Electromagnetic Underground Utility Detection
By utilising radio detection, electromagnetic line locators and other techniques, we can locate the following underground pipe and cable types:
- Water
- Gas
- Power
- Telecommunications
- Optic fibre
- Storm water
- Sewer
- High voltage power
- Irrigation
Underground Service Plans and Mapping
We can also provide you with a range of underground service plan and underground service map solutions. These solutions can be customised to suit your project scope and budget and include:
- Fully surveyed CAD plans
- Hand drawn ‘mud maps’ (underground service plans)
- Digitally mark-up Google earth images
- Digitally mark-up site photos or plans
Ground Penetrating Radar (GPR)
We can locate underground pipes and cables using advanced Ground Penetrating Radar (GPR) technology. The strengths of GPR include its ability to detect both conductive and non-conductive pipe materials alike (unlike electromagnetic cable locators). GPR can be used to locate:
- Plastic-based pipe materials
- PVC
- Polyethylene
- Underground storage tanks
- Tree roots
- Buried pits and valves
- Ground disturbances
- Voids
Rod and Sonde Tracing
As many underground services do not contain any conductive material, traditional line locating methods are redundant. By using a conductive tracer rod, we can feed it into a range of previously untraceable underground services and locate them. This can be a useful solution for tracing the following:
- Optic fibres
- Sewers
- PVC
- Concrete
- Vitreous clay
- Storm water
CCTV Survey Reports
Our underground utility surveys are not pipe condition surveys, however the use of CCTV in a gravity drainage system or any accessible pipes or ducts, as an addition to the underground utility survey, can provide useful information on the service and structural condition of pipes.
